The translation of Zosimus' New History offered here was printed in 1814 by W. Green and T. Chaplin in London, and was probably prepared by J.

[1.44.1] The Scythians being thus dispersed, with the loss of great part of their troops, Zenobia began to think of extending her dominion, and therefore sent Zabdas into Egypt, because Timagenes an Egyptian attempted to place Egypt under the government of the Palmyrenians. He had for this purpose raised an army of Palmyrenians, Syrians, and barbarians, to the number of seventy thousand, which was opposed by fifty thousand Egyptians. A sharp engagement ensued between them, in which the Palmyrenians had greatly the advantage. He then departed, leaving them a garrison of five thousand men.
[1.44.2] During these transactions, Probus, who had been appointed by the emperor to clear the sea of pirates, having heard of the subjugation of Egypt by the Palmyrenians, marched against them with his own forces, and with as many of the Egyptians as were averse to the Palmyrenians, and drove out their garrison. The Palmyrenians rallying with fresh forces, Probus, having levied a body of Egyptians and Africans, gained another victory, and drove tha Palmyrenians out of Egypt. But as Probus was encamped on a mountain near Babylon,note[Cairo.] thereby cutting off the passage of the enemy into Syria, Timagenes, who was well acquainted with the country, seized on the summit of the mountain with two thousand men, and attacked the Egyptians by surprize. Probus being taken with the rest killed himself.
