Book 7
8.3
On being delivered from the Macedonians the Corinthians at once joined the Achaean League; they had joined it on a previous occasion, when the Sicyonians under Aratus drove all the garrison out of Acrocorinth, killing Persaeus, who had been placed in command of the garrison by Antigonus. Hereafter the Achaeans were called allies of the Romans, and in all respects right zealous allies they proved themselves to be. They followed the Romans to Macedonia against Philip; they took part in the campaign against the Aetolians; thirdly they fought side by side with the Romans against the Syrians under Antiochus.
8.4
All that the Achaeans did against the Macedonians or the host of the Syrians they did because of their friendship to the Romans; but against the Aetolians they had a long standing private quarrel to settle. When the tyranny of Nabis in Sparta was put down, a tyranny marked by extreme ferocity, the affairs of Lacedaemon at once caught the attention of the Achaeans.
