Abraham of Ephesus
Abraham of Ephesus was a 6th-century Archbishop of Ephesus in the Byzantine Empire and monastery founder. He is venerated as a saint by both the Catholic and the Orthodox Churches. His feast day is 28 October. Legacy 
During his life as bishop he played an important role in the foundation of a monastery in Constantinople and another in Jerusalem. Two homilies, important for the knowledge and understanding of the ancient Byzantine liturgy, have reached us: One on the feast of the Annunciation and one on the feast of the Presentation of Jesus at the Temple.
