The war with Antiochus did not last long; for Antiochus was wise enough to confine himself to Asia, and not to extend his power further. He would not come to Europe, because he would have been unable to defend his possessions there. He therefore soon listened to proposals of peace.
No definite peace seems to have been concluded with Antigonus; he was too weak to effect anything against Macedonia, and seems to have been reasonable enough to avoid everything which might have called forth greater efforts against him.
Ptolemy endeavoured to establish his power firmly by treaties; and here our guide passes on to the history of Pyrrhus: Ptolemy tried to form alliances, renounced his claims to Egypt, became reconciled with his brother Ptolemy Philadelphus, and tried to win the friendship of Pyrrhus.
Throughout this period, Antigonus Gonatas was at war with Ptolemy Ceraunus, Antiochus Soter, and Ptolemy Philadelphus, and carried on a petty maritime war with them. But during the same period a general Greek war was carried on against him “with the aid of Egypt.” This war is mentioned only in a chapter of Justin, by means of which we must find our way by a careful interpretation; and for this reason the war has been overlooked by all who have written on the Amphictyons. It had its origin in the Amphictyony. Justin, who mentions its date, 281, however, does not call it an Amphictyonic war. The fact is that the Greeks sought a pretext for uniting their forces, in order to rid themselves of the dominion of Antigonus, and therefore engaged in a war against the Ætolians, who were allied with Antigonus.
It is not difficult to understand that, under the Amphictyonic pretext, the Spartans again obtained the assistance of the allies, and recovered the supremacy. Sparta had the supreme command of the army. Areus (or as the Latins call him, Areas), who was then king of Sparta, as well as his son Acrotatus, was very different from the earlier Spartan kings. In his reign Sparta again became a state of some importance, not through his power but through his name, and perhaps more particularly through his good fortune. The war was carried on with Egyptian money; with it Areus raised the armies which he commanded, and the wars continued for a long time. Egypt assisted with her fleet, but gave no land forces, which were furnished by Areus.
This war forms the beginning of another interference of Egypt in the affairs of Greece, for since the time when Demetrius Poliorcetes removed the garrisons of Ptolemy Soter from Corinth and Sicyon, the Egyptian kings do not seem to have interfered in the affairs of Greece. This new interference tore Greece to pieces, and owing to the subsidies which Sparta received, the power of that state rose again.
PTOLEMY CERAUNUS IN MACEDONIA
After the Amphictyonic War, Justin passes on to Ptolemy Ceraunus and the affairs of Macedonia. He reigned two years, or one year and a half, and during that period he committed crime upon crime. His sister Arsinoe, the widow of Lysimachus, was living with two sons at Cassandrea; the Macedonian princesses had such towns as places in which they resided as widows, and in which, in case of a change of dynasty, they might be safe against any hostile machinations. Cassandrea quickly rose to prosperity, and its possession had an immense charm for her brother. If Arsinoe had placed herself under the protection of Ptolemy Philadelphus, her step-brother, the latter would have had a very strong place in Macedonia, where his fleet might have been stationed, and her sons might then have placed themselves at the head of the malcontents in Macedonia, and have come forward as pretenders. The simplest way for Ptolemy Ceraunus now was to cause his sister and her sons to be murdered, and the question as to whether this should be done or not could not excite any scruples, according to the principles of that time; the only doubt was, how it should be done.
