The traditional Greek homelands have been the Greek peninsula and the Aegean Sea, the Southern Italy (Magna Graecia), the Black Sea, the Ionian coasts of Asia Minor and the islands of Cyprus and Sicily. In Plato's Phaidon, Socrates remarks, "we (Greeks) live around a sea like frogs around a pond" when describing to his friends the Greek cities of the Aegean. This image is attested by the map of the Old Greek Diaspora, which corresponded to the Greek world until the creation of the Greek state in 1832. The sea and trade were natural outlets for Greeks since the Greek peninsula is rocky and does not offer good prospects for agriculture.
