Greater success attended the application of Mithradates to the peoples of the east than to the kings.

It was not difficult to represent the war as a national one of the east against the west, for such it was; it might very well be made a religious war also, and the report might be spread that the object aimed at by the army of Lucullus was the temple of the Persian Nanaea or Anaitis in Elymais or the modern Luristan, the most celebrated and the richest shrine in the whole region of the Euphrates.( 17) From far and near the Asiatics flocked in crowds to the banner of the kings, who summoned them to protect the east and its gods from the impious foreigners.

But facts had shown not only that the mere assemblage of enormous hosts was of little avail, but that the troops really capable of marching and fighting were by their very incorporation in such a mass rendered useless and involved in the general ruin.

Mithradates sought above all to develop the arm which was at once weakest among the Occidentals and strongest among the Asiatics, the cavalry; in the army newly formed by him half of the force was mounted.
For the ranks of the infantry he carefully selected, out of the mass of recruits called forth or volunteering, those fit for service, and caused them to be drilled by his Pontic officers.

The considerable army, however, which soon assembled under the banner of the great- king was destined not to measure its strength with the Roman veterans on the first chance field of battle, but to confine itself to defence and petty warfare.
