Martyrdom
The sources name the persecution as that of Diocletian and locate the arrest at Canopus, from which the women were brought to Alexandria. The accounts relate that the prisoners were subjected to severe torture before being beheaded; one tradition specifies beatings, whippings, and burning tar among the torments. Cyrus and John, who had gone to strengthen the mother and daughters in prison, shared in their suffering and death.
The martyrs were at first buried in the Church of St. Mark in Alexandria.
