While in the country, Alexander founded, at one of the mouths of the Nile, a city called, after himself, Alexandria. The city became the meeting- place of the East and West; and its importance through many centuries attests the far-sighted wisdom of its founder.

A less worthy enterprise of the conqueror was his expedition to the oasis of Siwah, located in the Libyan desert, where were a celebrated temple and oracle of Zeus Ammon. To gratify his own vanity, as well as to impress the superstitious barbarians, Alexander desired to be declared of celestial descent. The priests of the temple, in accordance with the wish of the king, gave out that the oracle pronounced Alexander to be the son of Zeus Ammon, and the destined ruler of the world.

THE BATTLE OF ARBELA (331 B.C.).—From Egypt Alexander recommenced his march towards the Persian capital. He had received offers of peace from Darius, but to these he is said to have replied, "There cannot be two suns in the heavens." Pushing on, he crossed the Euphrates and the Tigris without opposition; but upon the plain of Arbela, not far from ancient Nineveh, he found his further advance disputed by Darius with an immense army. Again the Macedonian phalanx "cut through the ranks of the Persians as a boat cuts through the waves." The fate of Darius has been already narrated in our story of the last of the Persian kings (see p. 82).

The battle of Arbela was one of the decisive combats of history. It marked the end of the long struggle between the East and the West, between Persia and Greece, and prepared the way for the spread of Hellenic civilization over all Western Asia.

ALEXANDER AT BABYLON, SUSA, AND PERSEPOLIS.—From the field of Arbela Alexander marched south to Babylon, which opened its gates to him without opposition. Susa was next entered by the conqueror. Here he seized incredible quantities of gold and silver ($57,000,000, it is said), the treasure of the Great King.

From Susa Alexander's march was next directed to Persepolis, where he secured a treasure more than twice as great ($138,000,000) as that found at Susa. Upon Persepolis Alexander wreaked vengeance, for all Greece had suffered at the hands of the Persians. Many of the inhabitants were massacred, and others sold into slavery; while the palaces of the Persian kings were given to the flames.

Alexander, having thus overthrown the power of Darius, now began to regard himself, not only as his conqueror, but as his successor, and was thus looked upon by the Persians, He assumed the pomp and state of an Oriental monarch, and required the most obsequious homage from all who approached him. His Greek and Macedonian companions, unused to paying such servile adulation to their king, were much displeased at Alexander's conduct, and from this time on to his death, intrigues and conspiracies were being constantly formed among them against his power and life.

CONQUEST OF BACTRIA.—Urged on by an uncontrollable desire to possess himself of the most remote countries of which any accounts had ever reached him, Alexander now led his army to the north, and, after subduing many tribes that dwelt about the Caspian Sea, boldly conducted his soldiers over the snowy passes of the Hindu Kush, and descended into the fair provinces of Bactria.

During the years 329-328 B.C. Alexander conquered not only Bactria but Sogdiana, a country lying north of the Oxus. Among his captives here was a beautiful Bactrian princess, Roxana by name, who became his bride.

Alexander's stay in Sogdiana was saddened by his murder of his dearest friend Clitus, who had saved his life at the Granicus. Both were flushed with wine when the quarrel arose; after the deed, Alexander was overwhelmed with remorse.
