The city has been called "Philippopolis" (ΦΙΛΙΠΠΟΠΟΛΙΣ ; , in modern Greek, "Philippoupoli" ) or "the city of Philip", from Greek "Philippos" "horse-lover", most likely in honor of Philip II of Macedon after his death or in honor of Philip V, as this name was first mentioned in the 2nd century BCE by Polybius in connection with the campaign of Philip V. "Philippopolis" was identified later by Plutarch and Pliny as the former "Poneropolis". Strabo identified Philip II's settlement of most "evil, wicked" (ponerotatus) as Calybe (Kabyle), whereas Ptolemy considered the location of Poneropolis different than the rest.
