Diocaesareia
Διοκαισάρεια
Diocaesareia (Διοκαισάρεια: Eth. Διοκαισαριεύς).
1.
A place in Cappadocia near Nazianzus. According to Gregorius of Nazianzus, it was a small place. It is mentioned by Ptolemy (5.6); and by Pliny (6.3), who gives no information about it. Ainsworth, on his road from Ak Serai to Kara Hissar, came to a place called Kaisar Koi, and he observes that by its name and position it might be identified with Diocaesarea.
(London Geog. Journal, vol. x. p. 302.) Some geographers take Nazianzus and Diocaesareia to be the same place.
2.
A town of Cilicia Trachea, mentioned by Ptolemy (5.8) and the ecclesiastical authorities. Leake (Asia Minor, p. 117) supposes that it may have been between Claudiopolis (Mout) and Seleuceia (Selefke). [G.L]
