Al Wakidi had likewise written a history of the conquest of Diarbekir, or Mesopotamia (Ockley, at the end of the iid vol.), which our interpreters do not appear to have seen. The Chronicle of Dionysius of Telmar, the Jacobite patriarch, records the taking of Edessa A.D. 637, and of Dara A.D. 641 (Asseman. Bibliot. Orient. tom. ii. p. 103); and the attentive may glean some doubtful information from the Chronography of Theophanes (p. 285 - 287). Most of the towns of Mesopotamia yielded by surrender (Abulpharag. p. 112).
