But Phoenicia and Palestine owed as much of their Hellenism (perhaps more) to another Hellenized city and another Macedonian dynasty--to Alexandria and to the Ptolemies. Because the short Maccabaean period of Palestinian history, during which a Seleucid did happen to be holding all Syria, is very well and widely known, it is apt to be forgotten that, throughout almost all other periods of the Hellenistic Age, southern Syria, that is Palestine and Phoenicia as well as Cyprus and the Levant coast right round to Pamphylia, was under the political domination of Egypt. The first Ptolemy added to his province some of these Asiatic districts and cities, and in particular Palestine and Coele-Syria, very soon after he had assumed command of Egypt, and making no secret of his intention to retain them, built a fleet to secure his end. He knew very well that if Egypt is to hold in permanency any territory outside Africa, she must be mistress of the sea. After a brief set-back at the hands of Antigonus' son, Ptolemy made good his hold when the father was dead; and Cyprus also became definitely his in 294. His successor, in whose favour he abdicated nine years later, completed the conquest of the mainland coasts right round the Levant at the expense of Seleucus' heir. In the event, the Ptolemies kept almost all that the first two kings of the dynasty had thus won until they were supplanted by Rome, except for an interval of a little more than fifty years from 199 to about 145; and even during the latter part of this period south Syria was under Egyptian influence once more, though nominally part of the tottering Seleucid realm.
