John bar Penkaye
John or Iohannan bar Penkaye was an East Syriac (Nestorian) writer of the late 7th century. His surname indicates that his parents came from Fenek, on the Tigris (east of Tur Abdin). He was a monk at the monastery of Mar John of Kamul, and later at the monastery of Mar Bassima. Later writers confuse him with John Saba (John of Dalyatha). 
A number of his works have come down to us. Most of them have never been published and are extant only in manuscripts.
