Plutarch, Antony
Bernadotte Perrin, Ed.

37. And now Phraates put Hyrodes his father to death and took possession of his kingdom,¹ other Parthians ran away in great numbers, and particularly Monaeses, a man of distinction and power, who came in flight to Antony. Antony likened the fortunes of the fugitive to those of Themistocles,² compared his own abundant resources and magnanimity to those of the Persian kings, and gave him three cities, Larissa, Arethusa, and Hierapolis, which used to be called Bambycé. [2] But when the Parthian king made an offer of friendship to Monaeses, Antony gladly sent Monaeses back to him, determined to deceive Phraates with a prospect of peace, and demanding back the standards captured in the campaign of Crassus, together with such of his men as still survived. Antony himself, however, after sending Cleopatra back to Egypt, proceeded through [3] Arabia and Armenia to the place where his forces were assembled, together with those of the allied kings. These kings were very many in number, but the greatest of them all was Artavasdes, king of Armenia, who furnished six thousand horse and seven thousand foot. Here Antony reviewed his army. There were, of the Romans themselves, sixty thousand foot-soldiers, together with the cavalry classed as Roman, namely, ten thousand Iberians and Celts; of the other nations there were thirty thousand, counting alike horsemen and light-armed troops.

[4] And yet we are told that all this preparation and power, which terrified even the Indians beyond Bactria and made all Asia quiver, was made of no avail to Antony by reason of Cleopatra. For so eager was he to spend the winter with her that he began the war before the proper time, and managed everything confusedly. He was not master of his own faculties, but, as if he were under the influence of certain drugs or of magic rites, was ever looking eagerly towards her, and thinking more of his speedy return than of conquering the enemy.
