To one who, during his fifty years of rule, had witnessed so many unexampled changes of fortune, the cause of the great-king appeared by no means lost through the defeat of Tigranocerta; whereas the position of Lucullus was very difficult, and, if peace should not now take place and the war should be judiciously continued, even in a high degree precarious.
Renewal of the War The veteran of varied experience, who stood towards the great-king almost as a father, and was now able to exercise a personal influence over him, overpowered by his energy that weak man, and induced him not only to resolve on the continuance of the war, but also to entrust Mithradates with its political and military management.

The war was now to be changed from a cabinet contest into a national Asiatic struggle; the kings and peoples of Asia were to unite for this purpose against the domineering and haughty Occidentals.

The greatest exertions were made to reconcile the Parthians and Armenians with each other, and to induce them to make common cause against Rome.

At the suggestion of Mithradates, Tigranes offered to give back to the Arsacid Phraates the God (who had reigned since 684) the provinces conquered by the Armenians-- Mesopotamia, Adiabene, the "great valleys"-- and to enter into friendship and alliance with him.

But, after all that had previously taken place, this offer could scarcely reckon on a favourable reception; Phraates preferred to secure the boundary of the Euphrates by a treaty not with the Armenians, but with the Romans, and to look on, while the hated neighbour and the inconvenient foreigner fought out their strife.
