The distance from Constantinople to Melanthias, Villa Caesariana, (Ammian. Marcellin. xxx. 11,) is variously fixed at 102 or 140 stadia, (Suidas, tom. ii. p. 522, 523. Agathias, l. v. p. 158,) or xviii. or xix. miles, (Itineraria, p. 138, 230, 323, 332, and Wesseling's Observations.) The first xii. miles, as far as Rhegium, were paved by Justinian, who built a bridge over a morass or gullet between a lake and the sea, (Procop. de Edif. l. iv. c. 8.)
