Pompey

For the Romans came to the attack with the moon at their backs, and since her light was close to the horizon, the shadows made by their bodies were thrown far in advance and fell upon the enemy, who were thus unable to estimate correctly the distance between themselves and their foes, but supposing that they were already at close quarters, they hurled their javelins to no purpose and hit nobody.

The Romans, seeing this, charged upon them with loud cries, and when the enemy no longer ventured to stand their ground, but fled in panic fear, they cut them down, so that many more than ten thousand of them were slain, and their camp was captured. Mithridates himself, however, at the outset, cut and charged his way through the Romans with eight hundred horsemen; but the rest were soon dispersed and he was left with three companions.

One of these was Hypsicrateia, a concubine, who always displayed a right manly spirit and extravagant daring (for which reason the king was wont to call her Hypsicrates), and at this time, mounted and accoutred like a Persian, she was neither exhausted by the long journeys, nor did she weary of caring for the king’s person and for his horse, until they came to a place called Sinora, which was full of the king’s money and treasures.

Thence Mithridates took costly raiment and distributed it to those who had flocked to him in his flight. He also gave each of his friends a deadly poison to carry with them, that no one of them might fall into the hands of the enemy against his will. From thence he set out towards Armenia on his way to Tigranes; but that monarch forbade his coming and proclaimed a reward of a hundred talents for his person; he therefore passed by the sources of the Euphrates and continued his flight through Colchis.

Pompey then invaded Armenia on the invitation of young Tigranes, who was now in revolt from his father, and who met Pompey near the river Araxes, which takes its rise in the same regions as the Euphrates, but turns towards the east and empties into the Caspian Sea.
