Cosmas and Damian were two Christian brothers in Arabia, both highly skilled doctors. They evangelized through their work, serving many patients for free (they were even nicknamed the silverless). When persecution came, Cosmas, Damian, and their three brothers all faced martyrdom fearlessly. The two holy doctors are credited with many healing miracles.Feast Day: September 26Patronage: Chemists, Dentists, Grocers, Physicians, Physicists
