Plutarch, Agis
Bernadotte Perrin, Ed.

16. For Agesilaüs, who was one of the ephors, being now freed from what had kept him in restraint before, shrank from no injustice that brought him money, nay, contrary to the customary arrangement of the calendar, and when the time for it had not yet come, he inserted a thirteenth month¹ and exacted the taxes for it. Moreover, in fear of the victims of his injustice and hated by all men, he kept an armed bodyguard, and would go down to his magistracy under their protection. [2] And as for the kings, he wished men to think that he utterly despised the one, and held Agis in some slight honour more because of his near relationship than because he was king. He also spread reports that he was going to be ephor again.

For this reason his enemies lost no time in taking the great hazard, and banding together, openly brought home Leonidas from Tegea to exercise the royal power. Even the common people were glad to see this done, for they were incensed at their deception in the promised division of the land. [3] Agesilaüs, accordingly, was taken out of the country and saved by his son Hippomedon, who entreated his fellow-citizens, and was beloved of all because of his valour; and as for the kings, Agis fled for refuge to the temple of Athena of the Brazen House, while Cleombrotus went as a suppliant to the sanctuary of Poseidon;² for Leonidas was thought to be more bitter against him, and in fact he left Agis unmolested and went up against Cleombrotus with soldiers. And when he arrived he denounced Cleombrotus angrily because, though a son-in-law, he had plotted against him, robbed him of the royal power, and helped in driving him from the country.
