the modern Zea, an island in the Ægean Sea, belonging to the group of the Cyclades, fourteen miles off the coast of Attica. It is celebrated as the birthplace of the lyric poets Simonides and Bacchylides; of the philosophers Prodicus and Ariston; and of the physician Erasistratus. There were anciently four towns of considerable importance in the island: Iulis, on the site of which stands the modern Zea; Coressia, the harbour of Iulis; Carthaca on the S.E., and Policiissa on the S.W. shore. From the excellence of the laws regulating the life and morals of the ancient Ceans, the term "Cean laws" passed into a proverb. The present population of the island is about 4000.
