In the course of examining Roman imperial medallions and coins in connexion with a study of Roman cult images, representations of Herakles Crowning Himself, a figure which appears on the reverses of medallions of Marcus Aurelius, Lucius Verus (Plate I, 2), and Commodus (Plate I, 3), merit further comment. These reverses, whether with or without legend, exhibit identical compositions. In the centre a young, beardless Herakles stands facing, his right hand raised in the act of placing a crown on his head; his left hand, close to his left hip, holds the club upwards in the crook of the elbow. Between club and elbow, the lion's skin hangs down over the forearm to a point midway along the left leg. The head, both forepaws, and tail are clearly visible dangling below. On all the medallions the die designer has made very clear the, important point that Herakles rests his weight on the left foot, with left hip thrown out and the right foot slightly back and out, giving a pronounced bow curve to the right side of the body from foot to shoulder. To Herakles' right and slightly behind him appears an apple tree on one branch of which hang the hero's quiver and bow; to his left rear is seen a square altar, festooned with garlands and with an offering burning on the top, and in her comprehensive monograph on Roman medallions J. M. C. Toynbee suggests that ‘the picture as a whole had been inspired by some bas-relief or painting now lost to us’. The question of relating the central figure to the whole composition will be taken up in Part II, in reappraising the general problem of famous statue types in medallion compositions. For the moment we may see what further progress may be made in identifying the statue type of the young Herakles Crowning Himself.
