The mode of rationing the Roman armies, and the manner in which the supplies were obtained and preserved, is well shown in the extant writings of those times. Besides the allowance of wheat daily,--one to two pounds,--the Roman soldiers often received a ration of pork, mutton, legumes, cheese, oil, salt, wine, and vinegar. With the grain, a porridge-pot, a spit, the casque for a cup, and with vinegar to mix with their water,--which formed the regulation drink posea, or acetum,--they marched rapidly, and retained their extraordinary vigor in the midst of pestilential regions. Every soldier carried his own food for a given length of time, which was from eight to twenty-eight days. "_Cibo cum suo._" Hence Josephus wrote, the Roman soldier is laden like a mule. This food was always of the best quality; and the wheat was always carefully selected by a commission appointed for the purpose, as we may learn from the inscription on the column of Trajan. This wheat was not always eaten raw; but was oftener roasted, and crushed upon a stone.
"Frugesque receptas Et torrere parant flammis et frugere saxo."
With all of these arrangements and movements, there was method even as to the time of taking food. The soldier ate twice a day, and at appointed hours--at the sixth hour, "Prandium;" and at the tenth hour, "Vesperna."
