prisoners taken by Demetrius was the courtesan Lamia of Athens, who later became the mistress of Demetrius, as well as Leontiscus, one of Ptolemy's sons. Demetrius sent his flagship to Syria with Aristodemus of Miletus to report the victory to Antigonus. Following his defeat, Ptolemy retreated to Egypt, and Menelaus was forced to surrender Salamis and its garrison, further increasing Demetrius' strength. Demetrius then moved to take over the rest of Cyprus, taking over the garrisons into his own army as well. According to Diodorus, the total strength added to his forces thus were 16,000 infantry and 800 cavalry. Despite their rivalry, the relationship between Ptolemy and Demetrius was characterized by a mutual respect and chivalrous conduct: after the Ptolemaic victory at Gaza in spring 312 BC Ptolemy had unconditionally released the captives and baggage train of Demetrius', a gesture reciprocated by Demetrius after his success at Myus in the next year. Demetrius honoured this after Salamis as well, immediately releasing Menelaus and other relatives and friends of Ptolemy who had been captured with their personal possessions. When Ptolemy recaptured Cyprus in 295 BC, and found Demetrius' mother and children at Salamis, he again reciprocated by immediately releasing them. Impact The victory at Salamis was used by Antigonus as a suitable pretext for his own proclamation as king (basileus), the Macedonian throne having lain vacant since the murder of Alexander IV of Macedon by Cassander in 309 BC. At the same time, Demetrius was raised to co-king alongside his father. Antigonus' assumption of the royal title was followed by an attempt to eliminate Ptolemy for good in a massive, but failed, invasion of Egypt in autumn 306, and then by the celebrated, but equally unsuccessful, Siege of Rhodes by Demetrius in 305–304 BC. Finally, in 302 BC the remaining dynasts—Ptolemy, Cassander, Seleucus, and Lysimachus—having in turn assumed the royal title themselves, allied against Antigonus and defeated him in the Battle of Ipsus in 301 BC. Antigonus was killed, and his realm was broken up and divided among the victors. Demetrius survived the battle, and thanks to his large fleet managed to maintain control of a coastal and insular realm encompassing Cyprus, the Cyclades, Sidon, Tyre, Corinth, and the major cities of western Asia Minor. During the next years, Cyprus became a base of operations for Demetrius in the Levant, and for his imposition of control over Athens and southern Greece.
