(c. 316–270 BC)
Daughter of Ptolemy I and Berenice I. She married King Lysimachus of Thrace, who killed his son by his first marriage possibly by her influence. This resulted in civil strife leading to the king’s death in battle in 281 BC. She then married her half brother Ptolemy, king of Macedonia, who murdered two of her sons and died in battle with the Celts in 279 BC. She returned to Egypt and entered into her third marriage around 276 BC to her full brother, Ptolemy II. She was highly influential at court and was deified with her husband.
