The Antikythera mechanism could not only predict the timing of eclipses but also reveal characteristics of those eclipses, such as the amount of obscuration, the angular diameter of the moon (which is the angle covered by the diameter of the full moon) and the position of the moon at the time of the eclipse, the study .
Planetary motion in the Antikythera mechanism was accurate to within one degree in 500 years.
The mechanism includes hands or pointers for Mercury, Venus, Mars, Jupiter, and Saturn, all of which are easily visible in the sky, as well as a rotating ball that showed the phases of the moon..
Known to many as the world's first analogue computer, the Antikythera Mechanism is the most complex piece of engineering to have survived from the ancient world.
The 2,000-year-old device was used to predict the positions of the Sun, Moon and the planets as well as lunar and solar eclipses..
Ancient Greek astronomers relied on observation and mathematical calculation to determine the operation of the universe and Earth's place within it..
The mechanism was operated by turning a small hand crank (now lost) which was linked via a crown gear to the largest gear, the four-spoked gear visible on the front of fragment A, the gear named b1.
This moved the date pointer on the front dial, which would be set to the correct Egyptian calendar day..
Abstract.
The Antikythera Mechanism, an ancient Greek astronomical calculator, has challenged researchers since its discovery in 1901.
Now split into 82 fragments, only a third of the original survives, including 30 corroded bronze gearwheels.Mar 12, 2021.
X-ray CT also revealed inscriptions describing the motions of the Sun, Moon and all five planets known in antiquity and how they were displayed at the front as an ancient Greek Cosmos.Mar 12, 2021.
The Antikythera mechanism was discovered in 1901 in the wreckage of an ancient shipwreck off the coast of the island of Antikythera by sponge divers.
Its significance was not recognized until May 1902.
Between 1905 and 2021, the meaning, function, and purpose of the device have been systematically investigated.Aug 2, 2023.
The astrolabe is a calculation and pedagogical tool of Greek origin (2nd century BC).
It made it possible to solve astronomic problems without any calculations.
It identified, for example, the time that the the sun or the stars would rise or set, and the sun's height at its highest point above the horizon, etc..
The ancient Greek astronomical calculating machine, known as the Antikythera Mechanism, predicted eclipses, based on the 223-lunar month Saros cycle..
Ancient Greek astronomers relied on observation and mathematical calculation to determine the operation of the universe and Earth's place within it..
Introduction.
The Antikythera Mechanism is a cultural treasure that has engrossed scholars across many disciplines.
It was a mechanical computer of bronze gears that used ground-breaking technology to make astronomical predictions, by mechanizing astronomical cycles and theories1,2,3,4,5,6,7,8,9.Mar 12, 2021.

The remains of this ancient “computer,” now on display in the National Archaeological Museum in Athens, were recovered in 1901 from the wreck of a trading ship that sank in the first half of the 1st century bce near the island of Antikythera in the Mediterranean Sea.Sep 4, 2023.
Discovery \& Mystery
The ancient shipwreck, dated to c. 70-60 BCE, was discovered at a depth of 45 meters (148 ft) in 1900 off the shores of Antikythera island by Captain Dimitrios Kontos of Symi island and his crew of sponge divers.Aug 2, 2023.
The Antikythera Mechanism persists through time as a collection of artifacts and a model of intellectual achievement.
Thought to have been constructed by Archimedes at Syracuse or by Posidonius at Rhodes, the mechanism was recovered from a ship wreck near the Greek island of Antikythera in 1900-1..
First discovered by divers in a Roman-era shipwreck in 1901, researchers have puzzled over the extraordinary Antikythera mechanism for decades.
The hand-held device dates back 2,000 years and predicted astronomical events, such as the movement of the planets and lunar and solar eclipses, for its ancient Greek users.Mar 17, 2021.
Predicting the positions of the planets along the ecliptic was very difficult for early astronomers.
This task, it turns out, was one of the primary functions of the Antikythera mechanism.
Another function was to track the positions of the sun and moon, which also have variable motions against the stars.Jan 1, 2022.
A 2,000-year-old device often referred to as the world's oldest "computer" has been recreated by scientists trying to understand how it worked.
"Ours is the first model that conforms to all the physical evidence and matches the descriptions in the scientific inscriptions engraved on the mechanism itself," he added. Antikythera mechanism is believed to be the world's oldest computer.
In their 2006 Nature paper 1, Edmunds and his colleagues described it as "a mechanical realization" of Hipparchus' lunar theory. The team and other scholars assumed that the maker of the Antikythera mechanism must have used similar techniques to model the path of the Sun and probably the planets, too.
The Antikythera mechanism's design uses several of the Babylonian period relations. One of the central researchers in the early years of Antikythera research was German philologist Albert Rehm, the first person to understand the mechanism as a calculating machine.
