Ré(rā), island (1991 pop. 13,973), 33 sq mi (85 sq km), Charente-Maritime dept., off La Rochelle, W France, in the Bay of Biscay. The island is largely agricultural; it has oyster beds, some fishing, and a salt-extraction industry. There is also tourism. In the late 1970s a 2.1 mi (3.4 km) bridge was completed connecting the island with the mainland. The citadel, built (1681) by Vauban at Saint-Martin-de-Ré, is now a penitentiary. The name was formerly sometimes spelled Rhé.
(also Ra), in ancient Egyptian mythology and religion the god of the sun, who traveled across the sky in a boat that appeared on the horizon in the morning and sank into the “kingdom of the dead” in the evening. The cult of Re evidently emerged early in the third millennium B.C. By the middle of the third millennium B.C., Re was venerated as the king and father of the gods. Later, Amon was identified with Re (hence the name of the god Amon-Re). The city of Heliopolis was the center of the Re cult.
