Abba Hor, Besoy (also known as Psoi and Absahi), and Daydara (also known as Didra or Theodora) were Christian martyrs in Egypt in the fourth century. Hor was a soldier. With his brother Besoy, he confessed to his belief in Christianity at Alexandria during the Diocletian Persecution. Hor was subjected to prolonged torture before being pierced by a lance. Besoy was decapitated. Their mother, Daydara, died under torture. They are regarded as saints, with a feast day of 23 June in the Coptic Church and the Assyrian Church of the East. Besoy also has a separate feast day on 24 August.
