High Quality Content by WIKIPEDIA articles! Saints Cosmas and Damian (Greek: Κοσμάς και Δαμιανός) (also written Kosmas and Damianos) (died ca. 287) were twin brothers, physicians, and early Christian martyrs born in Cilicia, part of today's Turkey. They practiced their profession in the seaport of Ayas, Adana, then in the Roman province of Syria. Accepting no payment for their services led to them being named "Ανάργυροι" (Unmercenary); it has been said that, by this, they attracted many to the Christian faith.
