The name Italia originally applied only to a part of what is now Southern Italy – according to Antiochus of Syracuse, the southern portion of the Bruttium peninsula (modern Calabria: province of Reggio, and part of the provinces of Catanzaro and Vibo Valentia). But by his time Oenotria and Italy had become synonymous, and the name also applied to most of Lucania as well. The Greeks gradually came to apply the name "Italia" to a larger region, but it was during the reign of Emperor Augustus (end of the 1st century BC) that the term was expanded to cover the entire peninsula until the Alps.^[34]
