托勒密·克勞諾斯
As Ptolemy Keraunos was becoming more powerful, Arsinoë decided it was time to stop him and conspired against him with her sons. This action caused Ptolemy Keraunus to kill two of her sons, Lysimachus and Philip, while the eldest, Ptolemy, was able to escape and to flee north, to the kingdom of the Dardanians.
