The companion figure has not equal grace. Athletically muscular, though adolescent, the body of this young man, whose hands are tied behind his back, is writhed into an attitude of vehement protest and rebellion. He raises his face with appealing pain to heaven. The head, which is only blocked out, overweighs the form, proving that Michelangelo, unlike the Greeks, did not observe a fixed canon of proportion for the human frame. This statue bears a strong resemblance in feeling and conception to the Apollo designed for Baccio Valori. There are four rough-hewn male figures, eccentrically wrought into the rock-work of a grotto in the Boboli Gardens, which have been assigned to the Tomb of Julius. This attribution involves considerable difficulties. In the first place, the scale is different, and the stride of one of them, at any rate, is too wide for the pedestals of that monument. Then their violent contortions and ponderous adult forms seem to be at variance with the spirit of the Captives. Mr. Heath Wilson may perhaps be right in his conjecture that Michelangelo began them for the sculptural decoration on the façade of S. Lorenzo. Their incompleteness baffles criticism; yet we feel instinctively that they were meant for the open air and for effect at a considerable distance. They remind us of Deucalion's men growing out of the stones he threw behind his back. We could not wish them to be finished, or to lose their wild attraction, as of primeval beings, the remnants of dim generations nearer than ourselves to elemental nature. No better specimens of Buonarroti's way of working in the marble could be chosen. Almost savage hatchings with the point blend into finer touches from the toothed chisel; and here and there the surface has been treated with innumerable smoothing lines that round it into skin and muscle. To a man who chiselled thus, marble must have yielded like softest freestone beneath his tools; and how recklessly he wrought is clear from the defective proportions of one old man's figure, whose leg below the knee is short beyond all excuse.
