Antikythera mechanism: Greek computer that predicted eclipses 2,000 years ago

A shipwreck off the Greek island Antikythera revealed in 1901 a bronze mechanism over 2,000 years old that tracked lunar and solar cycles and eclipses, now seen as the first analogue computer.

In 1901, a group of sponge divers came across, off the Greek island of Antikythera, the remains of a Roman shipwreck. Amid amphorae and statues they found a corroded block of bronze and wood which, for years, no one quite knew how to interpret. In time it would become one of the most closely studied objects in archaeology: a geared mechanism dated to between 150 and 100 BCE, designed to calculate astronomical positions and predict eclipses.

A shipwreck hiding more than it seemed

The artefact is now kept in the National Archaeological Museum of Athens, and its dating places its manufacture in the late 2nd or early 1st century BCE, coinciding with the sinking of the ship that was carrying it.

One of the most widely cited hypotheses, set out in the Antikythera Mechanism Research Project, points to an origin linked to the Corinthian colonies, possibly Syracuse, and therefore to the school of Archimedes, although its exact authorship remains unconfirmed.

The device incorporated more than 30 hand-operated bronze gears that modelled the cycles of the Moon, the Sun and the known planets, and used an epicyclic gearing system, similar to a modern differential, to compensate for orbital irregularities.

On the front, a small sphere, half white and half black, rotated to show the exact lunar phase. On the back, at least four dials represented the Metonic cycle, the Saros cycle, the calendar of panhellenic sporting games and the exeligmos, used to refine eclipse predictions.

Decades of X‑rays to crack a mystery...

Deciphering those pieces, fragmented and corroded by the sea, took decades. In 1959, physicist Derek de Solla Price began studying the 82 recovered fragments; later, together with Greek nuclear physicist Charalampos Karakalos, he captured the first X‑ray and gamma‑ray images of the mechanism’s interior. This revealed 27 gear wheels, some with as many as 127 and 235 teeth, a level of precision that astonished the scientific community and in 2017 led Google to dedicate a doodle to it as the first mechanical computer in history.

...that actually worked?

Not everything is certain. Several subsequent studies by Tony Freeth and Alexander Jones, which simulated the mechanism, found that its indicator for the position of Mars could be off by as much as 38 degrees, a margin of error which the researchers attribute not to manufacturing defects but to the limits of Greek astronomy itself at the time.

A more recent study goes further and suggests that even the smallest manufacturing error could have caused the mechanism to jam or slip, reopening the question of whether the machine ever became fully functional or whether, in practice, it was more cumbersome than useful.

Interest in the mechanism has not faded. Replicas on various scales have been built around the world for educational purposes, such as Mexico’s Monumental Antikythera Mechanism project, designed to train a new generation of physicists and engineers.

Its driving force, researcher Raúl Pérez Enríquez, sums up the enduring fascination with the artefact like this: "It is the universe of the ancient world seen from a new perspective, with the Earth at the centre and the planets revolving around it, just as the Greeks imagined it more than two millennia ago."

Why Is War the Father and King of All?


 July 15, 2026

War, painting by Evi Sarantea.

For a variety of reasons, humans often resort to killing each other. Instead of resolving their differences peacefully, they arm themselves and kill each other until one of them wins the conflict, that is, he has killed most of his opponents. This deadly tradition survives and thrives to this day – in 2026.

Despite international organizations designed to prevent wars like the United Nations, there are alliances like NATO and the European Union, which still prepare and crown war. NATO is basically an American war alliance against Russia. It is an extension of US hegemony in Europe. Meanwhile, deadly conflicts are wrecking Africa, the Middle East and Europe. The war in Ukraine is to some degree WWIII. It has been funded and armed by NATO. This abhorrent race to war justifies the sixth century BCE philosopher Herakleitos who said, “War is the father and king of all” (Hippolytos, Refutation 9.9.4).

True, it is, but why? Wars have been the greatest forces shaping civilization and history. The question is, why are humans incapable of learning to live with each other without mayhem? Such behavior negates civilization. Therefore, what we call civilization to praise ourselves has become civilized barbarism.

Wars in Hellas / Greece

The Greeks discovered democracy, science and beautiful culture. They tried to avoid war through the Olympics and other Panhellenic games and festivals as well as the Oracle at Delphi, which constantly reminded them of their eusebeia / piety for the gods, the speaking of the same Greek language and their Hellenic identity. But these worthwhile institutions and efforts of reconciliation often failed. The result was a series of dehumanizing and de-Hellenizing civil wars like the Peloponnesian War, 431- 404 BCE. This very destructive mayhem started not because of any aggression on the part of the strongest Hellenic city states: Athens, Sparta, Thebes or Corinth. No. The spark for the war came from Sparta because of its fear of rising Athenian influence and power. And once the deadly conflict started, Persia funded Sparta.

After the Greek victories over the Persian invasions of Hellas in 490 and 480-479 BCE, Athens allied with other city states in Ionia / Asia Minor and the Aegean concerned about more Persian invasions. This leadership of Athens gave it international prestige, influence and money with which Athens rebuilt the Parthenon, which the Persians had burned. Sparta did not appreciate a strong rival in Hellas, hence it started the Peloponnesian War that had catastrophic consequences for all Greeks.

The internal strife in Hellas weakened the Greeks and invited conquerors like the Greek Macedonians from Northern Greece and the Romans from the West. The Roman emperor Constantine embraced Christianity in the fourth century. That caused a political and cultural earthquake that demolished nearly all of Hellenic civilization. Christians and other barbarians undid Hellas, overthrowing its temples, architecture, science, schools, libraries and way of life. The Christianization of Hellas was a global catastrophe that sunk Western Europe into darkness: the burning of libraries, crusades and the triumph of barbarism for several centuries.

A very small number of Greek manuscripts survived the march of Christianity into Hellas. These treasures sparked the Renaissance among the Arabs in the 8th century and among the Western Europeans in the 15th century. But the Greeks themselves, made Christians by force, failed to repel the attacks of the Mongol Turks and, in 1453, they lost their freedom. The Western Christian Europeans did not go to the assistance of the Greeks because of theological divisions. Some 400 years later, in the 1820s, the Greeks fought a heroic struggle and won their freedom.

Wars in Europe

Wars continued in Europe. The Greeks spent most of the 19th and early 20th centuries to recapture their land. World War I and especially WWII almost annihilate Greece. In addition, the British and the Germans sowed the seeds of civil war in Greece, 1943-1949. Communist class struggle and American and British capitalist ideologies fought a ferocious conflict in impoverished Greece.

The United States founded the European militarist alliance of NATO, that also included the perennial enemy of Greece, Turkey. This meant that the hot wars of the first half of the 20th century would continue as Cold War conflicts between NATO and the Soviet Union, both armed with the genocidal and extermination nuclear bombs. Islamic Turkey was the only beneficiary of this meaningless regime of tensions and conflicts in Europe. Turkey continued to play one Western Christian country against another and against the communist Soviet Union.

As for Greece, the game was desperate. German occupation, 1941-1944, almost wiped out the country. The civil war, 1943-1949, became another Peloponnesian War: destructive and fratricidal. And just like the Mongol conquest of 1453, when most Greek scholars escaped to Florence, Padua, Venice and Rome, many Greeks left their country in the 1950s and 1960s for other countries in Europe, Australia and America, especially America.

The misfortunes of modern Greece started in 1831. Local enemies of the first president of modern Greece, Ioannes Kapodistrias, did not like him. He came to Greece in 1828 after a brilliant career in Russia, where he was the Secretary of State, 1816-1822. Kapodistrias was also the preeminent diplomat of Europe. In Greece, he tried to create an independent nation state. However, he set the foundations of the modern Greek national state, using his own wealth and Philhellenic contributions for funding the army, schools, courts, hospitals, post office and the expansion of the national borders. He was just to the landless peasants by giving them land. Nevertheless, on September 27, 1831, his local and foreign enemies assassinated him. Britain might have funded the assassins.

After Kapodistrias, the “great” European powers (Britain, France, Russia) sent kings and monarchical institutions to Greece, which undermined the country’s democracy, facilitated the looting of Greek archaeological treasures and weakened ancient traditions. The outcome, as I said, was NATO that included Turkey.

The US, Turkey and NATO

The US was so incense by the influence of the gigantic communist Soviet Union that overlooked the genocidal legacy and policy of Turkey. Like Britain, the US treated Turkey as a fence for the Soviet Union. This blind bias encouraged Turkey’s 1955 pogrom against 85,000 Greek residents of Constantinople / Istanbul. Turkish state-led mobs, armed with torches, knives and iron rods, smashed everything Greek: churches, cemeteries, schools, hospitals, orphanages and thousands of business and commercial stores.

The same disregard for Greece and admiration for Turkey was the reason the US ordered Greece to remove its army from Cyprus. To facilitate such a cowardly act, the Greek army took over the government from 1967 to 1974. The Greek military gave the green light to Turkey, which, in 1974, invaded Cyprus and occupied about 40 percent of the Greek island.

Meanwhile, NATO and the European Union remain silent about Turkish aggression. Even the Greek Prime Minister Kyriakos Mitsotakis downplays the Turkish war threat. If his country dares to expand sovereignty to sea waters that belong to Greece in the Aegean., Turkey threatens war. Mitsotakis mumbled this apocryphal message in early July 2026 NATO conference in Ankara: “My country is in a very delicate neighborhood, facing geopolitical challenges.” NATO and the EU are well aware of this “delicate” situation developing into a volcano in the Aegean but keep silent. The United Nations also treat Turkey like a “normal” state, more than 50 years after Turkey occupied Greek and EU territory.

The Trump administration also has no trouble with genocidal Turkey. In fact, Trump seems to like Erdogan, who continues threatening Greece. Erdogan reads the lips of Trump. In the Ankara NATO meeting, July 7-8, 2026, Erdogan welcomed his distinguished guests with music from an Ottoman-era orchestra.

Evolution of war

Demetrios Karkamanis, a Greek war expert who spent his professional life in the Swedish armed forces, published a couple of articles about the immorality of NATO. None of its nation state members had the courage to raise the human rights violations the government of Erdogan inflicted on Turkish citizens primarily because of the NATO summit in Ankara, much less the systematic violence Turkey has been inflicting on the Greek population and institutions in occupied northern Cyprus for more than 50 years. NATO in early July 2026 was repeating the Trump obsession of spending about $ 50 billion for additional armaments. One wonders all these new guns are going to fight whom? Certainly the Europeans are not deluded or insane to think of fighting Russia directly, though they have been doing that indirectly through the arming and destruction of Ukraine.

The Greek Swedish military expert talked extensively on what Greece needs to do to face the inevitable military confrontation with NATO-embolden Turkey.

I read Karkamanis carefully. He is a strategic thinker. He knows the weapons manufactured and used today. He agreed it was a good idea that Greece purchased 4 very advanced technology warships from France, the so-called Belharra. But he raised critical questions about warfare and strategy. He said that Greece must become self-reliant in weapons and the manufacture of weapons. Her dangerous neighbor, Turkey, has been investing in its military industry and especially in the development of drones, sea and air drones carrying explosives for the annihilation of the enemies they attack. Would the French warships in the Greek navy be able to withstand the ferocity of the drone attacks, the explosive powers of wave after wave of explosives-armed kamikaze drones? And what if the warship destroyed the cheap drones with expensive bullets or missiles? And then he speculated about the algorithmic warfare of tomorrow. Where would such mechanical killing nightmare push humans? Back to the dark ages and mountain caves?

Extinction is the other side of the high tech warfare coin, the potential outcome of still maintaining thousands of “modernized” nuclear weapons by several nation states: US, Russia, China, Pakistan, India, Britain, France, North Korea and Israel: flying them in military aircraft and filling submarines with missiles loaded with the dreadful weapons of extinction; keeping them in air force bases and elsewhere. But instead of discussing disarmament, showing off nukes is becoming fashionable once again.

Nuke fever is unsettling Britain. The Bulletin of the Atomic Scientists, which for decades is acting like the canary in the mine, is warning that Britain is up to something dangerous: “In the last five years,” the Bulletin says, “Britain has quietly moved to increase the maximum size of its nuclear stockpile and revise its nuclear doctrine, and it is now acquiring an additional nuclear capability. In concert with the United States, the UK government is expanding the deployment of non-strategic (tactical) nuclear weapons in a way that could destabilize the strategic balance in Europe.”

Yes, but why is Britain moving around “tactical” nukes? To scare Iran? Ireland? Russia? the EU? We don’t know the depths of insanity behind this extremely dangerous and provocative “doctrine” and policy of Britain. Of course, Britain works closely with its younger brother, the United States, which she educated so well that the US replaced her as world hegemon.

Epilogue

The dogma of Britain to rearm its nuclear forces confirms that war is not about to take a vacation. In such a new jungle of enemies armed to the teeth with a variety of high tech AI weapons, Hellas / Greece must merge her ancient virtues of daring, courage and passion for freedom with the latest high tech technologies of war. No doubt, fighting Turkey in the Aegean will be complex, demanding weapons, daring and strategy. The geography of the Aegean is a tremendous asset to Hellas. Arm each island to defend and fight any invader. The Greeks defeated much larger armies and navies because they had centuries of experience fighting for their freedom. They had studied their potential enemies and knew their strength and weakness. The Turks have a large army but very little experience in fighting naval battles. The Greeks practically lived in the sea for millennia. Belharra, drones, submarines, missiles, air force, electronic warfare and radars become heroic if they are monitored and guided by heroes.

I am not praising warfare. But we live surrounded by danger and enemies. The Greeks are not aggressive. They prefer peace to war. However, their neighbors, the Turks, want what the Greeks have. That’s why the Greeks must develop a strategy to defeat the Turks decisively.

Turkey does not belong to the West and NATO. It’s a jihadist state that has been oppressing non Turks and non-Muslims for centuries. Why is the US and its Western allies refuse to learn this simple truth? Don’t they learn from history? It would be a good idea to talk to the Armenians and Kurds.

From Omnipotence to Democracy



 July 13, 2026

Ceremonies during the annexation of the Republic of Hawaii, 1898. Raising American Flag at United States Annexation Ceremony at ʻIolani Palace, Honolulu, Hawaii. The American marines performing the ceremony are from the USS Philadelphia. Collection: Ray Jerome Baker Collection. Public Domain.

I have been in the United States for most of my life. I witnessed the assassination of President John F. Kennedy. I could never understand why that young, handsome, intelligent and nearly great statesman was cut down. Kennedy was the son of petroleum wealth. However, he and the Soviet leader Nikita Chruschev saved the world from nuclear war annihilation. That experience convinced Kennedy that nuclear weapons and states don’t mix. He intended to abolish nuclear weapons before those genocidal bombs abolished humanity. His murder was fact number one that America was already in deep decline – in 1963. Gangsterism is the antithesis and enemy of democracy and civilization.

In 1963, I was a student at the University of Illinois. With rudimentary knowledge of English, I went through course in zoology. I really did not have a clear idea of what my “major” should be. I loved learning about the Greeks and other people, so I moved to historical studies: ancient, medieval, modern Greek and European diplomatic history, Roman, British, Russian, Soviet and Southeastern European history. Then, as a postdoctoral fellow, I turned to the insights and wisdom of the history of science at Harvard.

The next step in understanding my new home, the United States, was my work on Capitol Hill and the US Environmental Protection Agency. That 27 year experience was fact number two, that the United States was in deep decline. A “democratic republic” allowed a few corporations, domestic and foreign, to legally lace most of the food Americans eat with neurotoxic and carcinogenic chemicals – for the convenience of large farmers. No civilized society would have tolerated such a crime.

The state of America in 2026

America in 2026 is a pilotless supertanker floating in the oceans of planet Earth. In February 2026, Trump and Netanyahu of Israel attacked Iran. This unprovoked war unsettled and angered Pope Leo XIV. He said, a “delusion of omnipotence” is fueling the [US-Israel] war that has left thousands dead.” Indeed, the delusion of omnipotence powers became the hubris that led Trump to start the illegal war against Iran. Trump did not like Leo’s criticism. He accused the Pope of being weak on crime.

President Trump is ruling by edict, thus bypassing and almost shutting down the Constitutional responsibilities of US Congress.

One of the worst decisions of Trump was his undermining of the US Environmental Protection Agency, the country’s sole institutional “protector” of public and environmental health. But Trump undid EPA. An EPA scientist was just fired because he requested the monitoring of microplastics in a fish farm. In my lengthy experience at the US EPA, only the administration of Ronald Reagan in the 1980s nearly matched the corruption and anti-human and anti-environmental health policies of the Trump EPA.

Billionaires funded the election of Trump. And billionaires are behind Trump and his decisions. When they convinced him to eliminate most regulations that assured some health protection to Americans and the natural world, what has been going on in their mind? They are forcing America to the swamp and toxic pollution of the 19th century. They must know, for example, that eating carcinogens and neurotoxins in food mean big trouble for this and future generations. Does this fit their nightmare obsession with AI-human hybrid robots? The billionaire class is hostile to Americans, fact number three that America is in dramatic decline. No democratic society can coexist for long with a minority of plutocrats turning democracy and everything else upside down.

In addition, climate chaos is in the room. Both Trump and his billionaire friends deny the very existence of climate emergency. They pretend they can ignore massive fires, deadly heat waves, the thawing of the permafrost in Alaska, tornadoes, hurricanes, floods, diminishing drinking water and emerging difficulties in raising food. This denial of science and climate change / chaos if fact number four that America is in dangerous decline.

Warring theologies

Nature, however, is almighty. Like the Sun, it makes life possible. The ancient Greeks spoke about the Sun god Helios. They knew something we ignore at our peril. The Sun, the stars, the wind, the rivers and all of the natural world were divine. But the word “divine” in America means something different — in 2026.

In 2026, most people in the Americas, Europe and the Middle East have monotheistic religions (Christianity, Islam and Judaism) that reject the divine nature of the world around us. This is one of the basic reasons why climate chaos and petroleum and other poisons that power agriculture have become existential dangers.

Rod Drehel, conservative Republican, writer and defender of Christianity, had a long discussion with a podcaster of the New York Times. He explained the decline of America in terms of Christianity. He abhorred the wokeness of the “liberals” and the Democratic Party. He also rejected Catholicism because of the massive sexual crimes of Catholic priests against boys. He joined the Orthodox faith and church. He said that Nazism and Soviet communism were products of the murder of god, meaning the Christian god. All these metaphysical illusions, especially his insistence on “transcendence,” drove him to extreme political and theological assumptions on what constitutes decline of a country like the United States.

On July 9, 2026, he tried to make sense of his religious and political realities of America. He said that “we’re living through, at the bottom, a crisis of meaning. People don’t know why they should go on. We have been raised by consumerist culture — both the left and the right have a role to play in this — to believe that more freedom, more wealth is going to make us happy, and it hasn’t. It’s made us more miserable…. I think it all ultimately goes back to a loss of a sense of transcendence. Losing the transcendent sense of life has been deadly for us spiritually, morally and aesthetically.”

I agree with Dreher that consumerism, more “freedom” and more “wealth” failed to improve the lives of most Americans. But he is wrong about wealth. Wealth is still a dream for the overwhelming number of Americans. Moreover, the idea of “transcendence” is strictly an invention of theologians who make a living on organized deception. We should know that neither polytheism nor monotheism are founded on logic, much less facts or science. The gods of polytheists like the ancient Greeks and Romans and the god of monotheists like Christians, Moslems and Jews were human inventions.

Homer and Hesiod explained the “birth” and function of the gods in Greek society. And it made no difference if those deities were real or imagined. The Greeks modeled their behavior to accommodate their culture to the expectations of those divine and mighty beings. After all, the Athenians, probably the best of the Greeks, built their beautiful and exquisite Parthenon to honor Athena, virgin daughter of Zeus and goddess of intelligence, war and freedom.

In America, Christianity was part of the culture of the British and other Europeans who established their hegemony over the country. Christianity justified the genocide of indigenous Americans. And with the coming to power of Trump, “Christian nationalism” spread the alarm of potential crusades and new theocracy. Nationalism baptized by the contaminated waters of religion means trouble. This is threatening the present and future of the country. Conventional Christians face specialized theological groups of Christians who like to believe they are living in the early days of Christian formation and conflict. Some of them pretend to have prophetic powers, others like to assume they are healers. And still others like the charismatic Christians are preparing themselves for crusades. They now proclaim that “God calls Christians into spiritual warfare against demonic forces.”

Molly Worthen, history professor at the University of North Carolina, Chapel Hill, has been studying these unorthodox rebel Christians. “The irony of our secular age,” she says, “is that theology is more powerful than ever.” And that’s where the danger of new crusades becomes factor number five of a declining America.

Congressman Jared Huffman (D-California), is very concerned about the emerging Christian zealots. He is proud he has no religion to confuse him. He says he is a “humanist,” which he defines this way: “To me, it means good without God. It means you don’t need the inducement or fear of an afterlife to have a moral framework and to know your place in the universe. You’re sort of at peace with the reality that, as far as we know, this is it. You get one time around. There are people of faith who sometimes think, well, that must be sad, that must be incomplete. I find it’s just the opposite. It makes this world and our opportunity to be part of it more sacred.”

Epilogue

It’s difficult to make predictions. But as a historian I noticed certain events highlighting changes inimical to democracy. Greek history is full of those seminal events or ideas that sparked warning signals. For example, in the sixth century BCE, a few plutocrats lent money to Athenian farmers. However, several of those farmers could not pay back their debt. The Athenian large farmers / lenders enslaved and sold the indebted farmers. This cruel and unpatriotic decision of Athenians enslaving Athenians rung the bells of civil war. The rulers of Athens invited a former Athenian archon / ruler, Solon, to rewrite the constitution of Athens. Solon did. He abolished slavery and set the foundations of Athenian direct democracy.

Why is this great paradigm of the creation of the first democracy in Western civilization ignored in America? I think Solon becomes paradigmatic in reforming the American constitution: making it a fence around democracy, thus preventing any president from becoming a tyrant or protector of plutocrats. The money in elections in America must stop or the American Republic is doomed, fact number six of the decline of the United States.

In fact, like the Athenian constitution, the revised American constitution should allow citizens to become rich but, when national needs arise, rich people would be responsible to fund defensive weapons or other national priorities.

In addition, the new American constitution would mandate the immediate phasing out of fossil fuels and the transition from fossil fuels to solar and other green energies; the immediate transformation of industrialized farming to small-scale family agriculture producing entirely certified organic food; the phasing out of animal farms; and the separation of church and state.

Of course, these measures require informed and responsible citizens who love their country more than money. But these modest reforms, if done, promise to reduce and eventually eliminate the emerging decline. The US, now 250 years old, has the opportunity to reinvigorate democracy, abandon its destructive war path and save itself and the planet from nuclear war and climate chaos.
