The Works of Josephus?. Josephus narrates how Alexander’s empire fractured among his successors — Antigonus in Asia, Seleucus in Babylon, Lysimachus on the Hellespont, Cassander in Macedonia, and Ptolemy the son of Lagus in Egypt — and how Ptolemy Soter captured Jerusalem on a Sabbath when the city’s defenders refused to take up arms, a detail Josephus cites from the Greek historian Agatharchides of Cnidus who mocked Jewish religious scruples.
