Ptolemy V Epiphanes
Although still young, Polycrates was second to no one in the king's court, says Polybius, and was accordingly appointed by Ptolemy governor of Cyprus. He discharged the duties of this office with the utmost fidelity and integrity. He thus secured the island for Ptolemy V Epiphanes, the infant son and successor of Ptolemy IV and, on his return to Alexandria in about 196 BC, he brought with him a considerable sum of money for the king's use. He was received at Alexandria with great applause which made him a powerful influence in the kingdom.
