Alexander was worshipped even in his lifetime as a god. He claimed, among other divine claims, to be a son of Ammon. In this character he is represented with the ram’s horns of that Egyptian deity on a coin of Thrace cast by Lysimachus, one of his generals and successors. [Illustration: Plate 84. PORTION OF THE EASTERN FRIEZE OF THE SARCOPHAGUS OF ALEXANDER.] Alexander was the first of mortals to have his portrait on Greek coins, and it is only in virtue of the divine honours paid to him that this is conceded even to the conqueror of the world. Many of the later kings followed his example, and portraiture on the coins now becomes common. ALEXANDRIA In studying the early civilisation of Europe, which means the history of the Mediterranean peninsulas, one must not forget that economically Egypt is the key to the whole position. In natural resources it is far the richest country in that region. Hitherto, however, it had been shut off from the rest of the world by its own peculiar civilisation and religion, though the Greeks had occasionally borrowed ideas from it and sometimes interfered in its historical course. Now Alexander gives it a Greek government and a Greek capital. In order to crush the Phœnician fleet which had been the principal naval support of the Persian Empire, he had been compelled to destroy the city of Tyre. But it was more than a strategic move. He intended the commerce and sea-power of the Levant to be henceforth in Greek hands. He succeeded brilliantly in his purpose. Phœnicia passed away from the stage of history, and only survived in her great colony of Carthage. The city of Alexandria was laid out on a mathematical plan by Greek architects. Its situation on the delta of the Nile was exceedingly favourable to commerce, especially as the difficult navigation of its waters was mitigated by the construction of a great lighthouse, one of the Seven Wonders of the World. In the division of the empire Egypt had the good fortune to fall to the share of Ptolemy, a wise and enlightened ruler, as were most of his descendants of the same name. These all pursued a policy of commerce and peaceful expansion. There was brisk traffic between Alexandria, Rhodes, Pergamum, Athens, and Syracuse, and Alexandria grew to be the greatest city in the world. It was pre-eminently Greek, but tinctured also with some of the Orientalism of its environment.
