In one quarter only was this rest for a short time disturbed. During the troublous period the neighboring country of Egypt, which had recovered its freedom, and witnessed a revival of its ancient prosperity, under the Psamatik family, began once more to aspire to the possession of those provinces which, being divided off from the rest of the Asiatic continent by the impassable Syrian desert, seems politically to belong to Africa almost more than to Asia. Psamatik I., the Psammetichus of Herodotus, had commenced an aggressive war in this quarter, probably about the time that Assyria was suffering from the Median and then from the Scythian inroads. He had besieged for several years the strong Philistine town of Ashdod, which commands the coast-route from Egypt to Palestine, and was at this time a most important city. Despite a resistance which would have wearied out any less pertinacious assailant, he had persevered in his attempt, and had finally succeeded in taking the place. He had thus obtained a firm footing in Syria; and his successor was, able, starting from this vantage-ground, to overrun and conquer the whole territory. About the year B.C. 608, Neco, son of Psamatik I., having recently ascended the throne, invaded Palestine with a large army, met and defeated Josiah, king of Judah, near Megiddo in the great plain of Esdraelon, and, pressing forward through Syria to the Euphrates, attacked and took Carchemish, the strong city which guarded the ordinary passage of the river. Idumea, Palestine, Phoenicia, and Syria submitted to him, and for three years he remained in undisturbed possession of his conquest. Then, however, the Babylonians, who had received these provinces at the division of the Assyrian Empire, began to bestir themselves. Nebuchadnezzar marched to Carchemish, defeated the army of Neco, recovered all the territory to the border of Egypt, and even ravaged a portion of that country. It is probable that in this expedition he was assisted by the Medes. At any rate, seven or eight years afterwards, when the intrigues of Egypt had again created disturbances in this quarter, and Jehoiakim, the Jewish king, broke into open insurrection, the Median monarch sent a contingent, which accompanied Nebuchadnezzar into Judaea, and assisted him to establish his power firmly in South-Western Asia. This is the last act that we can ascribe to the great Median king. He can scarcely have been much less than seventy years old at this time; and his life was prolonged at the utmost three years longer. According to Herodotus, he died B.C. 593, after a reign of exactly forty years, leaving his crown to his son Astyages, whose marriage with a Lydian princess was above related.
