Boyd’s Bible Dictionary:
(city of victory). Many ancient cities of this name. Probably the one in Epirus is meant (Titus 3:12).
Concise Bible Dictionary:
Place where Paul purposed to winter and where Titus was to meet him (Titus 3:12). The subscription to the epistle refers to the city of Nicopolis of Macedonia; but this has no authority, it was probably the city founded by Augustus on a peninsula in Epirus in Greece. Its ruins are now called Paleoprevesa, 39° N, 20° 44' E.
