(d. probably 466),
Abbot of Athribis in Egypt from c.388. His community of monks and nuns grew very large. His government was severe and he added many austerities to the more humane rule of St Pachomius. In 431 he accompanied St Cyril of Alexandria to the Council of Ephesus, where he played an important part in opposing Nestorius. His writings (in Coptic) deal mainly with monastic concerns and exhortations to practise virtue. Feast day in the Coptic Church, 1 July.
