Though badly injured, it is still possible to see in this head of the so-called _Herakles_ found at Tegea, both in full view and in profile, the characteristic Skopaic expression of passion, and to discover the means by which the artist effected it. The expression is due in great measure to the upward direction of the gaze, and to the heavy overshadowing of the deep-set eyes. It is further enhanced by the contracted brow, dilated nostril, and half-open, almost panting, mouth, whose parted lips clearly disclose the teeth. The structure of the head is in keeping with the strength of character portrayed; the skull is very deep from front to back, and its framework is massive and bony; the face is broad and short and the chin is heavy; everything emphasizes the impression of a virile and muscular warrior violently engaged in the fray. The subjects of the two pedimental groups—the Kalydonian boar hunt and the battle between Achilles and Telephos—justified the expression of unrestrained violence which we see in this and the other male heads, and gave the sculptor an opportunity to represent his heroes in the excitement of action and danger. To effect this intensity of expression Skopas relied mainly on the treatment of the eye. In one of the heads (the unhelmeted one in Athens) the gaze is not turned upwards as in the _Herakles_, nor are the neck-muscles strained as in the others, and yet the expression is even more violent than in them. Thus it is the modeling of the flesh about the eye which is the real distinguishing feature of Skopas’ work. In describing the helmeted head in Athens, E. A. Gardner says: “The eyes are set very deep in their sockets, and heavily overshadowed, at their inner corners, by the strong projection of the brow, which does not, however, as in some later examples of a similar intention on the part of the artist, meet the line of the nose at an acute angle, but arches away from it in a bold curve. At the outer corners the eyes are also heavily overshadowed, here by a projecting mass of flesh or muscle which overhangs and actually hides in part the upper lid. The eyes are very wide-open—with a dilation which comes from fixing the eyes upon a distant object—and therefore suggest the far-away look associated with a passionate nature.”[2139] COMPARISON OF THE TEGEA HEADS AND THE HEAD FROM SPARTA.
