Euboea or Evia is the second biggest Greek island after Crete island
Its ancient and current name, Εὔβοια, derives from the words εὖ "good", and βοῦς "ox", meaning "the land of the well-fed oxen". In the Middle Ages, the island was often referred to by Byzantine authors by the name of its capital, Chalcis (Χαλκίς) or Euripos (Εὔριπος, the name of the strait that separates the island from the Greek mainland), although the ancient name Euboea remained in use by classicizing authors until the 15th century.
Most important towns: CHALKIS (CHALKIDA), EDYPSOS, ERETRIA, KARYSTOS.
The history of the island of Euboea is largely that of its two principal cities, Chalcis and Eretria, both mentioned in the Catalogue of Ships. Both cities were settled by Ionian Greeks from Attica, and would eventually settle numerous colonies in Magna Graecia and Sicily, such as Cumae and Rhegium, and on the coast of Macedonia.
