The Historians' History of the World 04

In 312 B.C., Antigonus made great preparations, and under the command of Ptolemy, a son of his sister, sent an army into Greece, more especially into Bœotia, which was exasperated against Cassander, for having been obliged by him to give up the territory of Thebes. In conjunction with them, Ptolemy conquered Chalcis, and wherever they went, they were successful in expelling the garrisons of Cassander, who had no other city in Greece left that sided with him except Athens. But while Antigonus was victorious there, he was losing ground in other parts; and thus he found himself obliged, in 311 B.C., to conclude a peace with his opponents.

[312-308 B.C.]

In Syria, Antigonus had entrusted the supreme command against Ptolemy and Seleucus to his son Demetrius, who was then still a very young man. This Demetrius plays a very prominent part in history. He has the honour of having his life described among the biographies in Plutarch—an honour which we might reasonably grudge Demetrius, for he is a despicable person. We know him, partly from Plutarch’s biographies, and partly from a number of anecdotes in Athenæus, to have been the most unprincipled and most detestable man in existence: the acts of faithlessness which he committed against Alexander, the son of Cassander, are not the only things for which he deserves our detestation. He was also a voluptuary of the vulgarest and most abject description; the lowest crapule was the element in the filth of which he revelled; and he was quite a heartless man, who knew no friendship; the basest creatures, the companions of his lusts, were his only friends. Cassander was, after all, capable of distinguishing persons deserving of respect, as he showed in the selection of Demetrius Phalereus; and so also was Ptolemy; but we know that Demetrius Poliorcetes lived at Athens in intimacy with the most abject and abandoned persons of the time. He also showed towards his soldiers an ingratitude and a heartlessness, which are quite revolting; they were perfectly indifferent to him, and he regarded them only as his tools. They accomplished great things for him, but he always sacrificed them without any scruple, leaving to destruction on the morrow those who had saved his life the day before. In addition to this, he was a gambler, whose dull torpor could be excited only by great changes of fortune, and who staked everything upon a card. He is remarkable for his enormous good fortune: “fortune raised him beyond all conception, and then deserted him, but when he seemed entirely lost, she again held out her hand to him,” says Plutarch, in a verse which he applies to him.

Such a man would deserve no attention at all, were it not that he acted a great part, and that nature had endowed him with great abilities, especially in mechanics, according to the leaning of that age toward the mechanical sciences. In this respect, as in many others, we may compare him with a modern person, the regent Philip of Orleans, who, however, was a far better man. Demetrius was a great inventor in mechanics, and he did much for the improvement of military engineering: this is a merit which he did not unfairly assume, but he is fully entitled to his reputation in this respect. A short time before, a great impulse had been given to mechanics in the affairs of war, and machines of every description were improved. Engines, which for centuries had remained unchanged, were now, partly through the progress of mathematics, and partly through the increased wealth that could be employed upon them, improved in one year, more than they were formerly in the course of centuries.

Demetrius was eighteen years old when Antigonus commissioned him to undertake the command of an army against Ptolemy. The first attempt failed, for at Gaza he was completely defeated, and Ptolemy again took possession of Cœle-Syria. Ptolemy carried on the war in a generous spirit, for, declaring it to be a civil war between Macedonians, he set the prisoners free without ransom, whereby he gained the good will of the Macedonians. Antigonus now undertook the command himself, and Ptolemy again evacuating the towns of Cœle-Syria, ravaged them.

Peace was then concluded, but it lasted only for a short time. Cassander succeeded in inducing Ptolemy, the nephew of Antigonus, who was stationed in Bœotia, as well as another general on the Hellespont, to revolt. Yet Antigonus soon recovered those countries. In the same year Ptolemy took Cyprus and extended his power on the coast of Asia Minor.
