Syracuse, anciently a famous city of Sicily, situated on the south-eastern coast of the island, 80 miles SSW. of Messina, was founded by Corinthian settlers about 733 B.C. The colonists seem to have occupied the little isle of Ortygia, which stretches south-east from the shore. The settlement rapidly rose to prosperity, and towards the end of the 6th century B.C. sent out colonies of its own. Little is known of the early political state of Syracuse; but about 485 the ruling families, probably descendants of the original colonists, were expelled by the lower classes of citizens. Gelon (q.v.), despot of Gela, restored the exiles, and at the same time made himself master of Syracuse. He increased both the population and the power of his new state, and won the highest prestige by a great victory over the Carthaginians at Himera. In his time Achradina, a triangular tableland north of Ortygia and on the adjoining mainland, was built upon. This ultimately became the most extensive and populous quarter: it contained the Agora, a temple of Zeus Olympius, the Prytaneum, with a splendid statue of Sappho and fine monuments to Timoleon and the elder Dionysius (q.v.), &c. At a later date, and possibly thus early, there were two other quarters in the city—Tyché, occupying a plateau to the west of Achradina; and Neapolis (New City), stretching along the southern slopes of the plateau, and overlooking the marshes of the Anapus and the Great Harbour, a spacious and well-sheltered bay to the south-west of Ortygia. This islet, however, contained the citadel, which overlooked the docks in the Lesser Harbour on the north.
Hiero (q.v.), the successor of Gelon, was celebrated throughout the Greek world as a patron of the fine arts and of men of genius, as Æschylus, Pindar, &c. In 467 B.C. the democracy again got the upper hand—Thrasýbulus, Hiero's brother and successor, a 'tyrant' of the baser sort, being expelled; and for sixty years a free and democratic government was enjoyed, under which Syracuse flourished more than it had ever done. During this period occurred the great struggle with Athens (415–414 B.C.), and the celebrated siege by the Athenian armament, a contest in which the Sicilian city came off victorious. Nine years later Dionysius (q.v.) restored the 'tyranny' of Gelon, and during a reign of nearly forty years greatly increased the strength and importance of the city (see SICILY). It was he who constructed the docks in the Greater and Lesser Harbours, and surrounded the city with fortifications. His fierce war with Carthage (397 B.C.) raised the renown of Syracuse still higher. The reigns of the younger Dionysius (q.v.) and of Dion, the friend of Plato, were unsettled; but after the restoration of public liberty by Timoleon (343 B.C.) a brief season of tranquillity ensued. In 317 B.C., twenty years after the death of the noble Timoleon, Agathocles, a rude soldier of fortune, once more restored the despotic form of government, which continued, with scarcely an interruption, through the reign (fifty years) of the enlightened Hiero II., the friend and ally of Rome, down to the conquest of the city by the Romans after a siege of two years, in which Archimedes perished (212 B.C.). This event was occasioned during the Hannibalic war by Hieronymus, a rash and vain young man, abandoning the prudent policy of his grandfather, Hiero (q.v.), breaking the alliance with Rome, and joining his and their foes, the Carthaginians. Under the Romans Syracuse slowly declined, though with its handsome public buildings and its artistic and intellectual culture, it always continued to be the first city of Sicily. It was captured, pillaged, and burned by the Saracens in 878 A.D., and after that sunk into complete decay. For ancient Syracuse, see Freeman's History of Sicily.
The modern city (Siracusa) is confined to the original limits, Ortygia, which, however, is no longer an island, but a peninsula. The streets, which are defended by walls and a citadel, are, with few exceptions, narrow and dirty. Syracuse has a cathedral (the ancient temple of Minerva), a museum of classical antiquities, a public library, with some curious MSS., numerous churches, monasteries, and nunneries, the ancient fountain of Arethusa (its waters mingled with sea-water since the earthquake of 1170), and remains of ancient Greek and Roman temples, aqueducts, the citadel Euryalus, a theatre, an amphitheatre, and quarries, besides ancient Christian catacombs. The people manufacture chemicals and pottery, and trade in fruits, olive-oil, wine (exports), wheat, timber, and petroleum (imports) to the annual value of a quarter of a million sterling. Pop. 19,389.
