Ptolemaeus
18. Son of Sosibius, the minister of Ptolemy Philopator.
He was naturally of a haughty and ambitious character, and these qualities were increased by a visit he paid to the Macedonian court during the minority of Ptolemy Epiphanes. Hence, on his return to Egypt, he made common cause with his brother Sosibius, and took a prominent part against Tlepolemus who held the chief direction of affairs. Their intrigues were however defeated, and the party of Tlepolemus prevailed. (
Plb. 16.22.)
