Aratus (30.4-30.5)

Accordingly, until he was general for the third time, Lydiades continued to be held in favour, and held the office every other year in alternation with Aratus; but after displaying an open enmity to him and frequently denouncing him before the Achaeans, he was cast aside and ignored, since it was apparent that he was contending, with a fictitious character, against a genuine and unadulterated virtue.

And just as the cuckoo, in the fable of Aesop, when he asks the little birds why they fly away from him, is told by them that he will one day be a hawk, so it would seem that since Lydiades had once been a tyrant he was never free from a suspicion, which did injustice to his real nature, that he would change again.
