Sts. Cosmas and Damian (d. 287 A.D.) were twin brothers born in Arabia. They both became skilled physicians who practiced in Asia Minor. They took no money for their medical services, for which they were well-respected. Because of their charity they drew many to the Catholic faith. During the Christian persecution under the Roman Emperor Diocletian, Cosmas and Damian were targeted, arrested, and tortured. After being miraculously preserved from injury throughout their cruel tortures, holding firm in their faith to the end, they were finally killed by beheading. They were martyred together with their three brothers. Their remains were buried in Syria and many miracles were attributed to them. In gratitude for the healing he received through the intercession of Sts. Cosmas and Damian, Roman Emperor Justinian I (6th c.) restored a church dedicated to their honor in Constantinople, which became a place of pilgrimage. Sts. Cosmas and Damian are regarded as the patron saints of physicians, surgeons, and pharmacists. They are mentioned by name in the Roman Canon of the Mass, and share a feast day on September 26th.
