The world's first artificial eye

Reconstruction of the Face of a 5000-year old Woman in iran

The face of a 5000 year old Iranian woman has been recently reconstructed with the latest scientific archaeology methods of by Iranian researchers (see Persian-languiage article sourced from Tabnak News-see also English-language posting in Afarensis: Anthropology, Evolution & Science) .

Reconstruction of 5000 year-old woman found at the “Burnt City”. Her face was reconstructed with the latest technology available to anthropologists, paleontologists and forensic experts. She is believed to have been of the ancient city’s upper crust and served as a priestess during her lifetime. The lady is also notable due to the artificial eye that was discovered, still  lodged in the eye socket of her skull after thousands of years.
Maryam Tabeshian of the Cultural Heritage News Agency of Iran (December 10, 2006 had previously noted of researchers having excavated a 4,800-5000 year-old artificial eye along with a skeleton and other findings from the Burnt City (located near the city of Zahedan in Iran’s Seistan-Baluchistan province in the southeast of Iran).

The site of the Burnt City has also yielded numerous interesting finds including an ancient measuring rulerbackgammon game pieces and an animation device.  Researchers have ascertained that the artifical eye belonged to a woman aged 25-30 who hailed from a higher echolon of the local society at the Burnt City.

Interestingly, the woman’s gravesite has also yielded vessels of clay, a leather bag, a mirror of bronze and various other ornaments. Professor Michael Harris, a specialist in the field of optometry at the University of California at Berkeley, has stated that:
It’s unlikely such attention and effort would have been paid to a commoner…She may have been a member of a royal family or an otherwise wealthy individual.”
Prosthetics were of course known in the ancient era with references made to an artificial eye of gold in Hebrew texts (Yer. Ned. 41c; comp. Yer. Sanh. 13c). The prosthetic found in Iran however is different in that it is evidence of the oldest attempt at making this as “realistic” as possible. Professor Mansur Sayyed-Sajadi, who supervised the excavation, has stated:
At first glance, it seems natural tar mixed with animal fat has been used in making [the eye]…whoever made the eye likely used a fine golden wire, thinner than half a millimeter, to draw even the most delicate eye capillaries…”

 
A curious feature of the “eye” are parallel lines that have been drawn around the pupil to form a diamond shape.
Two holes at the sides of the “eye” helped hold it in iplace.  The eye socket of the woman however appears to have developed an abscess as a result fo constant contact with the prosthetic.

 
Further tests are being conducted in iran to determine the exact chemical composition of the prosthetic.
