1. Brother of Maeandrius, tyrant of Samos. When the Persians invaded the island, towards the commencement of the reign of Dareius Hystaspis, for the purpose of establishing Syloson, the brother of Polycrates, in the tyranny, Maeandrius submitted to them, and agreed to abdicate; but Charillüs, who was somewhat crazy, obtained leave from his brother to fall with a body of soldiers on a party of the most distinguished Persians, who were sitting in front of the acropolis, and waiting for the ratification of the treaty. The consequence of this treacherous murder was a wholesale massacre of the Samians by order of the Persian general, Otanes. (Hdt. 3.144_149.)
