006- Byzantine Period
The Church of Saints Cosmas and Damian is among a group of Byzantine churches in the western end of the Roman city of Gerasa (Jerash). It was built in 533 CE in dedication to the martyred twin doctors known for providing free medical care. The church has splendid floor mosaics depicting animals, geometric designs, and donor portraits. There are two neighboring churches: the Church of John the Baptist, whose mosaics are displayed in the Roman Theatre in Amman, and the Church of St. George. A total of 15 churches have been unearthed in Jerash.
