us activity in diplomatic and military
preparations. Envoys were sent to Mithradates, rather to reconnoitre
than to attempt a serious mediation. There was a hope at the Pontic
court that Phraates king of the Parthians would be induced by the recent
considerable successes which the allies had achieved over Rome
to enter into the Pontic-Armenian alliance. To counteract this, Roman
envoys proceeded to the court of Ctesiphon; and the internal troubles,
which distracted the Armenian ruling house, came to their aid.
A son of the great-king Tigranes, bearing the same name
had rebelled against his father, either because he was unwilling
to wait for the death of the old man, or because his father's
suspicion, which had already cost several of his brothers their
lives, led him to discern his only chance of safety in open
insurrection. Vanquished by his father, he had taken refuge
with a number of Armenians of rank at the court of the Arsacid,
and intrigued against his father there. It was partly due
to his exertions, that Phraates preferred to take the reward
which was offered to him by both sides for his accession--the secured
possession of Mesopotamia--from the hand of the Romans, renewed
with Pompeius the agreement concluded with Lucullus respecting
the boundary of the Euphrates,(4) and even consented to operate
in concert with the Romans against Armenia. But the younger Tigranes
occasioned still greater mischief than that which arose out of his
promoting the alliance between the Romans and the Parthians,
for his insurrection produced a variance between the kings
Tigranes and Mithradates themselves. The great-king cherished
in secret the suspicion that Mithradates might have had a hand
in the insurrection of his grandson--Cleopatra the mother
of the younger Tigranes was the daughter of Mithradates--
and, though no open rupture took place, the good understanding
between the two monarchs was disturbed at the very moment
when it was most urgently needed.

At the same time Pompeius prosecuted his warlike preparations
with energy. The Asiatic allied and client communities were warned
to furnish the stipulated contingents. Public notices summoned
the discharged veterans of the legions of Fimbria to return
to the standards as volunteers, and by great promises and the name
of Pompeius a considerable portion of them were induced in reality
to obey the call. The whole force united under the orders
of Pompeius may have amoun
