Cosmas and Damian were unmercenary physicians and miracle-workers. These two saints were brothers, were born in Rome and as children were baptized and brought up in the Christian spirit. They possessed abundant grace from God to heal men and livestock from every disease and suffering, usually by the laying on of hands. They sought no reward for their efforts. They only required of the infirm to believe in Christ the Lord. Inheriting a large estate, they charitably distributed it to the needy and to those in want. At that time, Emperor Galerius reigned in Rome.
