The Holy Fathers slain at Sinai and Raitho

January 14: The Holy Fathers slain at Sinai and Raitho.

Martyrs of Sinai contested during the reign of Diocletian, about the year 296. Those of Raithu were slain about the middle of the fifth century.

On both occasions, the perpetrators of these massacres were a barbarian tribe called Blemmyes, from parts of Arabia and Egypt.
