Aratus (24.3-24.4)

For Megara seceded from Antigonus and attached herself to Aratus; Troezen and Epidaurus were enrolled in the Achaean League; and Aratus, making a distant expedition for the first time, invaded Attica, and crossing the strait plundered Salamis, his Achaean forces, as though released from prison, obeying his every wish. But the freemen among his prisoners he sent back to the Athenians without ransom, thus laying a foundation for their revolt from Antigonus.

He also made Ptolemy an ally of the Achaeans, with the leadership in war on land and sea. And he was so influential among the Achaeans that, since it was not permissible every year, they chose him general every other year, though, in fact, his wisdom made him their leader all the time. For they saw that he put first and foremost, not wealth, not fame, not friendship with kings, not his own native city’s advantage, but only the growth in power of the Achaean League.
