The Palestinian Authority’s Illegal Army

 https://jewishpress.com/the-palestinian-authoritys-illegal-army/



Given the alarming decline in public – and Congressional – support, Israel in the coming years is likely to face mounting pressure from Washington to recommit to the so-called two-state solution and to reopen negotiations with the Palestinian Authority.

This is true regardless of who wins the 2028 presidential election. It becomes a practical certainty if the winner is a Democrat, or if JD Vance is the Republican nominee and prevails; it is somewhat less likely under a President Rubio.

In any event, Israel should prepare for the worst and assume that sooner or later, the demand will come.

And when it comes, one principle will be paramount. Every serious version of a two-state framework, going back decades, has rested on a single, non-negotiable security requirement – that any future Palestinian state must never be militarized. Such an entity might field national and local police agencies to keep public order; it may not field an army. That was the premise of the Oslo Accords, and it has been the premise of every American peace plan since.

The Palestinian Authority has already broken that principle – and it did so, unfortunately, with Israel’s tacit approval, and at times its active cooperation.

That is the disturbing conclusion of an important new report by Lt.-Col. (res.) Maurice Hirsch for the Jerusalem Center for Security and Foreign Affairs, bluntly titled “The PA’s Massive Army Threatens Millions of Israelis Within Just 22 Kilometers.”

The report’s findings deserve serious attention. Start with the raw figures. The Oslo Accords permitted the PA a civilian police force, capped, in Judea and Samaria, at roughly 12,000 men, equipped with a defined and relatively modest inventory of arms: 4,000 rifles, 4,000 pistols, 120 machine guns, and just 15 armored vehicles. These were the tools of policing – enough weapons to arrest criminals and keep public order, not to wage war.

Today, Hirsch documents, the PA fields approximately 70,000 security personnel, including more than 50,000 in Judea and Samaria – more than four times the 12,000 allowed there under Oslo. The PA’s arsenal is no longer measured in a few thousand light weapons but in tens of thousands of assault rifles and pistols, supplemented by heavy machine guns, RPGs, shoulder-fired missiles, and dozens of armored vehicles.

This is an army – and Israel, shockingly, helped build it. The report traces a series of Israeli-approved weapons transfers in 2007, 2008, 2016, and 2019, as well as a disputed September 2023 shipment reportedly containing 1,500 weapons and eight armored vehicles. Other arms arrived through smuggling and local manufacture that Israel proved unable or unwilling to stop.

Washington underwrote much of the rest, providing $392 million for PA security purposes in 2007 and May 2010 alone for training and equipment, while the European Union poured tens of millions of euros into the PA’s forces over two decades.

In short, while the PA does not control a state, the areas under its control – Area A, which covers about 18% of the West Bank, where the PA has full civil and security control, and Area B, which covers about 22%, where the PA shares security control with Israel – have apparently already been completely or partially militarized.

Why does the “22 kilometers” of the report’s title matter? Because 22 kilometers (about 13½ miles) is roughly the depth that Hamas terrorists penetrated into Israel on October 7, 2023. Hirsch asks a simple and chilling question: What lies within that same distance of the PA’s existing bases in Judea and Samaria? The answer is much of the country.

A 22-kilometer arc from the northern West Bank reaches Afula, Yokne’am, and their surrounding communities – several hundred thousand Israelis. Move west from Tulkarm and Qalqilya, across the Green Line and Israel’s narrow waist, and the number climbs into the millions – the coastal plain, Highway 6, and the approaches to the heart of the country.

By the report’s reckoning, well over two million Israelis live within a single October 7 radius of a military force that isn’t supposed to exist.

And that is only the threat on which the report focuses. Hirsch is careful to note that his scenario deliberately leaves out potential PA military operations directed inward, within Judea and Samaria – attacks that would put hundreds of thousands more in the line of fire, including the Israelis who live in the Jewish communities of the territories, and the many thousands who travel the local roads every day. They wouldn’t be 22 kilometers from the danger. They would be surrounded by it.

While numbers alone do not prove intent, training does. A police force trains to make arrests, direct traffic, and gather evidence. It does not train for armored warfare, artillery, sniping, and parachuting. Yet those are the skills on the PA syllabus. In January 2025, Hirsch notes, 49 PA cadets were participating in such training at a Pakistani military academy. Organizations train men this way to fight conventional wars, not to police civilians.

Hirsch describes the culminating exercise of a PA officers’ course, which featured a drill in stopping a civilian vehicle and pulling out its occupants – a scene the report compares directly to the images of Israelis being dragged from their cars on October 7.

There is no lawful policing purpose for rehearsing the seizure of passengers from a vehicle. That is military or terrorist training, not law enforcement.

Nor is this a case of a few bad actors slipping through the vetting. The PA has made room for terrorists by design. Jibril Rajoub, a senior PA and PLO figure, has boasted that no fewer than 12 percent of the Palestinian terrorists held in Israeli prisons came from the ranks of the PA’s own security forces.

In 2020, the PA’s President Mahmoud Abbas formally approved embedding released terrorists directly into those forces, an arrangement Hirsch says was intended to conceal continuation of payment to terrorists.

An institution that recruits, pays, and promotes such men isn’t helping Israel to prevent the next October 7. It is staffing for it.

Defenders of the arrangement say the PA’s forces coordinate closely with the IDF, share intelligence, and have helped foil Hamas plots in Judea and Samaria. That is true, as far as it goes; but security coordination can be expected to endure only so long as it serves the PA’s interests. Military capabilities, once built, often outlast the political intentions that justified them.

There is a historical parallel that is hard to ignore. In the 1930s, Germany rearmed in open violation of the Treaty of Versailles. Germany’s intended victims, Britain and France, didn’t assist that rearmament. The Soviet Union secretly did, and it paid for the miscalculation in oceans of its own blood.

In the case of the PA, the most probable intended victim has been an active participant. Israel has permitted, and partly financed, the PA’s buildup on the theory that a strong PA is a useful counterweight, a force able to combat and deter Hamas.

That theory could tragically prove to be another conceptzia – another strategic conception that shatters on contact with reality, just as the belief that Hamas was deterred and content to rule Gaza while enriching itself shattered on October 7. The price of being wrong a second time – this time along the country’s most densely populated frontier – could inflict casualties on a scale almost too horrific to contemplate.

Nor would the PA necessarily fight alone. Iran and Hezbollah would almost certainly intervene in such a conflict, assuming they retained the capability to do so.

And Israel should consider another danger as well – the possibility that political upheaval in neighboring Jordan could someday produce a hostile regime. With a population that is majority Palestinian by most estimates, it’s not hard to imagine a radicalized Jordan militarily backing a Palestinian state – or uniting with it ahead of a conflict with Israel. In that event, a heavily armed PA on the West Bank of the Jordan River would constitute a forward military base on Israel’s eastern frontier.

(Recall that from the renamed Roman province Syria Palaestina – formerly known as Judea – through the Byzantine Empire’s Palaestina Secunda and the Umayyad and Abbasid Caliphates’ Jund Filastin district, and according to 19th-century European geography and the initial post-WWI Mandate boundaries, “Palestine” included substantial land east of the Jordan River. The idea that Palestine was ever confined strictly to the land west of the Jordan is a product of the 1921–1922 British administrative decision to exclude the eastern 78 percent of the territory from the provisions of the Balfour Declaration regarding the establishment of a Jewish national home.)

What should Israel do? It should stop playing defense on the diplomatic field and go on the offensive. Instead of waiting to be lectured yet again about a two-state solution, Israel should reframe the entire debate around the core commitment the Palestinians have already broken.

The demand should be simple. The PA must return to what Oslo actually permitted. That means a genuine, verifiable rollback – the force cut to a policing body of the agreed size, the heavy weapons and armored vehicles surrendered, the offensive training programs ended, the foreign military academies closed to PA cadets.

If the Palestinian Authority is truly committed to peace, it has no need for RPGs, armored columns, and cadets schooled in artillery and parachuting.

So, the debate over Palestinian statehood shouldn’t begin with borders or settlements. It should begin with a simple question: Why does an authority that claims to seek peace require an army?

Until that question is answered – and until that army is dismantled – there is nothing meaningful to negotiate.

Migratory Birds Arrive at Hula Lake

https://www.jpost.com/environment-and-climate-change/article-904519

Israel enters ‘fascinating season’ as migratory birds arrive at KKL-JNF’s Hula Lake

The first flamingos of the autumn migration have arrived at KKL-JNF’s Hula Lake, marking the start of a season that will bring millions of birds through Israel’s Upper Galilee in the coming weeks.



The first eight flamingos of the autumn migration season landed at Keren Kayemeth LeIsrael-Jewish National Fund’s (KKL-JNF) Hula Lake last weekend, joining newly arrived shorebirds, songbirds, shanks, ruffs, godwits, grey herons, and spoonbills, KKL-JNF announced.

Larger flocks of migratory bird species are expected to pass through the area in the coming weeks. As the days begin to consistently shorten, migratory birds receive an environmental signal prompting them to begin their journey.

Hula Lake is a major stopover site along the global bird migration route. It provides migratory birds flying between Europe and Africa with a critical place to rest, refuel on the lake’s rich food resources, and remain in a safe environment.

Plain Tiger butterflies, which also migrate seasonally, have joined the many newly arrived bird species.

Hula Lake Park houses an internationally acclaimed bird-watching site

More than 500 million birds representing at least 390 species pass through the Hula Valley in the Upper Galilee every year. Hundreds of thousands of people gather annually to witness the migration.


“It is always exciting to watch the lake fill with life, especially as, during August, the first storks will begin passing through Hula Lake on their migration,” said Inbar Shlomit Rubin, field manager at KKL-JNF’s Hula Lake Park.

“We are now in a fascinating season,” Rubin added. “On the one hand, the last of the nesting birds are still caring for their young. On the other, every morning brings a new surprise as we discover which species arrived at the lake overnight.”

Watch: Oketz dog leads IDF to rocket-filled Hamas tunnel

 


Dramatic bodycam footage shows Oketz Unit military dog searching Hamas terror tunnel in southern Gaza before troops uncovered dozens of rockets and destroyed the underground route.

Troops from the Paratroopers Brigade, under the command of the Gaza Division (143), located an underground route containing dozens of rockets belonging to terrorist organizations operating in the Gaza Strip.

The route was destroyed in cooperation with the engineering forces of the Gaza Division and the Yahalom Unit.

The IDF noted, "The troops are operating in the southern Gaza Strip, to clear the Yellow Line area of terrorist infrastructure above and below ground."

"IDF troops in the Southern Command are deployed in the area in accordance with the ceasefire framework and will continue to operate to remove any immediate threat."

Last week, troops from the 188th Brigade, operating under the Gaza Division, together with Yahalom personnel, dismantled more than 10 underground terror tunnel routes used by the Hamas terrorist organization to advance terrorist activity. One of the tunnel routes had been used to hold hostages.

The troops also located a large quantity of weapons, including rocket launchers, rockets, grenades, explosive devices, and Kalashnikov rifles. In addition, they established new defensive routes and posts in order to strengthen the defensive posture in the area.

Troops from the 188th Brigade, operating under the Gaza Division, have spent the past eight months conducting defensive operations in the southern Gaza Strip to clear the Yellow Line area of terrorist infrastructure.


Irish Government Jet Can't Land in Fog

https://www.dailymail.com/news/article-16029045/Irish-jet-land-fog-navigation-removed-Israel.html

Irish leader's jet 'can't land in fog after he had its navigation system removed... because it was made in Israel'


The Irish leader's jet could allegedly struggle to land in fog after he had its navigation system removed because it was made in Israel.

Taoiseach Micheál Martin's €53million (£45m) Dassault Falcon 6X is supposed to be kitted out with a FalconEye system which helps the plane land in inclement conditions.

But the technology is produced by Israeli company Elbit Systems and given that Ireland's government decided to blacklist defence equipment from the country in 2024, the jet must go without the important feature, the Journal reports.

Former Irish Air Corps pilot Kevin Phipps said that the system provided 'the ability to land in fog when other aircraft would have to divert to another airport'.

It was discovered that the Irish government would need to enter a written agreement with Elbit in order to have the equipment fitted - and this was deemed a step too far for procurement officials in the country.

The ban on technology from the Middle Eastern country did not stop Ireland's four brand new air corps helicopters being fitted with Elbit flight systems, which are essential to get them off the ground.

Alex Gandler, spokesman for the Israeli embassy in the UK, said on X: 'The incompetence and ideological fervour run deep.

An Irish jet can't land in fog because of rabid anti-Israel brain rot.'

The Irish air corps-operated plane can hold 14 passengers and is mainly used to transport the taoiseach and other ministers.

The Falcon 6X was built by French aerospace company Dassault Aviation, which describes the FalconEye system of cameras and sensors as offering 'unprecedented all-weather situational awareness, day or night, in any phase of flight'.

This information is relayed to a computer on the plane and appears on the cockpit display as the pilot attempts to land. 

The Daily Mail has approached the taoiseach's office and the Irish Ministry of Defence for comment.

Israeli company Elbit has been targeted by pro-Palestine protesters across the world including in the UK.

The business is the main manufacturer of the Israeli military's land-based equipment and unmanned aerial vehicles.

Four Palestine Action protesters who smashed their way into an Elbit factory in Bristol carried out 'an act of terrorism', a judge ruled in June as he jailed the quartet.

The wanton violence caused £1.2m worth of damage, left a police officer with a fractured back, and saw the Government subsequently define Palestine Action as a banned organisation.

Ireland has taken a hardline on Israel in recent years and banned Itamar Ben-Gvir, the country's security minister, as well as Bezalel Smotrich, the finance minister, from entering.

Ireland’s new government jet was purchased without FalconEye, an Elbit co-developed system that helps aircraft land in fog


Ireland's new government jet, which cost the republic €53m., was purchased without FalconEye, a technology co-developed by Dassault Falcon and Israeli defense giant Elbit Systems, that is essential for the aircraft to land in foggy weather, local media reported on Tuesday.

FalconEye sits on the plane's nose and helps it to land in foggy weather, or in other weather conditions that limit visibility, Irish outlet The Journal noted.

According to Dassault Falcon's official website, it is "an advanced combined vision system (CVS) developed by Dassault Aviation in partnership with Elbit Systems. Designed for executive and military jets, it merges enhanced real-world video (EVS) with database-driven synthetic terrain mapping (SVS) to provide pilots with unprecedented situational awareness in zero-visibility conditions like fog, snow, or darkness."

The jet, a Dassault Falcon 6X, is primarily used to transport the Irish Taoiseach (prime minister), as well as other government ministers and officials, when traveling on official state business.

The new jet was delivered in December 2025, and can carry 14 passengers. It is operated by the Irish Air Corps (the military's air force).

The FalconEye provides "the ability to land in fog when other aircraft would have to divert to another airport," former IAC pilot Kevin Phipps was cited by The Journal as saying.

Irish PM promises not to purchase equipment featuring Israeli technology

Taoiseach Micheal Martin, in 2024 when serving as foreign minister, said that Ireland would not purchase equipment that features Israeli-made products, Irish media cited.

Despite this, The Journal found that four helicopters belonging to the IAC were delivered with flight systems co-developed by Elbit and Airbus, as "the craft cannot be built without them."

Additionally, a maritime patrol craft was delivered with an Israeli-made radar, The Journal added.

After El-Sayed secures Michigan Dem Senate nod, Jews should vote for those who prioritize their safety, ZOA head says

 


www.jns.org/news/u-s-news/after-el-sayed-secures-michigan-dem-senate-nod-jews-should-vote-for-those-who-prioritize-their-safety-zoa-head-says

After Dr. Abdul El-Sayed’s victory in the Michigan Democratic Senate primary against Rep. Haley Stevens (D-Mich.), Jews should “take very seriously any threats or condemnations of the Jewish people or Israel,” according to Morton Klein, national president of the Zionist Organization of America.

“The safety and security of Jews and the Jewish state should now become the priority when we decide whom to vote for,” he told JNS.

Klein didn’t endorse any candidate but said that “the priority of whom we vote for in this era should be who will protect Jews and the Jewish state best.”

“All other issues become secondary during this era of rising Jew-hatred,” he told JNS.

El-Sayed has described the Israeli government as “bloodthirsty” and “as evil as Hamas,” called Israeli Prime Minister Benjamin Netanyahu a war criminal, opposed the International Holocaust Remembrance Alliance’s working definition of Jew-hatred and defended campaigning with antisemitic commentator Hasan Piker.

Klein urged greater Jewish engagement and advocacy. “Jews now should become more active to protect Jewish and Israeli interests by sending letters regularly to our elected officials, by sending letters to newspapers defending Jews and Israel and condemning our enemies,” he told JNS.

Criticizing Israeli government policies is fair game, as “it’s legitimate to criticize the policies of any government—America, Israel, France or Italy,” Klein said. “But when someone is only condemning the policies of Israel and not saying a word about the policies of Sudan or Somalia or Iran or Iraq or Syria or Turkey, then one has to become suspicious that it’s really Jew-hatred.”

“I criticize Israeli policy all the time,” he told JNS. “I condemn the Oslo Accords and the Gaza withdrawal. I condemn the establishment of a Palestinian state, when some Israelis support it. Obviously, I’m not antisemitic. That is legitimate.”

Klein, whose parents survived the Holocaust, told JNS that growing up, he often heard about “the horror of German and European public officials gaining support and plaudits for their overt Jew-hating statements and policies.”

“Eighty years later we Jews and others see a public overt Jew-hating Israel hater, Abdul El-Sayed, gain public support while legitimizing murderous physical attacks against Jewish children, proclaiming ‘hurt people hurt people,’” he said.

He noted that El-Sayed had “gleefully and proudly” campaigned with “an America-hating, Jew-hating, Israel hater, Hasan Piker, who hideously screamed that ‘America deserved 9-11.’”

“American Jews and others must shed their fears of falsely being called ‘Islamophobic’ and relentlessly and cogently condemn this radical Muslim’s and others’ non-stop bigotry and irrational hatred against Jews,” Klein told JNS. “Every Holocaust survivor and our murdered Holocaust victims demand it.”

How to negotiate with Hamas

https://www.israelnationalnews.com/news/431171

Dr. Kedar to Arutz Sheva: If you're going to make a deal with Hamas, this is how

Dr. Mordechai Kedar says Hamas views agreements as temporary, warns Israel to expect violations and demand strict enforcement.


The possibility of an agreement with Hamas is reigniting the question of whether Israel is repeating past mistakes when it puts trust in a terrorist organization that some say sees deals as merely a tactical means and not a binding obligation.

In an interview with Arutz Sheva-Israel National News, Middle East expert Dr. Mordechai Kedar warns that the safest way to avoid falling into a trap is to refrain from signing deals with Hamas.

"They have a long history of violating agreements," he said. "As far as they're concerned, particularly when it comes to non-Muslims, deception, hiding, stalling for time, and cheating are legitimate means to reach a goal. This modus operandi is based on the Hudaibiya Pact (signed by Mohammed in 628 AD), which they see as merely temporary.

According to Kedar, the Hudaibiya Pact, which various Islamic organizations rely on, is seen as an arrangment which may be violated the moment the balance of power changes. "As long as they don't have power, they sign, but the second they gain power, as far as they're concerned, the agreement is no longer binding. Therefore, anyone who signs with them has to understand that the agreement may be broken the moment they have an interest to do so."

That being said, Dr. Kedar does not rule out signing a deal for diplomatic reasons if it serves a broader Israeli interest. "If we want to make a move that enables diplomatic achievements with the White House or in preparation for another move, we can sign. But we can not make a mistake and think that this is true peace. We have to understand that this is a game."

According to Kedar, one of the mistakes that Israel and the West repeat is the assumption that the other side aspires to the same objectives. "We assume that they want peace, welfare, and a good economy just like we do. But to them, the goal remains the destruction of Israel. As long as they can't do it, they accept temporary agreements."

Kedar believes that, in any case, if a deal is signed, it must be backed by especially tough enforcement mechanisms. "We must state that any violation, even the entry of one rifle into the Gaza Strip, immediately cancels the agreement and allows Israel to return to war. Not to wait until they bring in thousands of weapons and only then to claim that the agreement was violated."

He says that it is not enough to simply prohibit the entry of weapons, but rather the agreement must include clauses that would prevent Hamas from rebuilding its military capabilities. "We have to also ban the weapons training, even with fake wooden weapons. We can not allow them to rebuild their military infrastructure under the guise of other activities. We have to close every possible loophole."

To demonstrate the importance of enforcement, Kedar points to the peace agreement with Egypt. "An agreement at the end of the day is just paper. The question is how it's enforced. If every violation is answered with a fierce and unrelenting response, the other side will understand that there's a real price for violating obligations."

Regarding the possibility that senior Hamas officials could be expelled from the Gaza Strip as part of a future arrangement, Kedar said such a move would be valuable but cautioned against viewing it as a complete solution. “If the commanders leave, that would certainly be a success," he said. “But we must not think the problem ends there. There will always be replacements. At first, they may be less experienced, but within a short time, new leaders will emerge and continue down the same path."

The Antikythera mechanism

https://scienceblog.com/b-the-antikythera-mechanism-recovered-from-a-roman-shipwreck-in-1901-turned-out-to-be-a-hand-cranked-bronze-computer-that-could-predict-eclipses-and-track-the-irregular-orbit-of-the-moon-and-nothing-o/

The Antikythera mechanism recovered from a Roman shipwreck in 1901 turned out to be a hand-cranked bronze computer that could predict eclipses and track the irregular orbit of the Moon, and nothing of comparable mechanical complexity would appear anywhere on Earth for another 1,400 years

A device that predicted celestial events with mechanical precision lay forgotten underwater for two millennia, only to challenge everything we thought we knew about ancient engineering.


For most of human history, the wooden case was rotting on the seabed.

It sat forty-five metres down, off the coast of a small Greek island called Antikythera, in a strait between Crete and the Peloponnese. Around it lay the scattered cargo of the ship that had been carrying it — bronze statues, amphorae, marble pieces from what may have been a Roman raid on Greek treasures. The ship had sunk sometime around 60 BCE. The case, and the object inside it, corroded quietly for two thousand years.

In 1900, a crew of sponge divers taking shelter from a storm surfaced above the wreck by accident. Over the following year, they hauled up whatever they could reach from the seabed, including a lump of bronze and rotted wood roughly the size of a shoebox.

Nobody thought it was important. The statues were the treasure. The lump sat in a storeroom at the National Archaeological Museum in Athens for two years before anyone noticed the gear wheel inside it.

What was inside the lump

The gear wheel was the first sign that something was wrong.

Bronze gears of that precision were not supposed to exist in the ancient world. Roman-era shipwrecks are usually full of standard artefacts of the period — pottery, weapons, coins, occasional jewellery. Nothing about the historical picture of the first century BCE included fine hand-cut gearwork. Yet here was a gear, embedded in a two-thousand-year-old lump, cut with a precision that would not have looked out of place in a nineteenth-century watchmaker’s workshop.

Over the following century, painstaking analysis using X-ray imaging, CT scanning, and eventually three-dimensional computed tomography would reveal what the lump actually contained. At least thirty interlocking bronze gears. A hand crank on the side to drive them. A face on the front showing the positions of the Sun and Moon against the zodiac, with a small rotating sphere — half black, half white — indicating the current phase of the Moon. A back plate with spiral dials tracking longer astronomical cycles including the 19-year Metonic cycle and the 18.2-year Saros cycle used to predict eclipses.

The device was, in the specific engineering sense of the term, a mechanical computer. Turn the crank, and the gears calculated the positions of celestial bodies at any date the user chose. It could predict solar and lunar eclipses decades in advance. It modelled the irregular orbit of the Moon — the fact that the Moon does not travel at a uniform speed around the Earth, but speeds up and slows down as its distance changes — using an epicyclic gearing system in which one gear rotated slightly off-centre from another, mechanically replicating the same variable motion the Moon actually exhibits in the sky.

The Greeks who built it did not know why the Moon’s orbit was irregular. Johannes Kepler would not publish his laws of planetary motion for another sixteen centuries. But they had measured the irregularity precisely enough to model it in bronze.

The 1,400-year gap

Here is where the story becomes genuinely disruptive to the history of technology.

Nothing of comparable mechanical complexity appears in the archaeological record for approximately the next 1,400 years. The Roman Empire produced no comparable object. Medieval Europe produced no comparable object. The Islamic Golden Age, despite substantial advances in astronomical understanding and instrumentation, produced no direct mechanical analogue. It is not until European clockwork begins to appear in cathedral towers around the fourteenth century CE that geared devices of similar precision begin showing up again.

The gap is roughly the same length as the entire distance from the modern era back to the fall of Rome. Fourteen hundred years is not a rounding error. It is a substantial fraction of recorded human history.

The two possibilities are both uncomfortable.

Either the Antikythera mechanism was a genuine one-off — a singular achievement by one Greek engineer or workshop, unmatched by anything before or after, with the knowledge dying when its maker died. Or the mechanism represents a lost technical tradition. A tradition that had been developing for generations before the object we happen to have was built, and that then quietly disappeared in the political and economic disruptions of late antiquity, leaving only this one specimen because it happened to fall into the sea in an accident that preserved it.

Both explanations are strange. The first requires believing that a single ancient engineer somehow leapt over a millennium and a half of technological progress. The second requires believing that a substantial technical tradition disappeared from the historical record so completely that a single specimen is all that survives.

What the object suggests about everything else

The Antikythera mechanism forces a specific question about the history of ancient technology that most historians would prefer not to face.

If a mechanical computer capable of modelling planetary motion existed in the first century BCE and left essentially no trace in the surviving textual, artistic, or archaeological record beyond one waterlogged specimen — what else existed that we don’t know about?

Ancient texts contain scattered references to other geared astronomical devices. Cicero mentions a bronze planetarium supposedly built by Archimedes. Ptolemy describes similar instruments. Roman sources refer to devices that could show the movements of the planets in miniature. These references were, for centuries, dismissed by classicists as literary flourishes or misunderstandings. The specific technology described didn’t fit what the field believed the ancient world was capable of.

The Antikythera mechanism suggests those references were probably accurate. There were other devices. We do not have them. They were probably melted down for the bronze, or lost in wars, or destroyed in the same broader collapse that swallowed the knowledge required to build them.

What survives from the ancient world is not what the ancient world actually made. It is what happened to survive.

The mechanism is now on display at the National Archaeological Museum in Athens, in a case that shows both the corroded original fragments and a modern working reconstruction. Turn the crank on the reconstruction and the small pointer rotates through the zodiac, showing where the Sun and Moon would have appeared to a Greek observer looking up on any specific date in the two thousand years the original was sitting on the seabed.

The mechanism does not know that time has passed. It does not know that its makers have been dead for two millennia. It just keeps calculating, exactly as it was built to do, as if nothing much has changed.
