Or of Nitria
Abba Or of Nitria, also called Hor or Horus, was a Christian ascetic in Egypt who lived around the 4th century AD in Dalga, Nitria (Lower Egypt), the Thebaid, and in the deserts around Shaina. He is one of the lesser-known Desert Fathers, but is nevertheless regarded as one of the "chief among monks", being "a man who stood out among many of the fathers".
