The island is traversed longitudinally by a chain of wooded mountains, culminating in Mount Delphi (5725 feet). Iron and copper occur in the mountains; and at Carystos, in the south of the island, the marble called cipolino is quarried. Hot springs (sulphur) exist in the north. The east coast is steep and rocky; the west side of the island slopes gradually. The chief towns are Chalcis on the west coast and Carystos (pop. 4119) on the south coast. Pop. of the island, 110,000, mostly Greeks and Albanians. Eubœa was successively subjugated by the Athenians, by Philip of Macedon, by the Romans, by the Venetians (1351), and by the Turks (1470); since 1830 it has been part of the kingdom of Greece.
