XLIII. While Demetrius lay dangerously ill at Pella, he very nearly lost his kingdom, as Pyrrhus invaded the country and briskly overran it as far as Edessa. However, on his recovery, Demetrius easily drove Pyrrhus out of Macedonia, and then made terms with him, because he did not wish to be entangled in a border warfare, which would interfere with the realisation of his more important projects. He meditated a colossal enterprise indeed, nothing less than the recovery of the whole of his father’s empire. His preparations were on a commensurate scale, for he had collected a force of ninety-eight thousand foot soldiers and nearly twelve thousand horse, while at Peiræus, Corinth, Chalkis, and the ports near Pella he was engaged in the construction of a fleet of five hundred ships. He himself personally superintended the works, visiting each dockyard and giving directions to the artificers; and all men were astounded not only at the number, but at the size of the vessels which were being built. Before his time no one had ever seen a ship of fifteen or sixteen banks of oars, although in later times Ptolemy Philopator built a ship of forty banks of oars, which measured two hundred and eighty cubits in length, and forty-eight cubits in height. This ship was navigated by four hundred sailors, four thousand rowers, and, besides all these, had room upon its decks for nearly three thousand soldiers. But this ship was merely for show, and differed little from a fixed building, being totally useless, and only moved with great risk and labour; whereas the beauty of the ships of Demetrius did not render them less serviceable, nor was their equipment so elaborate as to interfere with their use, but they were no less admirable for speed and strength as for greatness of size.
XLIV. When this great armament, the largest ever collected since the death of Alexander, began to menace Asia, the three princes, Ptolemy, Seleukus, and Lysimachus, formed a confederation to oppose it. They next sent a joint letter to Pyrrhus, in which they urged him to attack Macedonia, and not to pay any regard to a peace by which Demetrius had not made any engagement not to go to war with him, but had merely obtained time to attack the others first. Pyrrhus agreed to this proposal, and Demetrius, before his preparations were completed, found himself involved in a war of considerable magnitude: for Ptolemy sailed to Greece with a large fleet and caused it to revolt from Demetrius, while Lysimachus from Thrace and Pyrrhus from Epirus invaded Macedonia and ravaged the country. Demetrius left his son to command in Greece, and himself marched to attack Lysimachus, in order to free Macedonia from the enemy. He shortly, however, received the news that Pyrrhus had taken the city of Berœa, and when the Macedonians heard this, there was an end to all discipline, for the camp was full of tears and lamentations, and abuse of Demetrius. The men no longer cared to remain with him, but became eager to go away, nominally to their homes, but really to desert to Lysimachus. Demetrius upon this determined to place the greatest possible distance between Lysimachus and himself, and accordingly marched to attack Pyrrhus; reasoning that Lysimachus was a native of Macedonia, and was popular with many of the Macedonians because he had been a companion of Alexander, while he thought that the Macedonians would not prefer a foreigner like Pyrrhus to himself. However, in this expectation he was greatly deceived: for as soon as he encamped near Pyrrhus, his soldiers had a constant opportunity of admiring his personal prowess in battle, and they had from the most ancient times been accustomed to think that the best warrior is the best king. When besides this they learned how leniently Pyrrhus had dealt with the captives, as they had long been determined to transfer their allegiance from Demetrius to some one else, they now gladly agreed that it should be to Pyrrhus. At first they deserted to him secretly and few at a time; but soon the whole camp became excited and disturbed, and at last some had the audacity to present themselves before Demetrius, and bid him seek safety in flight, for the Macedonians were tired of fighting to maintain his extravagance. Compared with the harsh language held by many other Macedonians, this appeared to Demetrius to be very reasonable advice, and so proceeding to his tent, as though he were really a play-actor and not a king, he changed his theatrical cloak for one of a dark colour, and made his way out of the camp unobserved. Most of his soldiery at once betook themselves to plundering, and while they were quarrelling with one another over the spoils of the royal tent, Pyrrhus appeared, encountered no resistance, and made himself master of the camp. Pyrrhus and Lysimachus now divided between them the kingdom of Macedonia, which had for seven consecutive years been ruled by Demetrius.
XLV. After this great disaster, Demetrius retired to Kassandreia. His wife Phila was greatly grieved at his fall, and could not bear to see Demetrius a miserable fugitive and exile after having been a king. Despairing of ever seeing better days, and bitterly reflecting how far her husband’s good luck was outweighed by his misfortunes, she ended her life by poison. Now Demetrius, anxious to save what he could from the wreck of his fortunes, proceeded to Greece, and there collected his generals and forces. The verses spoken by Menelaus in Sophokles’s play—
“But ever whirling on the wheel of fate
My fortune changes, like the changing moon
That never keeps her form two nights the same.
At first she comes with flattering countenance
And fills her orb; but when she is most bright
She wanes again, and loses all her light,”
seems to express very well the strange waxing and waning of the fortunes of Demetrius, who, as in the present instance, sometimes appeared to be quite extinguished, and then burst forth again as brilliant as ever, as little by little his power increased until he was able to carry out his plans. At first he visited the various cities of Greece dressed as a private man, without any of the insignia of royalty. One of the Thebans seeing him in this guise, cleverly applied to him the verses of Euripides:
