Dadastana
Δαδάστανα
Dadastana (Gen. ae; Δαδάστανα, Ptol. 5.1), an inland town of Bithynia, according to Ptolemy. The Table places it on a road from Nicaea to Juliopolis, and 29 M. P. from Juliopolis. It appears to have been near the borders of Bithynia, as Ammianus says (25.10) the emperor Jovianus on his return from the East came from Ancyra to Dadastana, where he died suddenly.
