Holy Wonderworkers and Unmercenary Martyrs Cyrus and John, and together with them the Martyr Athanasia and her daughters: Theodota, Theoctista and Eudoxia at Canopus in Egypt

Cyrus was a physician in Alexandria who treated the sick without payment. When he was denounced as a Christian under Diocletian, he left for Arabia and became a monk. John, an officer from Edessa, gave up his post and joined him. Hearing that a Christian woman, Athanasia, and her three daughters, Theoctista, aged fifteen, Theodotia, thirteen, and Eudoxia, eleven, had been arrested at Canopus near Alexandria, the two went there to encourage them.

They were seized and tortured in front of the women. Athanasia and her daughters were beheaded, and then Cyrus and John, on 31 January 311. In the 5th century Cyril of Alexandria moved the relics of Cyrus and John to Menouthis near Canopus, where their shrine drew the sick from all over Egypt. The place is still called Abu Qir, from "Abba Cyrus".
