 But though Lydiadas was unable to shake Aratus' long-established standing, he maintained his ground, not withstanding the insidious attacks of his rival, and the suspicion that naturally attached to one who had formerly borne the name of tyrant.In 227 BC the conduct of Aratus, in avoiding a battle with Cleomenes III of Sparta at Pallantium, gave Lydiadas fresh cause to renew his attacks, but they were again unsuccessful, and he was unable to prevent the appointment of Aratus for the twelfth time to the office of strategos, in 226 BC.Instead, Lydiadas was elected hipparch and had to serve under the command of his rival.
