Zosim. l. ii. [c. 30] p. 105. Sozomen, l. ii. c. 3. Theophanes, p. 18 [p. 14, ed. Ven.; vol. i. p. 34, ed. Bonn]. Nicephorus Callistus, 1. vii. p. 48. Zonaras tom. ii. l. xiii. [c. 3] p. 6. Zosimus places the new city between Ilium and Alexandria, but this apparent difference may be reconciled by the large extent of its circumference. Before the foundation of Constantinople, Thessalonica is mentioned by Cedrenus (p. 283) [vol i. p. 496, ed. Bonn], and Sardica by Zonaras, as the intended capital. They both suppose, with very little probability, that the emperor, if he had not been prevented by a prodigy, would have repeated the mistake of the blind Chalcedonians.
