Elias, Probus, and Ares were three Christians, natives of Egypt, who suffered martyrdom during the persecution of the Roman emperor Maximian (305-313). They are commemorated together by the Orthodox Church on December 19. By the synaxarion's account, the three were arrested for ministering to fellow Christians who had been imprisoned for their faith, and after being subjected to torture they were put to death around the year 308.
According to the tradition preserved in the Greek synaxaria, the three had set out from Egypt toward Cilicia in order to minister to the martyrs and confessors held there. While passing through Ashkelon they were seized and brought before the governor Firmilianus, before whom they confessed their faith in Christ. Their commemoration belongs to the wave of suffering that fell upon Christians in Egypt and Palestine during the final great persecution before the peace of the Church.
After their confession and torture, the three did not all meet the same end: Ares completed his martyrdom by being cast into the flames, while Probus and Elias were beheaded by the sword. Because the early sources treat them as a single commemoration, the Church keeps their memory together on one day, and they are venerated jointly as holy martyrs.
