Νικόπολις, -εως, ἡ Nicopolis, prob. the city of that name in Epirus (CGT, in l): Tit.3:12† (AS)
Thayer:
Nicopolis meaning "city of victory"1) There were many cities by this name, -- in Armenia, Pontus, Cilicia, Epirus, Thrace -- which were generally built or had there name changed, by some conqueror to commemorate a victory. The one in Titus 3:12 seems to refer to the city was built by Augustus in memory of the battle of Actium on a promontory of Epirius. The one in the subscription of Titus seems to refer to Thracian Nicopolis, founded by Trojan on the river Nestus, since he calls it the city of Macedonia.
