Thermoluminescence dating range
The mechanism’s remains were found as 82 separate fragments of which only seven contain any gears or significant inscriptions.
This machine has the oldest known complex gear mechanism and is sometimes called the first known analog computer, although the quality of its manufacture suggests that it may have had a number of undiscovered predecessors during the Hellenistic Period.
The artifact had been exposed to the weather and had suffered corrosion, although mild given the presence of an electrochemical couple.
This has led some to believe that wine, lemon juice, grape juice, or vinegar was used as an acidic electrolyte solution to generate an electric current from the difference between the electrochemical potentials of the copper and iron electrodes.
It was recovered in 1900–1901 from the Antikythera wreck, but its significance and complexity were not understood until a century later.
The Antikythera mechanism is an ancient analog computer designed to calculate astronomical positions.
In 1974, British science historian and Yale University Professor Derek de Solla Price concluded from gear settings and inscriptions on the mechanism’s faces that the mechanism was made about 87 BC and was lost only a few years later.Some think the Saqqara Bird may be a ceremonial object because the falcon, the bird after which the Saqqara Bird is modeled, is the form most commonly used to represent several of the most important gods of Egyptian mythology, most notably Horus and Ra Horakhty.Some have suggested that the Saqqara Bird may represent evidence that knowledge of the principles of aviation existed many centuries before such are generally believed to have first been discovered.Furthermore, the style of the pottery is Sassanid (224-640).Most of the components of the objects are not particularly amenable to advanced dating methods.
