Because of the large space between the mean Sun gear and the front of the case and the size of and mechanical features on the mean Sun gear it is very likely that the mechanism contained further gearing that either has been lost in or subsequent to the shipwreck or was removed before being loaded onto the ship.

Michael Wright was the first person to design and build a model with not only the known mechanism, but also, with his emulation of a potential planetarium system.

He suggested that along with the lunar anomaly, adjustments would have been made for the deeper, more basic solar anomaly known as the "first anomaly". He included pointers for this "true sun", Mercury, Venus, Mars, Jupiter, and Saturn, in addition to the known "mean sun" current time and lunar pointers.

Evans, Carman, and Thorndike published a solution with significant differences from Wright's. They also suggested that rather than accurate planetary indication rendered impossible by the offset inscriptions there would be simple dials for each individual planet showing information such as key events in the cycle of planet, initial and final appearances in the night sky, and apparent direction changes.

This system would lead to a much simplified gear system, with much reduced forces and complexity, as compared to Wright's model. Their proposal used simple meshed gear trains and accounted for the previously unexplained 63 toothed gear in fragment D. They proposed two face plate layouts, one with evenly spaced dials, and another with a gap in the top of the face to account for criticism regarding their not using the apparent fixtures on the b1 gear.

They proposed that rather than bearings and pillars for gears and axles, they simply held weather and seasonal icons to be displayed through a window. In a paper published in Carman, Thorndike, and Evans also proposed a system of epicyclic gearing with pin and slot followers. Freeth and Jones published their proposal in after extensive research and work. They came up with a compact and feasible solution to the question of planetary indication.

They also propose indicating the solar anomaly that is, the sun's apparent position in the zodiac dial on a separate pointer from the date pointer, which indicates the mean position of the Sun, as well as the date on the month dial. If the two dials are synchronised correctly, their front panel display is essentially the same as Wright's. Unlike Wright's model however, this model has not been built physically, and is only a 3-D computer model.

The system to synthesise the solar anomaly is very similar to that used in Wright's proposal. Three gears, one fixed in the centre of the b1 gear and attached to the Sun spindle, the second fixed on one of the spokes in their proposal the one on the bottom left acting as an idle gear, and the final positioned next to that one, the final gear is fitted with an offset pin and, over said pin, an arm with a slot that in turn, is attached to the sun spindle, inducing anomaly as the mean Sun wheel turns.

The inferior planet mechanism includes the Sun treated as a planet in this context , Mercury, and Venus. Each meshes with a gear grounded to the mechanism frame. Each has a pin mounted, potentially on an extension of one side of the gear that enlarges the gear, but doesn't interfere with the teeth; in some cases the needed distance between the gear's centre and the pin is farther than the radius of the gear itself. A bar with a slot along its length extends from the pin toward the appropriate coaxial tube, at whose other end is the object pointer, out in front of the front dials.

The bars could have been full gears, although there is no need for the waste of metal, since the only working part is the slot. Also, using the bars avoids interference between the three mechanisms, each of which are set on one of the four spokes of b1. Five gears and three slotted bars in all. The superior planet systems—Mars, Jupiter, and Saturn—all follow the same general principle of the lunar anomaly mechanism.

It presents a pin and a centre pivot for the epicyclic gear which has a slot for the pin, and which meshes with a gear fixed to a coaxial tube and thence to the pointer. Each of the three mechanisms can fit within a quadrant of the b1 extension, and they are thus all on a single plane parallel with the front dial plate.

In total, there are eight coaxial spindles of various nested sizes to transfer the rotations in the mechanism to the eight pointers. So in all, there are 30 original gears, seven gears added to complete calendar functionality, 17 gears and three slotted bars to support the six new pointers, for a grand total of 54 gears, three bars, and eight pointers in Freeth and Jones' design.

On the visual representation Freeth supplies in the paper, the pointers on the front zodiac dial have small, round identifying stones. He mentions a quote from an ancient papyrus:. Let the stars be set upon the board in accordance with [their] nature except for the Sun and Moon. This is not due to inaccuracies in gearing ratios in the mechanism, but rather to inadequacies in the Greek theory of planetary movements.

The accuracy could not have been improved until first Ptolemy put forth his Planetary Hypotheses in the second half of the second century AD particularly adding the concept of the equant to his theory and then finally by the introduction of Kepler's Second Law in the early 17th century. In short, the Antikythera Mechanism was a machine designed to predict celestial phenomena according to the sophisticated astronomical theories current in its day, the sole witness to a lost history of brilliant engineering, a conception of pure genius, one of the great wonders of the ancient world—but it didn't really work very well!

In addition to theoretical accuracy, there is the matter of mechanical accuracy. Freeth and Jones note that the inevitable "looseness" in the mechanism due to the hand-built gears, with their triangular teeth and the frictions between gears, and in bearing surfaces, probably would have swamped the finer solar and lunar correction mechanisms built into it:.

Though the engineering was remarkable for its era, recent research indicates that its design conception exceeded the engineering precision of its manufacture by a wide margin—with considerable cumulative inaccuracies in the gear trains, which would have cancelled out many of the subtle anomalies built into its design. While the device itself may have struggled with inaccuracies due to the triangular teeth being hand-made, the calculations used and the technology implemented to create the elliptical paths of the planets and retrograde motion of the Moon and Mars by using a clockwork-type gear train with the addition of a pin-and-slot epicyclic mechanism predated that of the first known clocks found in antiquity in Medieval Europe by more than years.

Of special delight to physicists, the Moon mechanism uses a special train of bronze gears, two of them linked with a slightly offset axis, to indicate the position and phase of the moon.

As is known today from Kepler's Laws of Planetary Motion , the moon travels at different speeds as it orbits the Earth, and this speed differential is modeled by the Antikythera Mechanism, even though the ancient Greeks were not aware of the actual elliptical shape of the orbit.

Cicero 's De re publica , a 1st-century BC philosophical dialogue, mentions two machines that some modern authors consider as some kind of planetarium or orrery , predicting the movements of the Sun , the Moon , and the five planets known at that time. Marcellus had great respect for Archimedes and one of these machines was the only item he kept from the siege the second was placed in the Temple of Virtue. The device was kept as a family heirloom, and Cicero has Philus one of the participants in a conversation that Cicero imagined had taken place in a villa belonging to Scipio Aemilianus in the year BC saying that Gaius Sulpicius Gallus consul with Marcellus's nephew in BC, and credited by Pliny the Elder as the first Roman to have written a book explaining solar and lunar eclipses gave both a "learned explanation" and a working demonstration of the device.

When Gallus moved this globe it showed the relationship of the Moon with the Sun, and there were exactly the same number of turns on the bronze device as the number of days in the real globe of the sky. Thus it showed the same eclipse of the Sun as in the globe [of the sky], as well as showing the Moon entering the area of the Earth's shadow when the Sun is in line It showed both solar and lunar eclipses. Pappus of Alexandria stated that Archimedes had written a now lost manuscript on the construction of these devices entitled On Sphere-Making.

One such device is his odometer , the exact model later used by the Romans to place their mile markers described by Vitruvius , Heron of Alexandria and in the time of Emperor Commodus. When the gears pictured, which had square teeth, were replaced with gears of the type in the Antikythera mechanism, which were angled, the device was perfectly functional. If Cicero's account is correct, then this technology existed as early as the 3rd century BC.

Cicero also said that another such device was built "recently" by his friend Posidonius , " It is unlikely that any one of these machines was the Antikythera mechanism found in the shipwreck since both the devices fabricated by Archimedes and mentioned by Cicero were located in Rome at least 30 years later than the estimated date of the shipwreck, and the third device was almost certainly in the hands of Posidonius by that date.

The scientists who have reconstructed the Antikythera mechanism also agree that it was too sophisticated to have been a unique device. This evidence that the Antikythera mechanism was not unique adds support to the idea that there was an ancient Greek tradition of complex mechanical technology that was later, at least in part, transmitted to the Byzantine and Islamic worlds , where mechanical devices which were complex, albeit simpler than the Antikythera mechanism, were built during the Middle Ages.

This text described over a hundred mechanical devices, some of which may date back to ancient Greek texts preserved in monasteries. A geared calendar similar to the Byzantine device was described by the scientist al-Biruni around , and a surviving 13th-century astrolabe also contains a similar clockwork device. On 17 May , Google marked the th anniversary of the discovery with a Doodle. As of [update] , the Antikythera mechanism was displayed as part of a temporary exhibition about the Antikythera Shipwreck, [80] accompanied by reconstructions made by Ioannis Theofanidis , Derek de Solla Price , Michael Wright, the Thessaloniki University and Dionysios Kriaris.

A fully functioning Lego reconstruction of the Antikythera mechanism was built in by hobbyist Andy Carrol, and featured in a short film produced by Small Mammal in A fictionalised version of the device was a central plot point in the film Stonehenge Apocalypse , where it was used as the artefact that saved the world from impending doom.
