Holy Unmercenaries Kosmas and Damianos of Arabia and their brothers Leontios, Anthimos and Euprepios, martyred in Cilicia.
These Kosmas and Damianos, distinct from the Unmercenaries of Asia and of Rome, were physicians of Arabia who healed freely in the name of Christ. They were seized at Aegae in Cilicia in the persecution of Diocletian and, when torments failed to harm them, were beheaded with their three brothers around 287.
Feast day
On the New Calendar, Kosmas and Damianos of Arabia is commemorated on October 17. Churches on the Old (Julian) Calendar keep the feast on October 30 of the civil calendar.
