(231) Alexander left two sons, Heracles the son of Barsine the daughter of Pharnabazus, and Alexander the son of Roxane the daughter of Oxyartes the Bactrian; this Alexander was born about the time of his father's death, at the start of Philippus' reign.
Olympias the mother of Alexander killed Aridaeus, but then Cassander the son of Antipater executed her and both the sons of Alexander, the one by himself and the other (the son of Barsine) by prompting Polysperchon.
Cassander cast away Olympias' body without a burial, and proclaimed himself king; and from then onwards, all the other satraps acted as kings, because the family of Alexander had been destroyed.
Cassander married Thessalonice the daughter of Philippus, and survived as king for another 19 years as king, until he died of a wasting disease.
His reign, including the year in which Olympias ruled after the death of Aridaeus, lasted from the first year of the 116th Olympiad [316 B.C.] until the third year of the 120th Olympiad [298 B.C.].
