fl. late 5th and early 6th century
'Os, Abba (perhaps fl. late 5th and early 6th century A.D.), was one of the Nine Saints, taking the place of Abba 'Aléf in the traditional Life of Abba Gärima and coming also from Caesarea. He is commemorated on 4 Tahsas (13 December). The Life of 'Os appears in a translation by Cerulli.
