3. Son of Lagus, and brother of Ptolemy Soter. His name does not occur among the officers or generals of Alexander during the lifetime of that monarch, though it is incidentally mentioned by Phylarchus (apud Athen. xii. p. 539d.) in terms that would seem to imply that he then already occupied a distinguished position. (See also Aelian, Ael. VH 9.3.) The first occasion on which he appears in history is in B. C. 315, when he was appointed by his brother to the chief command of the forces despatched to Cyprus, where they were destined to co-operate with the fleet of Seleucus, and with Nicocreon, king of Salamis. (Diod. 19.62.) By their combined efforts, they soon reduced all the cities of Cyprus to subjection, with the exception of Cittium; and that also, it would appear, must have ultimately submitted. Menelaus now remained in the island, which he governed with almost absolute authority, the petty princes of the several cities being deposed, imprisoned, or assassinated on the slightest symptom of disaffection. He still held the chief command in 306, when Demetrius Poliorcetes arrived in Cyprus with a powerful fleet and army. Unable to contend with this formidable antagonist in the open field, Menelaus drew together all his forces, and shut himself up within the walls of Salamis, which he prepared to defend to the utmost. But having risked an action under the walls of the town, he was defeated with much loss; and Demetrius pressed the siege with his wonted vigour. Menelaus, however, succeeded in burning his battering engines; and by the most strenuous exertions, made good his defence until the arrival of Ptolemy himself, with a powerful fleet, to the relief of the island. In the great sea-fight that ensued, Menelaus sent a squadron of sixty ships to assist Ptolemy; but though these succeeded in forcing their way out of the harbour of Salamis, they came too late to retrieve the fortune of the day; and the total defeat of the Egyptian fleet having extinguished all his hopes of succour, lie immediately afterwards surrendered the city of Salamis, with all his forces, both military and naval, into the hands of Demetrius. The conqueror, with characteristic magnanimity, sent him back to Egypt, accompanied by his friends, and carrying with him all his private property. (Diod. 19.62, 79, 20.21, 47_53; Plut. Demetr. 15-17; Just. 15.2; Paus. 1.6.6.) From this time we hear no more of Menelaus. There is a coin, attributed to him, which must have been struck during the period of his occupation of Cyprus.
