"Where the collar-bone fenceth off neck and breast, and where is
the most deadly spot" (W. Leaf).

As to the helmet, the best kind, in our opinion, is one of the
Boeotian pattern,[3] on the principle again, that it covers all the
parts exposed above the breastplate without hindering vision. Another
point: the corselet should be so constructed that it does not prevent
its wearer sitting down or stooping. About the abdomen and the
genitals and parts surrounding[4] flaps should be attached in texture
and in thickness sufficient to protect[5] that region.

protect the limbs."

Again, as an injury to the left hand may disable the horseman, we
would recommend the newly-invented piece of armour called the
gauntlet, which protects the shoulder, arm, and elbow, with the hand
engaged in holding the reins, being so constructed as to extend and
contract; in addition to which it covers the gap left by the corselet
under the armpit. The case is different with the right hand, which the
horseman must needs raise to discharge a javelin or strike a blow.
Here, accordingly, any part of the corselet which would hinder action

extra flaps[6] at the joints, which as the outstretched arm is raised
unfold, and as the arm descends close tight again. The arm itself,[7]
