The Healer Saints Cosmas and Damian (Greek: Κοσμάς και Δαμιανός, Kosmás kai Damianós; Latin: Cosmas et Damianus; died c. AD 287) were reputed twin brothers, physicians, and early Christian martyrs. They practiced their profession in the seaport of Aegeae, then in the Roman province of Syria.
Accepting no payment for their services led to them being named Anarguroi (Ανάργυροι, “Unmercenaries”); it has been said that, by this, they attracted many to the Christian faith.
