Saint Anthimus was beheaded in Cilicia (Arabia) with Saints Cosmas and Damian, Leontius and Eutropius. The holy brothers Cosmas and Damian were physicians in Arabia, who believed in Christ. Saints Cosmas and Damian were arrested in Cilicia, and brought before the governor, Lysias. Since they refused to renounce Christianity, the governor ordered the saints to be brutally beaten, and then cast into the sea.
An angel of God rescued them from the sea and brought them to shore. Then the pagans beheaded the saints and three other Christians: Leontius, Anthimus, and Eutropius.
