Saints Cosmas and Damian were twin brothers from Arabia who became renowned physicians in the Roman province of Cilicia during the 3rd century. Deeply committed to their Christian faith, they practiced medicine and surgery entirely without fee, earning them the title Anargyroi ("the silverless" or "unmercenaries"). Their selfless service and miraculous healings—reputedly curing everything from blindness to paralysis—drew many pagans to the Christian faith.
