Lysimachus of Egypt
Lysimachus (Greek: Λυσίμαχoς; fl. 3rd century BC) was a son of king Ptolemy Philadelphus (283–246 BC) by Arsinoe, the daughter of Lysimachus, king of Thrace. He survived both his brother Ptolemy III Euergetes (246–221 BC), and his nephew, Ptolemy IV Philopator (221–204 BC); but was put to death by Sosibius, the minister and guardian of Ptolemy Epiphanes (204–181 BC).
