In the meantime Alexander’s embalmed body had been buried at Alexandria, and the two young kings, his son Alexander Ægos and his half-brother Arridæus, had been brought to Macedon.  His mother Olympias put poor Arridæus to death as soon as she could get him into her power.  She had always hated Antipater, and now took part with Polysperchon against Cassander; but this was the losing side.  Polysperchon was beaten, and driven out of Macedon: and she, with her grandson and his mother, the Persian princess Roxana, shut themselves up in Pydna, where Cassander besieged them till he had starved them out, and Olympias surrendered on condition that her life was spared; but Cassander did not keep his word, and sent soldiers to put her to death.  The young king and his mother were kept at Amphipolis till the boy was sixteen years old; and then, growing afraid that he would try to win his father’s throne, Cassander had them both slain.
