Note 734 — Chapter VI · EVENTS OF THE YEAR 701.

The army was composed of seven legions, but some troops had been left at Carrhæ. The square was composed of forty-eight cohorts, or nearly five legions; the rest was probably in reserve in the square. The 4,000 cavalry and 4,000 light infantry were probably divided half to the right and half to the left of the great square, the sides of which must have been about 1,000 mètres long.
