cheek-pieces move on a hinge, and for the sake of comfort the hero has turned them upwards. Of the three helmets in Fig. 167, the one on the ground on the right seems also to have movable cheek-pieces, but there is no nose-piece, and only a protection for the forehead, which could probably also be pushed back; the two others have stiff nose-and cheek-pieces in one with the skull cap, but the cheek-pieces are not pointed, as was usually the case in the older kind, but rounded off. (Compare also Figs. 166, 169, and 172.) There was usually also a protecting piece for the neck, as may be seen on many other pictures. Works of art show manifold ways of decorating the helmets. (Compare the helmet of Diomede in Fig. 169.) Sometimes they made them in the shape of a human face, imitating the lines of the forehead, eyebrows, etc., in bronze. Curiously enough, this mask form was sometimes transferred even to the back of the helmet, as may be seen in Fig. 177, representing the death of Memnon, where the long hair of the warrior descends below the helmet, though this may have been due to a mistake on the part of the artist; another point of interest about this helmet is its two crests. Besides these high and usually splendid helmets, the simple cap-shaped helmets were also extant in later times, and these were strengthened by ridges or plates of brass nailed on them; such is the helmet worn by Amphiaraus in Fig. 171. To prevent excessive pressure on the head, they usually wore a close-fitting cap below it, as we see in the case of Patroclus, in Fig. 170. [Illustration: FIG. 177.]
