Though differing in detail, the rendering of the hair, common to all the replicas, is a purely athletic coiffure. The argument for attributing the original to Apollo, based on the curls around the face, is of no importance, since a similar coiffure appears on many ephebe heads by various Attic masters of the same or a slightly earlier period. The hair treatment on a little-known replica of the head in the British Museum[758] gives us an additional argument in determining whether the original was an Apollo or not. On this head there are two corkscrew curls side by side just back of the ears, which are so inorganically attached and so unsuited to the style of head as to make us believe that they were added by the copyist, even if their absence in other copies were not proof enough of this fact. Apparently the copyist adopted a well-known type of athlete and tried to convert it into an Apollo by the use of this Apolline hair attribute. The only other Apolline attribute, the quiver on the copies in the Palazzo Torlonia[759] and Museo delle Terme, may have been added as a fortuitous adjunct by the copyists, who were converting an original athlete statue into one of Apollo. It may be added, also, that the quiver does not always indicate the god, as we shall see in discussing the Delian _Diadoumenos_ (Pl. 18). When we consider, therefore, the athletic pose, the massive outline and proportions, the high-arched chest, the muscular arms and thighs, the accentuation of the veins,[760] the fashion of the hair, and the relatively small size of the head, together with the presence of the boxing-thongs on the London example, it seems reasonable to conclude that in this series of copies we may see an original athlete statue, which in certain cases was later transformed into statues of Apollo. Even if the original was actually an Apollo, its proportions were far better suited to the patron of athletic exercises than to the leader of a celestial choir. An instance of the similar use of the same type of head is shown by the colossal statue of Apollo unearthed at Olympia.[761] Here we see the same coiffure as in the heads discussed, but the presence of the remnants of a lyre indubitably shows that this copy was intended for Apollo, and so it has been rightly assigned by Treu, not to the fifth, but to a later century. When long hair was no longer the fashion for athletes, a later artist might mistakenly think that the earlier plaits were genuinely Apolline, though we know that they were common to all early athletic art. Another head in the British Museum has been ably discussed by Mrs. Strong,[762] who shows that it comes from an Apollo and not from an athlete statue. It is similar to an Apollo pictured on a stater struck at Mytilene about 400 B. C.,[763] and consequently, like the statue from Olympia, it is merely an instance of the process of converting an athlete statue into that of an Apollo.
