[307-305 B.C.]
Until now, none of the princes had assumed the title of king, but after the victory of Salamis, Antigonus took the diadem for himself and his son. Immediately afterwards, Ptolemy, Cassander, Lysimachus, and Seleucus did the same; and the years were now counted from their accession (306 B.C.): these are what are called the Macedonian Eras.
Demetrius now remained absent from Athens for a period of three or nearly four years; during this time the city was left to itself, and a hard time it was. We may easily imagine that Cassander was not idle, and endeavoured to recover Athens, which was of such importance to him. He was in possession of Panactum and Phyle, and inflicted the severest sufferings upon the city. This war must unquestionably be regarded as one of the chief causes of the terrible poverty in which we afterwards find Athens, for there can be no doubt that the whole territory was laid waste during the incursions from Panactum and Phyle. In this war, Demochares was strategus of Athens, and with her resources alone he operated against Cassander for four years in a most able manner, until Demetrius returned.
According to the order observed by Trogus Pompeius—though not according to that of Justin, who has here quite without judgment omitted many things—we now come to the expedition of Demetrius against Rhodes, one year after the unsuccessful undertaking against Egypt.
THE SIEGE OF RHODES
[305-304 B.C.]
The salted and dried fish of the Euxine were articles of great consumption in Egypt, and it was for this trade that Rhodes was the natural entrepôt. The consequence of this was, that the Rhodians and the Ptolemies were natural friends and allies, and that Rhodes would on no account separate itself from Egypt; its whole existence depended upon the commercial advantages, which even the first Ptolemy conceded to them. Rhodes, therefore, was a weak place, in which Demetrius Poliorcetes and Antigonus might attack the Egyptians; and it would have been an immense loss to Egypt, if the two princes had conquered the island, the possession of which was to them of equal importance.
Hostilities commenced by Demetrius capturing the Rhodian merchant vessels, which were sailing to Egypt; the first example in antiquity of neutral vessels being seized upon. The Rhodians paying in equal coin, captured the ships of Antigonus, who now declared this measure to be an act of open hostility; and Demetrius was commissioned to lay siege to Rhodes. While Antigonus was engaged in preparations, the Rhodians, seeing that Ptolemy’s fleet had been defeated, made an attempt to obtain peace; but the terms which were offered to them were such as to prevent their accepting them. Antigonus demanded one hundred hostages, whom he himself was to select, the right freely to use the harbour of Rhodes for his ships of war, and an unconditional alliance against Ptolemy. These terms were rejected by the Rhodians.
Demetrius then landed at Rhodes. His preparations were immense: the determination of the Rhodians to defend themselves manfully could not be doubted, and hence every effort was made to compel them by force. Demetrius appeared with two hundred ships of war, one hundred and seventy transports, and many small vessels; he is said to have embarked no less than forty thousand men, partly sailors and partly soldiers. He assembled his forces at Loryma, opposite to Rhodes, and during his passage across, the sea between Caria and Rhodes was covered with his ships. He landed without opposition, made a harbour for his ships of war, and approached with besieging engines. The whole island was in the meantime overrun, the country was laid waste, and all who had not fled into the city, were led away into slavery.
While Demetrius was thus encamped before the walls of the city, the Rhodians were making the most extraordinary preparations. Their citizens were called to arms; in their enumeration only six thousand were found capable of bearing arms, and not more than one thousand metœci and strangers, who were willing faithfully to undertake the defence. At first they do not appear to have employed mercenaries; but they allowed their slaves to take up arms, and after the close of the war they rewarded them with freedom and the franchise.
