Besides being a fortress for military use, the ancient mountain settlement of Rabana-Merquly in modern Iraqi Kurdistan could have also been a 'sanctuary' dedicated to the ancient Persian water goddess Anahita. Architectural structures by a natural waterfall, along with the remains of a possible fire altar, point to the existence of a site of worship, according to Dr. Michael Brown.

The researcher from the Institute of Prehistory, Protohistory, and Ancient Near Eastern Archaeology of Heidelberg University has led excavations there for several years.

The mountain fortress of Rabana-Merquly was an important regional center of the Parthian Empire, which extended over parts of Iran and Mesopotamia approximately 2,000 years ago. Situated on the southwest flanks of Mt. Piramagrun in the Zagros Mountains, it comprises not only the nearly four-kilometer-long fortifications but also two smaller settlements for which it is named.

An international research team studied the archaeological remains on site within the framework of multiple excavation campaigns conducted from 2009 and, most recently, between 2019 and 2022. Overlooking the fortified entrance to Rabana is a rock relief depicting an anonymous ruler, who was most likely a local Parthian vassal king credited with the site's foundation. Inside Rabana Valley, the researchers also discovered a religious complex that could have been dedicated to the goddess Anahita.

The water goddess Anahita was first mentioned in a manuscript collection of the Zoroastrian religion called the Avesta. There, she appears as the celestial source of all the waters on Earth; she is described as a larger-than-life beautiful woman who can assume the form of a flowing stream or waterfall. The cult of Anahita was highly venerated in the western regions of Iraq during Seleucid and Parthian times.

The hypothesis that a possible Anahita shrine is part of the Rabana-Merquly mountain fortress is based mainly on finds of architectural extensions in the natural surroundings of a seasonal waterfall located on the  site. The researchers also discovered an altar-like sculpture nearby carved into an escarpment, where offerings or oil may have been burned.

"The proximity to the waterfall is significant because the association of fire and water elements played an important role in pre-Islamic Persian religion," states Michael Brown.

The site includes the remains of a building where, in 2022, archaeologists unearthed two characteristic burial vessels that were radiocarbon dated to the second to first century BC. That suggests that the shrine was in use during the period in which the fortified settlements of Rabana and Merquly arose. According to Dr. Brown, there may have been a pre-existing shrine that was absorbed into the Anahita cult during the Parthian era, which could have been pivotal in the occupation of the mountain.

At that time many religious sites also functioned as dynastic cult sites honoring the king and his forebears, explains the Heidelberg archaeologist. Worshipers approaching the 'sanctuary' would have passed under the ruler's rock relief and were undoubtedly aware of the strong link between place, royalty, and cult.

"Even if the cult site cannot be definitively attributed to the water goddess Anahita due to the lack of similar archaeological finds for direct comparison, the Rabana sanctuary still provides us with a fascinating glimpse into the regional sacral and geopolitical interconnections during the Parthian era," states Dr. Brown.

The paper is published in the journal Iraq.

Situated within modern-day Iraqi Kurdistan on the southwest flanks of Mt. Piramagrun in the Zagros Mountains, Rabana-merquly was a regional centre within the Parthian Empire, spanning across the regions of Iran and Mesopotamia around 2,000 years ago.

Excavations conducted by the Institute of Prehistory, Protohistory and Ancient Near Eastern Archaeology of Heidelberg University have uncovered architectural features and evidence of a fire altar adjacent to a natural waterfall, suggesting that the site was a sanctuary in dedication to Anahita, an Iranian goddess venerated as the divinity of “the Waters”.

Anahita was first mentioned in the Avesta, a compilation of texts within the Zoroastrian religion. These scriptures depict her as the divine origin of all earthly waters, portrayed as a magnificent and enchanting figure who can transform into a flowing stream or cascading waterfall. During the Seleucid and Parthian eras, the cult of Anahita held great reverence, particularly in the western territories of Iraq.

Dr Michael Brown from Heidelberg University, said: “The proximity to the waterfall is significant, because the association of fire and water elements played an important role in pre-Islamic Persian religion.”

“There may have been a pre-existing shrine that was absorbed into the Anahita cult during the Parthian era, which could have been pivotal in the occupation of the mountain,” added Dr Brown.

This interpretation of the site is mainly based on finds of architectural extensions in the natural surroundings of a seasonal waterfall located on the fortress site. The researchers also discovered an altar-like sculpture nearby carved into an escarpment, where offerings or oil may have been burned.

Persian water goddess “Anahita”




Anahita was pre-Islamic Iran’s most important goddess. Her status was unrivaled by any other Iranian goddess throughout the course of three successive Iranian empires over a period of a thousand years, stemming from her roots as an ancient Indo-European water deity.

She was also the protector of the righteous kings, a tradition that dated back to the Achaemenian empire and lasted until the end of the Sasanian dynasty.

In Persia, Anahita was the deity assigned to water, as well as fertility and prosperity. Anahita is a Protector of Women. The Lady of the Waters and the Lady who rides four horses named wind, rain, clouds, and sleet in her chariot.


Her full name is Aredvi Sura Anahita which means moist, strong, and pure (pure).

Described as a beautiful maiden, strong, tall and pure, she is depicted as wearing a mantle embroidered with gold and holding the baresma (sacred plant) in her hand. Her holy animals are the dove and the peacock. Anahita is sometimes considered as Mithra’s consort.

Anahita is the sole goddess whose name has been immortalized in Persian mythology, alongside Ahura Mazda and Mithra, the two overarching Zoroastrian deities. Inscriptions from the fourth century BCE in Susa and Hamadan provide the first written evidence.

Anahita most likely existed in some form prior to the third millennium BCE, when ancient Persian religion flourished in the Greater Iran region (the Caucasus, Central Asia, South Asia, and West Asia).

Anahita was well-liked and is one of the numerous manifestations of the ‘Great Goddess’ seen in many ancient eastern faiths (such as the Syrian/Phoenician Goddess Anath). She was born in Babylon and spread across Asia Minor, India, and Egypt, where she was portrayed as an armed and riding Goddess. Anahita was linked to Athena, Aphrodite, and possibly Artemis by the Greeks.

In the Middle East, she was associated with Anat. The cult of Anahita spread to Armenia, Persia, and various parts of Western Asia. When Persia conquered Babylon (in the 6th century B.C.E.), Anahita began to show some similarities to the goddess Ishtar. She was identified with the planet Venus, which shows that she probably descended from Ishtar, the main goddess of the region in the pre-Indo-European era.

Many temples were built in Her honor during the reign of King Artaxerxes (436-358 BCE) in Sousa, Ecbatana, and Babylon.

“Great Lady Anahita, glory and life-giver of our nation, mother of sobriety, and benefactor of humanity,” Armenians called out to Anahita.

Modern academics believe Anahita was also revered in Kangavar, Qadamgah, and Bishapur, where sanctuaries that may be recognized as water temples have been discovered.

From Susan Gaviri – Anahita in the Ancient Iranian Mythology:

“…it must not be forgotten that many of the famous fire temples in Iran were, in the beginning, Anahita temples. Examples of these fire temples are seen in some parts of Iran, especially in Yazad, where we find that after the Muslim victory these were converted to Mosques.”

Abstract

The mountain fortress of Rabana-Merquly was a major regional centre of the Parthian period (first century BC) in the Zagros Mountains of Iraqi Kurdistan. The iconography of two rock-reliefs that show an unnamed ruler suggests an association with the vassal kingdom of Adiabene. The exceptional preservation of the fortress's stone walls, undamaged by later agriculture in this highland location, provides an almost complete example of a large, fortified site with two main intramural settlements. Through its ability to control the surrounding landscape, Rabana-Merquly highlights the role of client states on the peripheries of the Parthian and Roman Empires and illuminates the practicalities of territorial control by state authorities in hinterland regions.

Introduction

During the late first millennium BC and early first millennium AD, the foothills and mountains of the north-central Zagros constituted an internal hinterland of the Parthian Empire. This region was marked by distinct cultural and political characteristics—in many respects determined by its geography—and bounded by the Mesopotamian Plain in the west and the Iranian Plateau to the east.

The fortress of Rabana-Merquly is located on the south-western flanks of Mount Piramagrun, near the village of Qarachatan in the Zagros Mountains in Iraqi Kurdistan (Figure 1A). The site overlooks the floodplain of the river Charmaga, a major left-bank tributary of the Lower Zab (ancient Kapros). The construction of the perimeter fortifications took advantage of the rugged highland terrain to encircle two neighbouring settlements, one in the Rabana Valley and the other on the Merquly Plateau (Figure 1B). Despite the impressive scale of construction, Parthian-era occupation of Rabana-Merquly appears to have been relatively short-lived; the main architectural phase is tentatively dated to the first century BC, with parts of the complex showing evidence of reoccupation during Sasanian, Islamic and modern times.

A defining feature of Rabana-Merquly is the two rock-reliefs carved into the cliff-face adjacent to, and plausibly associated with, two gated entrances, depicting an unnamed ruler in ornate attire (see below). While the identity of this individual is a matter of conjecture, Rabana-Merquly would have been close to the south-eastern frontier of the vassal kingdom of Adiabene, within the dominion of the Parthian (or Arsacid) Empire. Although the Parthian conquest of Adiabene is not explicitly recorded in ancient texts, it is known to have been under Arsacid control from the time of Mithridates II (r. 124/123–88/87 BC) (Marciak Reference Marciak2017: 346–47).

Our knowledge of Parthian archaeology and history remains markedly incomplete, despite its evident significance as a major power in the ancient Near East. The following article presents new information about the important regional centre of Rabana-Merquly and examines its role in the landscape of the north-central Zagros and the broader framework of the Parthian Empire. Furthermore, we combine archaeological data with numismatic and textual sources to identify the potential ancient name of this site. By highlighting clear examples of political and military agency, this article aims to challenge the prevailing notion of an inherently weak Parthian state.

The north-central Zagros highlands during the Parthian period

Rabana-Merquly is one of a handful of large, fortified centres in the north-central Zagros (Figure 2) that dominated settlement hierarchies during the Parthian period. The most closely comparable site is Qalʾeh-i Yazdigird, located on the opposite side of the Zagros Mountains in western Iran; it similarly comprises a large enclosure, within which a dispersed array of structures served a variety of defensive, political and sacred purposes (Keall Reference Keall1982). Like Rabana-Merquly, the position of Qalʾeh-i Yazdigird and that of the fortified settlements of Amadiya (Miglus et al. Reference Miglus, Brown and Aguilar2018; Bahrani et al. Reference Bahrani2019) and Qalatga Darband (MacGinnis et al. Reference MacGinnis2020) in Iraqi Kurdistan reflects a desire by their local vassal rulers to control strategic overland communications.


Figure 2. Map of the north-central Zagros region with sites and features mentioned in the text (map by M. Brown; © Rabana-Merquly Archaeological Project).

Several extensive stretches of extramural fortification wall in the region can also potentially be associated with Parthian-era fortified settlements. The longest of these linear barriers is the Gawri Wall, which extends some 115km through Sarpol-e Zahab County in Kermanshah Province, Iran (Alibaigi Reference Alibaigi2019). This massive barrier complements the natural topography, forming a continuous line along the Zagros range; the ceramic finds associated with it suggest that it was, in part or wholly, a Partho-Sasanian construction (Alibaigi Reference Alibaigi2019: 7). The Gawri Wall intersects with the Khorasan section of the Parthian Royal Road crossing the Zagros Mountains; the principal overland route between the eastern and western territories of the Empire is described by Isidorus of Charax in Parthian stations (Walser Reference Walser1985: 145–47). Another large barrier runs along the Darband-i Rania ridge above the site of Qalatga Darband (Brown Reference Brown1958); while the associated blockhouses are probably of Ottoman date, other sections of less well-preserved wall appear to be older. Linear fortifications in the north-central Zagros should be viewed alongside similar Partho-Sasanian monumental constructions elsewhere in the Persian world, the main examples being the Darband and Ghilghildeng walls in the Caucasus, and the Gorgan and Tammisha walls in north-east Iran (Sauer et al. Reference Sauer, Kharanaghi, Khanipour and Naseri2018).

The Parthian-era fortress at Rabana-Merquly was located close to the eastern frontier of the vassal kingdom of Adiabene, beyond which lay the mountainous hinterland of the Zagros. General information about this highland region can be gleaned from Greco-Roman sources that describe tribes such as the Carduchians/Gordyaenes and Cosseans (Balatti Reference Balatti2017: 197–205 & 220–26; Marciak Reference Marciak2017: 241–43). These peoples are typically characterised in the ancient texts as war-like and, perhaps more informatively, by their autonomy from Persian kings. This relationship appears to have taken the form of negotiated allegiance, maintained through reciprocal gift exchange, and involved military support from local rulers in return for taxation rights over those crossing their territory (Balatti Reference Balatti2017: 222 & 287–88). In the case of Adiabene, it is probable that the king engaged in this manner with pastoralist groups along the vassal kingdom's periphery. As a major settlement at the intersection between highland and lowland zones, Rabana-Merquly would probably have played a role in regulating such interactions through military coercion, diplomatic contacts and trade. Roman incursions into Parthian territory during the early first millennium AD are also likely to have encouraged the upkeep of defences close to Adiabene's border.

The mountain fortresses of Rabana and Merquly

The fortifications at Rabana-Merquly can be viewed as an extension of the natural defensive capacity of the surrounding highland landscape. Where gaps in the western escarpment of Mount Piramagrun would otherwise allow access to the valley floor and its upper ridges, walls were constructed to block ingress. The result was a near-continuous barrier, approximately 4000m in length, running from the north-western ridge of Rabana to the south-eastern corner of the Merquly Plateau, with a difference in height between the lowest and highest fortifications of approximately 720m (1180–1900m asl). In combination with cliffs to the north and east, this effectively protected both main intramural settlements.

Qula-Rash Valley and the northern half of the Merquly Plateau, both of which were largely devoid of occupation, separate the two main intramural settlements at Rabana and Merquly (Brown et al. Reference Brown, Rasheed, Dörr and Heiler2020: 96–97). High up on the south side of Qula-Rash is a long wall across the valley that abuts the Merquly escarpment. This architectural feature appears to form part of the wider perimeter fortifications around Rabana-Merquly and implies that the combined whole should be viewed as a single site, with an integrated defence system.

The most substantial built components of Rabana's defences are high up on its north-west flank, comprising a line of perimeter walls that incorporate exterior towers and a bastion (Figure 3). On average, the main stone socle walls, which would have served as the base for mudbrick superstructures, are approximately 1.7m wide and are preserved to an average height of 1.5m. The associated tower walls are some 1.2m wide, with internal chambers measuring approximately 10m2; these dimensions are closely comparable to those of the fortifications at Merquly. The long walls are constructed of irregular stones, with larger boulders at the bases and limestone rubble infill. While no upper walls have survived, several mudbrick fragments were recovered during the excavation of buildings elsewhere at Rabana-Merquly (see below). Given the defensive function of the perimeter walls, and the substantial width of their stone foundations, we surmise that these fortifications were originally at least 5m high.

Figure 3. Rabana upper fortifications (© Rabana-Merquly Archaeological Project).

Along the western flank of Merquly, long walls with exterior towers blocked access from the adjacent slope, and together with fortifications along the southern perimeter, defended the intramural settlement. The highest point of Merquly (called Hangazhall by villagers from nearby Zewe) is on its north-eastern side, directly above the head of the Qula-Rash Valley. Close to this point is a right-angled wall with the hollow foundations of a tower on its south-western corner (Brown et al. Reference Brown, Rasheed, Dörr and Heiler2020: 97–98). In conjunction with the adjoining outcrop, this forms a large, fortified emplacement. At approximately 1900m asl, the Hangazhall fortification provides commanding views south towards the strategically important Tasluja Pass and, in combination with the high towers at Rabana, would have enabled comprehensive surveillance of the adjacent Charmaga Valley, including several nearby sites with Parthian-era occupation (Figure 4). This visual command would have provided warning of any impending attack, potentially allowing nearby communities to take shelter within the fortified settlement of Rabana.


Figure 4. Cumulative viewshed (20km radius) from the three highest towers at Rabana-Merquly (map by M. Brown; © Rabana-Merquly Archaeological Project).

At the south-western corner of the Merquly Plateau, the western and southern segments of perimeter wall abut a large, outcropping rock. Here, on its south side, is one of two matching rock-reliefs, located immediately behind the perimeter wall, near a probable entrance (marked D on Figure 1B). A second relief (marked A on Figure 1B) is positioned in front of a section of perimeter wall, blocking the natural entrance at a corresponding access point to the Rabana Valley (Brown et al. Reference Brown, Rasheed, Dörr and Heiler2020: 93–96) (Figure 5A–B). Overlooked by defensive walls, this extramural public space at Rabana—reached by wide, curvilinear steps—would have allowed for interaction with potentially hostile visitors under tightly controlled conditions, while at the same time signalling the authority of the ruler depicted on the rock-face above.

Figure 5. A) Entrance to Rabana Valley; B) Rabana rock-relief with perimeter wall; C) terrace building, showing Islamic-period occupation (© Rabana-Merquly Archaeological Project).

The focus of occupation at Rabana was in the north-east, where the wadi running through the centre of the valley enters from a narrow gorge, starting higher up the mountain. After heavy rain and snowmelt, the entry point of the wadi into the valley forms an ephemeral waterfall, the base of which was canalised within a monumental stone structure (Figure 6A). Here, excavations in 2017 revealed a staircase cut into the bedrock, with Parthian-era ceramics and iron arrowheads deposited on its surface (Brown et al. Reference Brown, Miglus, Rasheed and Ahmad2018: 65, 70 & 73) (Figure 6B–C). Close by, a small (fire?) altar within a sub-rectangular niche is carved into a smoothed section of escarpment (Figure 6D). The overall impression is of a sanctuary complex, with the prominence of water suggesting a cultic link to the Iranian goddess Anahita (Saadi-nejad Reference Saadi-nejad2021: 66). A rock-cut tomb at the nearby site of Qizqapan also depicts a fire altar on its ornate façade (von Gall Reference von Gall1988). Although most probably of earlier post-Achaemenid construction (Boyce et al. Reference Boyce, Grenet and Beck1991: 105), the Qizqapan monument plausibly remained in use as a site for ancestral veneration concurrent with Parthian-era occupation at Rabana-Merquly (Brown et al. Reference Brown, Rasheed, Dörr and Heiler2020: 105, footnote 25), together forming a wider sacred landscape in the Charmaga Valley.

Excavations of the central citadel at Merquly were conducted by the Sulaymaniyah Directorate of Antiquities in 2009 (Saber et al. Reference Saber, Rejeb and Altaweel2014). The central citadel overlooks 14 freestanding structures that are partially visible on the surface (Figure 7A). These include seven rectangular buildings of standard design, approximately 8–9m wide and 20–22m in length, each with five rooms of roughly equal size. Based on parallels with Roman/Sasanian forts, these structures presumably served, in part, as barracks (Sauer et al. Reference Sauer, Rekavandi, Nokandeh, Lawrence, Altaweel and Philip2020). Of the three examples that were also excavated in 2009, only one immediately below and to the east of the citadel yielded a significant quantity of pottery (Figure 7B). Particularly diagnostic amongst this material are green glazed ceramics that date to the Parthian period, based on parallels from sites including nearby Qalatga Darband (MacGinnis et al. Reference MacGinnis2020: 164–66) and Seleucia on the Tigris (Debevoise Reference Debevoise1934: 34). A further three buildings may represent variations on the ‘barrack’ design, with an approximately 5.5m-wide annex along their northern side. No tiles have been found anywhere at Rabana-Merquly, indicating that roofs were probably of flat, earthen construction.

The defensive function of the fortress presumably extended to a small garrison at Merquly, which would have been well-placed to counter threats from the west and surrounding highlands. Very limited information is available regarding Parthian military organisation. Parthian demands for compensation to rebuild castella, which was sacked by the Roman emperor Caracalla in AD 216 (Dio Cassius Roman History 79.26.3; Cary Reference Cary1927), indicate that the Empire sometimes shared responsibility with vassal monarchs for the upkeep of frontier defences in northern Mesopotamia. According to Hauser (Reference Hauser, Mode and Tubach2006: 310–11, footnote 72), border fortresses were probably manned by the soldiers of a professional standing army, although it is unknown whether these belonged to the Arsacid King of Kings, vassal kings, satraps (provincial governors), or officials of lesser rank.

The apparent architectural relationship between intramural structures, perimeter walls and the two rock-reliefs at Rabana-Merquly strongly suggests that all, or most, of these features were originally contemporaneous components of a planned, Parthian-era settlement. Minor structural renovations to the Merquly citadel indicate subsequent reuse, although it is uncertain whether this occurred later in the Parthian period or in the subsequent Sasanian period (Saber et al. Reference Saber, Rejeb and Altaweel2014: 236–37). Fortifications at the entrance to Rabana were also augmented as part of a significant Islamic-era (AD 636–sixteenth century) reoccupation of the valley (see Figure 5C).

Rock-reliefs and King ʾtlw/Attalos of Adiabene


Each of the two rock-reliefs at the gated entrances to Rabana-Merquly depicts an approximately life-size ruler in ceremonial headgear comprising an ‘upright’ tiara (or hat) and trailing diadem (Figure 8A–B) (Rasheed Reference Rasheed2001; Amedie & Zamua Reference Amedie and Zamua2011; Brown et al. Reference Brown, Miglus, Rasheed and Ahmad2018Reference Brown, Rasheed, Dörr and Heiler2020: 99–103; Khounani & Mohammadifar Reference Khounani and Mohammadifar2018). While the absence of accompanying inscriptions makes it impossible to identify the individual(s) with certainty, informed speculation is possible based upon comparisons with other contemporaneous examples of Parthian official art.


Figure 8. A) Merquly rock-relief; B) Rabana rock-relief; C) statue from Hatra of King ʾtlw/Attalos of Adiabene (illustrations by M. Brown; © Rabana-Merquly Archaeological Project).

Three other rock-reliefs depicting individual Parthian-era rulers are known from the western foothills of the Zagros Mountains: one at Batas-Herir and two at Amadiya (Boehmer & von Gall Reference Boehmer and von Gall1973; Grabowski Reference Grabowski2011; Miglus et al. Reference Miglus, Brown and Aguilar2018; Bahrani et al. Reference Bahrani2019). These three figures all wear diadems and are generally similar in composition to the two from Rabana-Merquly, differing mainly in their headgear, with the Batas-Herir sculpture showing a ‘satrapal’ style of tiara that is associated with the kings of Adiabene (Marciak & Wójcikowski Reference Marciak and Wójcikowski2016: 82 & 84–85). As at Rabana-Merquly, the Amadiya rock-reliefs flank the main entrance to the settlement. The Amadiya and Batas-Herir figures, however, are larger than the life-sized figures at Rabana-Merquly and are shown holding a spear or staff.

Coins provide images of two Adiabenean kings: Abdissar and Monobazos I (Marciak & Wójcikowski Reference Marciak and Wójcikowski2016: 82–83 & 88–89). The earliest attested king of Adiabene is Abdissar, who reigned during the first half of the second century BC and appears on three types of coins wearing a ‘satrapal’ tiara. Monobazos I reigned during the first half of the first century AD and is shown on a single type of bronze coin wearing a ‘dentate’ tiara. While the combination of diadem and ‘upright’ tiara depicted in the Rabana-Merquly reliefs more closely resembles the headgear shown on Arsacid coins, this does not rule out an Adiabenean attribution. Although usually restricted to the Arsacid King of Kings, the right to wear the ‘upright’ tiara was occasionally granted as a privilege to vassals, including King Izates II (r. 55–30 BC) of Adiabene (Josephus Jewish Antiquities 9.20.67; Feldman Reference Feldman1965; Olbrycht Reference Olbrycht1997: 48–49).

By far the closest parallels for the Rabana-Merquly relief sculptures are found in a statue from the city of Hatra, some 230km further west, that portrays King ʾtlw/Attalos of Adiabene (Figure 8C) (Fukai Reference Fukai1960: 142–43; Teixidor Reference Teixidor1967: 1–3; Safar & Mustafa Reference Safar and Mustafa1974: 208; Al-Shawi Reference Al-Shawi1986: 209–10; Marciak & Wójcikowski Reference Marciak and Wójcikowski2016: 92–94). ʾtlw/Attalos is notable for being the only non-Hatrean king depicted at Hatra, leading to speculation that he played an important role in the city's development (Teixidor Reference Teixidor1967: 9). This may likewise apply to his ancestor, Ntwn ͗šr/Natounissar, who is cited in the accompanying inscription (H 21) and in two other Hatrean texts (H 113–114) (Beyer Reference Beyer1998: 33 & 54). The ʾtlw/Attalos statue and the two rock-relief figures from Rabana-Merquly all depict headgear of approximately the same size, fin-like in shape, and with a rounded peak and tied diadem around their bases.

Like the two Rabana-Merquly figures, the Hatra statue wears a full beard. The right arm of all three figures is raised, with an open palm in a gesture of salutation. Each figure wears a torc around the neck. The Hatra figure wears a sleeveless cloak or mantle, as the two Rabana-Merquly figures also probably do where their bodies are depicted in outline. A unique feature of the Rabana-Merquly figures is a clasp that fastens the top of this garment. All three figures wear a belt with hanging tapered ends. The most significant difference in apparel between the Rabana-Merquly rock-reliefs and ʾtlw/Attalos statue is a sword resting on the left hip of the latter—a feature that is also shown on the two Amadiya figures (Amedie & Zamua Reference Amedie and Zamua2011: 237; Miglus et al. Reference Miglus, Brown and Aguilar2018: 119–22).

King Natounissar and Natounia on the Kapros

Two considerations raise the possibility of the identification of the Rabana-Merquly fortress as a city called ‘Natounissarokerta’, or ‘Natounia’, with the accompanying epithet ‘on the Kapros’ (Amedie & Zamua Reference Amedie and Zamua2011: 236; Brown et al. Reference Brown, Rasheed, Dörr and Heiler2020: 103–106). These are, first, the similarities between the Rabana-Merquly rock-reliefs and the statue of King ʾtlw/Attalos of Adiabene from Hatra, and second, the broader landscape setting of the fortress close to a major tributary of the Lower Zab River. Both versions of this ancient place name are inscribed on seven known examples of bronze coins from an unprovenanced mint (Figure 9) (Marciak Reference Marciak2013Reference Marciak2017: 307–308). Similarities with inscriptions from Hatra, including H 21 on the ʾtlw/Attalos statue, are highlighted by Lipiński (Reference Lipiński1982Reference Lipiński2015: 203–205), who reads Ntwn ͗šr/Natounissar (trans. ‘given by Ishtar’) as a throne name belonging to the founder of an Adiabenean dynasty. To paraphrase, the toponym Natounissarokerta can then be understood as a king's royal name, supplemented with the Parthian term denoting a moat or fortification. Such a description could well apply to the perimeter defences around Rabana-Merquly.

Two of the seven inscribed Natounia coins were recovered from a hoard at Nisibis (modern-day Nusaybin in south-east Turkey), on Adiabene's north-west border, that was deposited no later than 32/31 BC (Seyrig Reference Seyrig1955: 100–104). The dates on these coins suggest they may have been minted during the first half of the first century BC (Butcher Reference Butcher1991). Although the ʾtlw/Attalos statue is undated, it was found in the so-called ‘Square Temple’ of the central temenos at Hatra that, according to its dedicatory inscription (H 272), was inaugurated in AD 137/138 (Bertolino Reference Bertolino1995: 39–44; Beyer Reference Beyer1998: 79). While it is conceivable that the portable sculpture could pre-date this building, the gap of 169 or more years between the coins and the dedicatory inscription implies that King ʾtlw/Attalos was not responsible for issuing Natounia's coinage. This does not preclude a more general association with the ruler depicted in the Rabana-Merquly rock-reliefs and another member of the same Adiabenean dynasty who shared their traditional costume. If the equation between Rabana-Merquly and Natounia is accepted, it follows that the rock-reliefs probably depict the city's eponymous founder Ntwn ͗šr/Natounissar, or an immediate descendant. Diagnostic ceramics from Rabana-Merquly are compatible with first-century BC occupation, when Natounia's short-lived coinage was in circulation.

Further potential support for the identification of Rabana-Merquly with Natounia comes from the description of the latter as a royal city of Adiabene ‘on the Kapros’. Rabana-Merquly is located within the watershed of the Lower Zab, which was known as the Kapros in antiquity (Figure 10) (Kessler Reference Kessler1999). This river is approximately 400km long and the land through which it flows is characterised by a sharp decrease in precipitation from east to west, with annual rainfall ranging from approximately 800–900mm around Mount Piramagrun but falling to less than 200mm at its confluence with the Tigris (Buringh Reference Buringh1960: 43). Climate, as well as topography, had a major influence on patterns of riverine settlement in this region. Mount Piramagrun overlooks the floodplain of the Charmaga, which, together with the connecting Surqawshan River, constitutes the largest left-bank tributary of the Lower Zab.

Attaching the names of rivers to place names during antiquity usually served both as a geographical descriptor and to distinguish between two similarly named settlements. In the case of Natounia, this perhaps implies that another site, such as Arbela (modern-day Erbil), the capital of Adiabene, shared the same designation, at least temporarily. Deliberate association with the Kapros River, which was a prominent topographical marker of Adiabene, could also have been intended to validate a new capital by embedding it within an established geopolitical landscape. Although rare, parallels for a more general nominative relationship between sites and the watershed of a river—as opposed only to the main river channel—can be found in the Hellenistic East, at, for example, Ai Khanoum (Alexandria on the Oxus?) and the Amu Darya River basin in Afghanistan and Central Asia (Bernard & Francfort Reference Bernard and Francfort1978: 3–15).

Aside from Rabana-Merquly, the only other known Parthian-era settlement of comparable scale within the Lower Zab watershed is Qalatga Darband. This site is located on flat terrain in the Rania Plain and may have been founded slightly earlier, during the later second century BC (MacGinnis et al. Reference MacGinnis2020: 165–66). Further west along the Lower Zab, a Parthian-era fortress of approximately 1–3ha in size has been investigated on the south bank at Tell Mahuz (Córdoba Reference Córdoba2005: 223). Another possible identification for Rabana-Merquly includes Bdīgar, a fortress of Adiabene mentioned in the fourth-century AD Syriac text Acts of the Persian Martyrs (Jullien Reference Jullien and Gyselen2004: 146; Marciak Reference Marciak2017: 318–20).

Conclusions

Parthian-era fortified sites such as Rabana-Merquly were a relatively short-lived phenomenon, despite the massive scale of their construction, and they represent an outlier to longer-term settlement trends in the north-central Zagros highlands. The very significant resources required for the planning, construction and operation of these sites are nonetheless indicative of state-level agency. If the buildings on Merquly were indeed barracks, as we believe, they provide a rare insight into Partho-Sasanian military architecture and organisation. More generally, such evidence for institutional control contradicts the persistent and arguably unjustified assumption of an innately weak Parthian Empire, which has characterised much scholarship to date (Hauser Reference Hauser, Mode and Tubach2006: 296). In addition to defence and its role as a refugium for neighbouring settlements on the Charmaga floodplain, the Rabana-Merquly complex fulfilled a variety of other functions as a regional centre with low-density occupation (as reflected in its surviving architecture), including as a seemingly important cultic venue at Rabana.

Iconographic similarities between the unnamed ruler(s) depicted in relief at Rabana-Merquly and the statue of King ʾtlw/Attalos at Hatra encourage us to argue for a reliable association between Rabana-Merquly and the kingdom of Adiabene, and, more speculatively, with the site of Natounia on the Kapros. Adiabene is known from historical sources to have expanded its borders between the first century BC and first century AD, within the framework of at least nominal Parthian overlordship (Marciak Reference Marciak2017: 270–71 & 417). The ability of the Rabana-Merquly fortress to survey its surrounding landscape as far south as the Tasluja Pass further implies an extension of Adiabenean authority beyond its core territory between the Upper and Lower Zab Rivers. This connection also highlights the distinct geopolitical role of vassal kingdoms on the periphery of the Parthian—and Roman—Empires in Mesopotamia (Gregoratti Reference Gregoratti, Mæhle, Ravnå and Seland2020), providing insights into the practicalities of territorial control by state authorities in hinterland regions.

Mining Lithium in Argentina

January 14, 2024JPEG


Some of the largest known deposits of lithium—a soft silvery metal that powers batteries in cell phones, laptops, and electric vehicles—lie in one of the driest places on Earth. Much of the surveyed deposits of this metal are located in the arid salt flats of South America, where Chile, Argentina, and Bolivia meet.

The Altiplano-Puna Plateau is an elevated 500,000-square-kilometer area in the Central Andes, and the second highest plateau on Earth after the Tibetan Plateau. Several climatic and geologic factors converged in these dry plains to create large underground lithium deposits.

The Altiplano-Puna sits on one of Earth’s largest known reservoirs of active magma. Although the area receives very little precipitation (less than 30 centimeters [12 inches] a year), hydrothermal fluids associated with this volcanic activity naturally replenish underground aquifers. Over time, rocks containing trace quantities of lithium have weathered causing the metal to build up in the aquifers. According to the U.S. Geological Survey, about half of the world’s measured lithium resources are in these underground deposits in Bolivia, Argentina, and Chile, an area known as the “lithium triangle.”

The image above, acquired by the OLI (Operational Land Imager) on Landsat 8, shows lithium mines in northwestern Argentina’s Jujuy province, near the country’s border with Chile. The light blue evaporation ponds of the mines stand out. The mines are located just south of a large salt flat, known as the Salar de Olaroz.

To harvest the lithium, wells are tapped into the lithium-rich brine beneath the surface. They shunt the brine toward rectangular evaporation ponds lined with plastic. Once there, the briny mixture stays in the ponds for months at a time, where sunshine and wind separate out lithium, salt, and other substances through evaporation. This lithium-rich solution is then processed into lithium carbonate or lithium hydroxide.

Landsat images show the mine immediately adjacent to Salar de Olaroz has expanded several times since 2016, and it is now one of the largest lithium mines in Argentina. In 2018, evaporation ponds were developed for another mine 2 kilometers to the south. Global production of lithium has increased almost ten-fold over the last two decades, from approximately 15,000 metric tons in 2001 to 146,000 metric tons in 2022.

Unlocking answers to ‘Twinkle, Twinkle, Little Star’ earns RAS Fellows prestigious prize

For more than 200 years the nursery rhyme "Twinkle, Twinkle, Little Star" has posed a question astronomers have struggled to answer.

But thanks to three Fellows of the Royal Astronomical Society, we are now unlocking the secrets of just 'what stars are' and what is hidden inside them.


This groundbreaking work has been recognised with the awarding of the prestigious Crafoord Prize in Astronomy 2024 to Douglas Gough, Professor Emeritus at the University of Cambridge, Jørgen Christensen-Dalsgaard, of Aarhus University in Denmark, and Conny Aerts, of KU Leuven in Belgium.

The trio have been honoured by the Royal Swedish Academy of Sciences - which is also responsible for selecting the annual Nobel Prize winners - for uncovering "secrets inside the Sun and stars" and “bringing us new knowledge about phenomena that cannot be perceived by the human eye”.

Bengt Gustafsson, Professor Emeritus at Sweden’s Uppsala University and a member of the prize committee, said the laureates had given us the ability to answer the 19th century lullaby's question 'How I wonder what you are!' “by establishing an entirely new field of research, which studies the way that stars ‘twinkle’".

Of course, the main cause of the twinkling of stars we see from our perspective on Earth is because of the way their light passes through our atmosphere.

The twinkling referred to in this research is due to seismic waves in the stars, which is a much smaller effect.

The three scientists were recognised for discovering that methods used by seismologists to learn about earthquakes on Earth could also be applied to astronomy.

This so-called asteroseismology allows scientists to study the interior of the Sun and stars by monitoring movements on their surfaces caused by internal oscillations similar to soundwaves.

When Professor Gough started his theoretical work, he focused on the Sun and soon had the assistance of his doctoral student, Professor Christensen-Dalsgaard.

The pair, along with hundreds of other researchers, went on to establish a network called the GONG telescopes in 1995, which led to a series of new discoveries such as how the interior of the Sun rotates differently to its outer layer.

Professor Aerts used the same method to learn more about distant stars.

Thanks to this new technology, researchers are now able to measure the radius of stars and the composition of their interiors and to give them a more precise age.

“Twinkle, twinkle, little star, / how I wonder WHAT you are!” is the text of a well-known nursery rhyme,” said Professor Emeritus Gustafsson.

“Small changes that we perceive in a star’s brightness are also due to the oscillations in its interior.

“By establishing an entirely new field of research, which studies the way that stars ‘twinkle’, the laureates have given us the ability to answer the nursery rhyme’s question.

“We can learn more about the stars’ structure and rotation, as well as about the history of the Milky Way.”

Professor Mike Edmunds, president of the Royal Astronomical Society (RAS), congratulated all three RAS Fellows on their prize.

“The award of the Crafoord Prize this year to pioneers in the field of asteroseismology is very welcome, particularly since the three winners are Fellows of the Society,” he said.

“They have made a major contribution to the study of the Sun and stars. I am particularly delighted that one of them is my long-standing colleague Douglas Gough.

“I had the good fortune to learn all about stellar physics from his excellent graduate lectures when I was a research student.

“Many congratulations to all three.”



PLANNING TO STICK AROUND

Deal agreed for 999-year lease on RAS HQ


Professor Mike Edmunds, president of the Royal Astronomical Society (RAS), signs the Burlington House lease agreement (left) with Baroness Scott of Bybrook OBE, Parliamentary Under Secretary of State at the Department of Levelling Up, Housing and Communities. Pictured right is Burlington House and RAS HQ.

The Royal Astronomical Society (RAS) is delighted to announce that an agreement has been reached with the Government to secure a 999-year leasehold on the Society’s headquarters in London.

It protects the 150-year-old scientific and cultural ecosystem at Burlington House by transferring ownership of the 19th century building to the Learned Societies that call it home, including the RAS, the Geological Society (GSL), the Linnean Society (LSL), the Royal Society of Chemistry (RSC) and the Society of Antiquaries (SAL).

In return for the leasehold at a peppercorn rent, the RAS and its Learned Society neighbours will together make a one-off payment to the Department of Levelling Up, Housing and Communities (DLUHC).

The Societies have also agreed an expanded programme of outreach activity to drive the Levelling Up agenda by reaching groups and communities who may not otherwise have the opportunity to engage with their collections and their work.

RAS president Professor Mike Edmunds said he was “over the Moon and jumping a couple of galaxies” following the agreement.

“I am absolutely delighted that for the foreseeable future we will be able to keep our headquarters in Burlington House, surrounded by our fellow Learned Societies,” he added.

“This agreement protects 150 years of our history by ensuring the preservation of our precious library, archives and instrument collection.

“But equally as exciting are the possibilities it opens up for the future, including the potential for innovative public events involving all the Societies around the Courtyard.

“We can also continue to invest in developing the facilities at our central London base – which is so helpful in bringing together our membership on a regular basis – as well as stepping up our activities across the United Kingdom.”

Trustees of the RAS - after careful consideration of the options - concluded that the new deal was not only good value for money but also provided long-term security that will allow the organisation to fulfil its charitable purposes into the future.

The Royal Astronomical Society’s headquarters at Burlington House in London.

Prior to the agreement, the Learned Societies’ place at Burlington House had been under threat because of unaffordable rising rents, but the new deal provides them with a permanent home and protects a national asset for science and heritage.

The scientific hub, which sits at the heart of London’s Piccadilly and is also the residence of the Royal Academy of Arts, was built by the Government in the 19th century to support the work of the Societies that call it home.

Designed to bring people together to disseminate knowledge and serve the public interest, today the ecosystem at Burlington House is playing an important role as the world looks to solve pressing challenges.

From mitigating climate change and biodiversity loss, to understanding the origins of our universe and developing new methods to use the Earth’s resources sustainably, the building is where historical understanding and scientific discovery converge to help find the answers.

With a secure home and continued support from their members and funders, the Societies can now collectively build on their extensive public engagement work, continue to foster research, promote learning for all and inspire and engage communities across the UK and beyond.

Under the new deal, responsibility for the fabric of the building will also transfer from the Government to the charitable organisations, allowing them to focus on ambitions to make their headquarters more accessible and sustainable.

Baroness Scott of Bybrook OBE, Parliamentary Under Secretary of State at the Department of Levelling Up, Housing and Communities, said: “This is a great deal which gives the Learned Societies a strong foundation for the future, and delivers good value for taxpayers at the same time.

“We have been working hard to ensure that they can continue to deliver their valuable contribution to public life, and I am pleased that they now have a permanent home, making these important collections accessible to more people – especially young people.”

Ruth Allington, president of the GSL, said: “Our London base hosts an extensive programme of scientific conferences, meetings, public events and exhibitions, as well as our library and collections.

“This agreement enables us to continue to provide a base for geoscience to thrive, as well as to look forward to welcoming many more thousands of visitors to Burlington House over the coming decades.”


Burlington House is home to the Royal Astronomical Society, The Geological Society, The Linnean Society, The Royal Society of Chemistry, The Society of Antiquaries and Royal Academy of Arts.

Professor Anjali Goswami, president of the LSL, said: “We are delighted to join with the rest of the Courtyard Societies and secure the future Burlington House as a centre of science and heritage.

“The building is not only home to our unique collection, but a hub for our national and international work to understand, value and protect the natural world.

“For the Linnean Society, this deal begins a new stage in our evolution, allowing us to invest in our building and make it more sustainable and accessible.

“It provides a foundation for our strategy to manage our collections and engage with our members and the public to work on behalf of the natural world.”

RSC CEO Dr Helen Pain said: “We welcome the opportunity to secure our long-term occupancy of New Burlington House.

“The outcome of the discussions with the Government enables the continuation of our work in support of our charitable purpose.

“We have taken care to consider all options and make an informed decision based on the priorities of our Society and we are looking forward to the next chapter and working with our neighbours around the Courtyard.”

Professor Martin Millet, president of the SAL, said: “The Society of Antiquaries is delighted to see the long-running issue of its lease at Burlington House successfully resolved with the Government.

“This will enable the Society to further develop its work in supporting research into the human past and communicating such knowledge to a broad and diverse public. We are very grateful to the wide spectrum of people who have actively supported our campaign to achieve this.”
