One of the Cyclades, Thíra is also known as Santorini, for St. Irene, the protector of the island. It is a tourism center noted for its wine. Pumice stone and powdered tufa are exported. It was the site of an enormous ancient volcanic explosion rivaling that of TamboraTambora

).

According to tradition, the island was first settled by Phoenicians and later by Laconians under the leader Thera. In the Bronze Age, Thera came under the influence of Crete (see Minoan civilizationMinoan civilization

), but a devastating volcanic eruption (c.1645 B.C.) buried the island's settlements and threw massive amounts of dust into the earth's atmosphere, affecting the weather worldwide. The island was resettled and later occupied (9th cent. B.C.) by the DoriansDorians,
people of ancient Greece. Their name was mythologically derived from Dorus, son of Hellen. Originating in the northwestern mountainous region of Epirus and SW Macedonia, they migrated through central Greece and into the Peloponnesus probably between 1100 and 950 B.C.

Excavations in the E Mediterranean show that ash from the ancient eruption spread over Anatolia and parts of Egypt, and that the tsunami caused by the eruption reached the shores of what is now Israel. It is theorized by some experts that the effects of the eruption were the catalyst for the collapse of Minoan civilization in the subsequent two centuries. Excavations at a Minoan site on Thíra have uncovered many well-preserved frescoes. Some controversial theories have equated ancient Thera with AtlantisAtlantis
, in Greek legend, large island in the western sea (the Atlantic Ocean). Plato, in his dialogues the Timaeus and the Critias, tells of the high civilization that flourished there before the island was destroyed by an earthquake.
