Anthony Alcock has kindly translated for us all a Bohairic Coptic account of the life of the Coptic patriarch Isaac (686-689 AD), which he has sent to me for publication. The PDF is here:
- Isaac_life_alcock_2017 (PDF)
Isaac does appear in the History of the Patriarchs of the Coptic Church, but only briefly – this Life is much longer, but also hagiographical. It is translated from the text in the Patrologia Orientalis 11 (1914).
Our thanks to Dr. Alcock for making this accessible!
