Placement of the Allies
Beyond the Hastati they again leave a space of fifty
feet, and there, beginning from the same base (the Principia),
and going in a parallel direction, and to the same distance
as the other blocks, they place the cavalry of the allies facing
the Hastati. Now the number of the allies, as I have stated
above, is equal to that of the legions in regard to the infantry,
though it falls below that if we omit the extraordinarii; but
that of the cavalry is double, when the third part is deducted
for service among the extraordinarii. Therefore in marking
out the camp the spaces assigned to the latter are made proportionally deeper, so that their length remains the same as
those occupied by the legions. Thus five viae are formed: note
and back to back with these cavalry are the spaces for the
infantry of the allies, the depth being proportionally increased
according to their numbers; note and these maniples face the outer
sides of the camp and the agger. In each maniple the first
tent at either end is occupied by the centurions. note Between
the fifth and sixth squadrons of cavalry, and the
fifth and sixth maniple of infantry, there is a
space of fifty left, so that another road is made across the
camp at right angles to the others and parallel to the tents
of the Tribuni, and this they call the Via Quintana, as it runs
along the fifth squadrons and maniples.
