Who they were
Orsisius, a disciple of St Pachomius at Tabennisi, was chosen to succeed him in 348 but resigned in favour of Theodore. After Theodore's death, on St Athanasius's advice, he accepted the office of abbot.
Learned in the Scriptures, he wrote a book of monastic instruction, which St Jerome translated, and left it to his brethren as his testament.
The miracles
The Catholic Encyclopedia does not describe how he came to be honoured as a saint.
Why that counted as sanctity
A humble disciple and successor of St Pachomius.
