Thus master of the important city of Kroton, with a citadel near the sea capable of being held by a separate garrison, Dionysius divested the inhabitants of their southern possession of Skylletium, which he made over to aggrandize yet farther the town of Lokri.[46] Whether he pushed his conquests farther along the Tarentine Gulf so as to acquire the like hold on Thurii or Metapontum, we cannot say. But both of them must have been overawed by the rapid extension and near approach of his power; especially Thurii, not yet recovered from her disastrous defeat by the Lucanians. [46] Strabo, vi. p. 261. Profiting by his maritime command of the Gulf, Dionysius was enabled to enlarge his ambitious views even to distant ultramarine enterprises. To escape from his long arm, Syracusan exiles were obliged to flee to a greater distance, and one of their divisions either founded, or was admitted into, the city of Ancona, high up the Adriatic Gulf.[47] On the other side of that Gulf, in vicinity and alliance with the Illyrian tribes, Dionysius on his part sent a fleet, and established more than one settlement. To these schemes he was prompted by a dispossessed prince of the Epirotic Molossians, named Alketas, who, residing at Syracuse as an exile, had gained his confidence. He founded the town of Lissus (now Alessio) on the Illyrian coast, considerably north of Epidamnus; and he assisted the Parians in their plantation of two Grecian settlements, in sites still farther northward up the Adriatic Gulf—the islands of Issa and Pharos. His admiral at Lissus defeated the neighboring Illyrian coast-boats, which harassed these newly-settled Parians; but with the Illyrian tribes near to Lissus, he maintained an intimate alliance, and even furnished a large number of them with Grecian panoplies. It is affirmed to have been the purpose of Dionysius and Alketas to employ these warlike barbarians, first in invading Epirus and restoring Alketas to his Molossian principality; next in pillaging the wealthy temple of Delphi—a scheme far-reaching, yet not impracticable, and capable of being seconded by a Syracusan fleet, if circumstances favored its execution. The invasion of Epirus was accomplished, and the Molossians were defeated in a bloody battle, wherein fifteen thousand of them are said to have been slain. But the ulterior projects against Delphi were arrested by the intervention of Sparta, who sent a force to the spot and prevented all further march southward.[48] Alketas however seems to have remained prince of a portion of Epirus, in the territory nearly opposite to Korkyra; where we have already recognized him, in a former chapter, as having become the dependent of Jason of Pheræ in Thessaly.
