Ptolemy Philopator of Egypt had died in 549. Philip and Antiochus, the kings of Macedonia and Asia, had combined against his successor Ptolemy Epiphanes, a child of five years old, in order completely to gratify the ancient grudge which the monarchies of the mainland entertained towards the maritime state. The Egyptian state was to be broken up; Egypt and Cyprus were to fall to Antiochus Cyrene, Ionia, and the Cyclades to Philip. Thoroughly after the manner of Philip, who ridiculed such considerations, the kings began the war not merely without cause but even without pretext, "just as the large fishes devour the small." The allies, moreover, had made their calculations correctly, especially Philip. Egypt had enough to do in defending herself against the nearer enemy in Syria, and was obliged to leave her possessions in Asia Minor and the Cyclades undefended when Philip threw himself upon these as his share of the spoil. In the year in which Carthage concluded peace with Rome (553), Philip ordered a fleet equipped by the towns subject to him to take on board troops, and to sail along the coast of Thrace. There Lysimachia was taken from the Aetolian garrison, and Perinthus, which stood in the relation of clientship to Byzantium, was likewise occupied. Thus the peace was broken as respected the Byzantines; and as respected the Aetolians, who had just made peace with Philip, the good understanding was at least disturbed. The crossing to Asia was attended with no difficulties, for Prusias king of Bithynia was in alliance with Macedonia. By way of recompense, Philip helped him to subdue the Greek mercantile cities in his territory. Chalcedon submitted. Cius, which resisted, was taken by storm and levelled with the ground, and its inhabitants were reduced to slavery--a meaningless barbarity, which annoyed Prusias himself who wished to get possession of the town uninjured, and which excited profound indignation throughout the Hellenic world. The Aetolians, whose -strategus- had commanded in Cius, and the Rhodians, whose attempts at mediation had been contemptuously and craftily frustrated by the king, were especially offended.
