Another excellent example of a true Hermes head is the fine Polykleitan one in the Museum of Fine Arts in Boston, which is a copy of a well-known type represented by the _Boboli Hermes_ in Florence and other replicas.[710] Though S. Reinach classed this head as Kresilæan,[711] its true Polykleitan character has been established,[712] even if it does not merit the praise formerly given it by Robinson, of being “easily the best extant copy of a work by Polykleitos.”[713] [Illustration: FIG. 8.—Statue of the so-called _Jason_ (_Sandal-binder_). Louvre, Paris.] The so-called _Jason_ of the Louvre and its many replicas[714] (Fig. 8) probably represent athletes in the guise of Hermes. These statues are copies of an original of the end of the fourth century B. C., when the favorite motive originated—probably with Lysippos—of representing a figure, as in this case, with one foot on a rock, bending over and tying a sandal. Since the replicas in Munich and Paris extend both arms to the right foot, while those in London and Athens extend the left arm over the breast, with the hand resting on the right knee, Klein has argued two different versions of a common type. He compares the former with figures on the west frieze of the Parthenon, the latter with the well-known relief of Nike tying her sandal, from the Nike balustrade now in the Akropolis Museum. The one type he assigns to Lysippos, the other (with both arms down) to an earlier artist. However, the proportions of both groups agree with the Lysippan canon and so we should assume only one artist. The discussion whether the figure is tying or untying the sandal is as barren as the similar one raised about the Athena from the Nike balustrade;[715] but the question as to who is represented by the type is worthy of careful consideration. The statue in the Louvre at first was believed to represent Cincinnatus called from the plough, but Winckelmann, without evidence, gave it its present name of _Jason_. In recent years it has been interpreted as Hermes tying on his sandals, his head raised to hearken to the behest of Zeus before going forth from Olympos on his duties as messenger. This interpretation was based on the description of a statue of the god by Christodoros,[716] and the fact that the type conforms with a representation of Hermes on a coin of Markianopolis in Mœsia.[717] Arndt has argued from the coin and from the motive of the statue that Hermes and not an athlete is intended; thus the inclination of the head, he thinks, is not that of an athlete looking out over the theatre, since the regard is not far off, but merely upward; the presence of the chlamys and the sandals also fits the god. He therefore refers the copies to a Hermes-type originated by Lysippos. But Froehner’s idea that they represent athletes, even if the type were invented for Hermes, is in line with our idea of the assimilation of athlete types to that of Hermes. In this connection it may be added
