[Footnote 137: The description of Dara is amply and correctly
given by Procopius, (Persic. l. i. c. 10, l. ii. c. 13. De
Edific. l. ii. c. 1, 2, 3, l. iii. c. 5.) See the situation in
D'Anville, (l'Euphrate et le Tigre, p. 53, 54, 55,) though he
seems to double the interval between Dara and Nisibis.]
