7. Nephew of Antigonus, the general of Alexander, who afterwards became king of Asia. His name is first mentioned as present with his uncle at the siege of Nora in B. C. 320, when he was given up to Eumenes as a hostage for the safety of the latter during a conference with Antigonus. (Plut. Eum. 10.) At a later period we find him entrusted by his uncle with commands of importance. Thus in B. C. 315, when Antigonus was preparing to make head against the formidable coalition organized against him, he placed Ptolemy at the head of the army which was destined to carry on operations in Asia Minor against the generals of Cassander. This object the young general successfully carried out--relieved Amisus, which was besieged by Asclepiodorus, and recovered the whole satrapy of Cappadocia; after which he advanced into Bithynia, of which he compelled the king Zipoetes to join his alliance, and then occupied Ionia, from whence Seleucus withdrew on his approach. (Diod. 19.57, 60.) He next threatened Caria, which was however for a time defended by Myrmidon, the Egyptian general; but the following year Ptolemy was able to strike a decisive blow in that quarter against Eupolemus, the general of Cassander, whom he surprised and totally defeated. (Id. ib. 62, 68.) The next summer (B. C. 313) the arrival of Antigonus himself gave a decided preponderance to his arms in Asia Minor, and Ptolemy, after rendering active assistance in the sieges of Caunus and lasus, was sent with a considerable army to Greece to carry on the war there against Cassander. His successes were at first rapid : he drove out the garrisons of his adversary from Chalcis and Oropus, invaded Attica, where he compelled Demetrius of Phalerus to make overtures of submission, and then carried his arms triumphantly through Boeotia, Phocis, and Locris. Wherever he went he expelled the Macedonian garrisons, and proclaimed the liberty and independence of the several cities. After this he directed his march to the Peloponnese, where the authority of Antigonus had been endangered by the recent defection of his general Telesphorus. (Id. ib. 75, 77,78, 87.) Here he appears to have remained till the peace of 311 suspended hostilities in that quarter. But he considered that his services had not met with their due reward from Antigonus ; and when, therefore, in B. C. 310 the kings of Macedonia and Egypt were preparing to renew the war, Ptolemy suddenly abandoned the cause of his uncle and concluded a treaty with Cassander and the son of Lagus. Probably his object was to establish himself in the chief command in the Peloponnese : but the reconciliation of Polysperchon with Cassander must have frustrated this object : and on the arrival of the Egyptian king with a fleet at Cos, Ptolemy repaired from Chalcis to join him. He was received at first with the utmost favour, but soon gave offence to. his new patron by his intrigues and ambitious demonstrations, and was in consequence thrown into prison and compelled to put an end to his life by poison, B. C. 309. (Id. 20.19,27.) Schlosser has represented this general as an enthusiast in the cause of the liberty of Greece, but there seems no reason to suppose that his professions to that effect were more earnest or sincere than those of his contemporaries.
