Who made the byzantine eagle?

The Byzantine eagle was an emblem used by the Byzantine Empire, which existed from the 4th to the 15th century AD. The design of the eagle was based on the Roman imperial eagle, which had been used by the Roman Empire since the 1st century AD. The Byzantine eagle was double-headed, with one head facing the East and the other facing the West. This symbolized the empire's dominion over both the Eastern and Western halves of the Roman Empire. The eagle was often depicted with a nimbus, which is a halo that surrounds the head, symbolizing its sacred nature. The Byzantine eagle was also depicted on coins, mosaics, frescoes, and other works of art.
