The Armenian Engineers and Scienists of America (AESA) logo is an ancient symbol used in Armenian architecture and carvings. The symbol signifies "Eternal Life" - in Armenan "Haverjoutian Nshan" or "Sign of Eternity". Inscriptions on the walls of some of the ruins of Yerepuni Castle in Armenia bear signs that resemble the turning wheel, which has been adopted by AESA. Some of the ancient ruins of the Urartian Region and ancient Egypt may have displayed this sign as well. Inscriptions resembling a wheel may be found in Echmiadzin also.
The sign of Eternal Life, or turning wheel, was carved on numerous Khach Kars (Cross-Stones) and church walls in ancient Armenia. The following is a list of some of these sites. If you cannot locate the symbol click on photo to see detail.
