The Epirotes and King Philip on hearing the ambassadors consented to admit the Messenians to alliance; but though the conduct of the Aetolians caused them momentary indignation, they were not excessively moved by it, because it was no more than what the Aetolians habitually did. Their anger, therefore, was short-lived, and they presently voted against going to war with them. So true is it that an habitual course of wrong-doing finds readier pardon than when it is spasmodic or isolated. The former, at any rate, was the case with the Aetolians: they perpetually plundered Greece, and levied unprovoked war upon many of its people: they did not deign either to make any defence to those who complained, but answered only by additional insults if any one challenged them to arbitration for injuries which they had inflicted, or indeed which they meditated inflicting. And yet the Lacedaemonians, who had but recently been liberated by means of Antigonus and the generous zeal of the Achaeans, and though they were bound not to commit any act of hostility towards the Macedonians and Philip, sent clandestine messages to the Aetolians, and arranged a secret treaty of alliance and friendship with them. The army had already been enrolled from the Achaeans of military age, and had been assigned to the duty of assisting the Lacedaemonians and Messenians, when Scerdilaidas and Demetrius of Pharos sailed with ninety galleys beyond Lissus, contrary to the terms of their treaty with Rome. These men first touched at Pylos, and failing in an attack upon it, they separated: Demetrius making for the Cyclades, from some of which he exacted money and plundered others; while Scerdilaidas, directing his course homewards, put in at Naupactus with forty galleys at the instigation of Amynas, king of the Athamanes, who happened to be his brother-in-law; and after making an agreement with the Aetolians, by the agency of Agelaus, for a division of spoils, he promised to join them in their invasion of Achaia. With this agreement made with Scerdilaidas, and with the co-operation of the city of Cynaetha, Agelaus, Dorimachus, and Scopas, collected a general levy of the Aetolians, and invaded Achaia in conjunction with the Illyrians.
