The monastery of Qennesré or Qenneàrine, founded by St. John Bar Aphtonia around 530 AD on the bank of the Euphrates opposite Europus (Jérabis), provided even more patriarchs of the Church of the East than Qartamin did. It was distinguished because of the body of scholarly Christian works being produced at the time under Sassanian and later Rashidun rule. This manuscript survives in fragmentary form, drawing under the writing of Daniel of Edessa regarding the dealings of the monastery sometime during the post-Arab conquest period.
