The holy, glorious, all-laudable Apostle Artemas of the Seventy is commemorated by the Church on October 30 together with Ss. Tertius, Mark, Cleopas, and Justus, and on January 4 with the Seventy.
St. Artemas was bishop of the Lycian city of Lystra, and he died in peace. St. Paul mentions him in his Epistle to Titus (3:12), "I shall send Artemas unto thee."
