Placement of Triarii, Principes, and Hastati

The spaces assigned to the cavalry are opposite the space between the two groups of tents belonging to the Tribuni of the two legions, at right angles to the line along which they stand, like a cross-road; and indeed the whole arrangement of the viae is like a system of cross-roads, running on either side of the blocks of tents, those of the cavalry on one side and those of the infantry on the other. The spaces assigned to the cavalry and the Triarii in each legion are back to back, with no via between them, but touching each other, looking opposite ways; and the depth of the spaces assigned to the Triarii is only half that assigned to other maniples, because their numbers are generally only half; but though the number of the men is different, the length of the space is always the same owing to the lesser depth. Next, parallel with these spaces, at a distance of fifty feet, they place the Principes facing the Triarii; and as they face the space between themselves and the Triarii, we have two more roads formed at right angles to the hundred-foot area in front of the tents of the Tribunes, and running down from it to the outer agger of the camp on the side opposite to that of the Principia, which we agreed to call the front of the camp. Behind the spaces for the Triarii and looking in the opposite direction, and touching each other, are the spaces for the Hastati. These several branches of the service (Triarii, Principes, Hastati), being each divided into ten maniples, the cross-roads between the blocks are all the same length and terminate in the front agger of the camp; towards which they cause the last maniples in the rows to face.
