In the first days of this spring, the stream of fire issued from Etna, as on former occasions, and destroyed some land of the Catanians, who live upon Mount Etna, which is the largest mountain in Sicily. Fifty years, it is said, had elapsed since the last eruption, there having been three in all since the Hellenes have inhabited Sicily. Such were the events of this winter; and with it ended the sixth year of this war, of which Thucydides was the historian. BOOK IV CHAPTER XII Seventh Year of the War—Occupation of Pylos—Surrender of the Spartan Army in Sphacteria Next summer, about the time of the corn’s coming into ear, ten Syracusan and as many Locrian vessels sailed to Messina, in Sicily, and occupied the town upon the invitation of the inhabitants; and Messina revolted from the Athenians. The Syracusans contrived this chiefly because they saw that the place afforded an approach to Sicily, and feared that the Athenians might hereafter use it as a base for attacking them with a larger force; the Locrians because they wished to carry on hostilities from both sides of the strait and to reduce their enemies, the people of Rhegium. Meanwhile, the Locrians had invaded the Rhegian territory with all their forces, to prevent their succouring Messina, and also at the instance of some exiles from Rhegium who were with them; the long factions by which that town had been torn rendering it for the moment incapable of resistance, and thus furnishing an additional temptation to the invaders. After devastating the country the Locrian land forces retired, their ships remaining to guard Messina, while others were being manned for the same destination to carry on the war from thence. About the same time in the spring, before the corn was ripe, the Peloponnesians and their allies invaded Attica under Agis, the son of Archidamus, king of the Lacedaemonians, and sat down and laid waste the country. Meanwhile the Athenians sent off the forty ships which they had been preparing to Sicily, with the remaining generals Eurymedon and Sophocles; their colleague Pythodorus having already preceded them thither. These had also instructions as they sailed by to look to the Corcyraeans in the town, who were being plundered by the exiles in the mountain. To support these exiles sixty Peloponnesian vessels had lately sailed, it being thought that the famine raging in the city would make it easy for them to reduce it. Demosthenes also, who had remained without employment since his return from Acarnania, applied and obtained permission to use the fleet, if he wished it, upon the coast of Peloponnese.
