DEMETBIUS IN MACEDONIA 389 passed into the hands of Ptolemy and Seleukus. New prospects however were opened to him in Macedonia by the death of Kas- sander (his brother-in-law, brother of his wife Phila) and the family feuds supervening thereupon. Philippus, eldest son of Ivassander, succeeded his father, but died of sickness after some- thing more than a year. Between the two remaining sons, An- tipater and Alexander, a sanguinary hostility broke out. Anti- pater slew his mother Thessalonike, and threatened the life of his brother, who in his turn invited aid both from Demetrius^ and from the Epirotic king Pyrrhus. Pyrrhus being ready first, marched into Macedonia, and expelled Antipater ; receiving as his recompense the territory called Tymphasa (between Epirus and Macedonia), together with Akarnania, Amphilochia, and the town of Ambrakia, which became henceforward his chief city and residence.^ Antipater sought shelter in Thrace with his father-in-laAV Lysimachus ; by whose order, however, he was presently slain. Demetrius, occupied with other matters, was more tardy in obeying the summons ; but, on entering into Mace- donia, he found himself strong enough to dispossess and kill Al exander (who had indeed invited him, but is said to have laid j train for assassinating him), and seized the Macedonian crown not without the assent of a considerable party, to whom the name and the deeds of Kasaander and his sons were alike odi- ous.^ Demetrius became thus master of Macedonia, together with the greater part of Gresce, including Athens, Megara, and much of Peloponnesus. He undertook an expedition into Boeotia, for the purpose of conquering Thebes ; in which attempt he suc- ceeded, not without a double siege of that city, which made an obstinate resistance. He left as viceroy in Boeotia the historian, Hieronymus of Kardia,^ once the attached friend and fellow-citi- Ken of Eumenes. But Greece as a whole was managed by An- tigonus (afterwards called Antigonus Goniitus) son of Deme- trius, who maintained his supremacy unshaken during all his father's lifetime; even though Demetrius was dopdved of Mai e- 1 Plutarch, Pyrrhus, 6.
