Accessories such as these, among which I have here, of course, only adduced the most famous examples, are an exceptional stimulus to the acuteness and learning of our professors, and carry them into a kind of commerce in trifles, which too frequently leads them out of bounds, and finds significance in things where there is really none. As an example we are assured that two famous sleeping female figures in the Vatican and the Villa Medici are representations of Cleopatra, simply because they have a bracelet in the shape of a viper, and to the vision of such archaeologists a serpent at once suggests the death of Cleopatra, much as it would suggest to a pious father of the church the original serpent who seduced Eve in Paradise. It was, however, a prevailing custom for Greek women to wear bracelets in serpent coils, and such bracelets in fact were called by that name. Consequently the just sense of Winckelmann[176] has long ago rejected this interpretation, and Visconti has finally recognized[177] them as figures of Ariadne, as she at lasts sinks to sleep after her sorrow at the departure of Theseus. Although in uncounted cases acuteness of this quality shows itself at fault in dealing with detail of this kind, and makes itself appear contemptible in its departure from such insignificant facts, yet unquestionably both research and criticism of apparently unimportant facts are necessary, because it is only thereby that we can arrive at the closer determination of a figure. Yet even here the difficulty crops up, that attributes no less than form, do not in all cases point our conclusions to one god, but may be shared in common by several. We have the vase, for example, not only associated with Jupiter, Apollo, Mercury, Aesculapius, but also with Ceres and Hygiaea. Several goddesses receive the ear of corn; we find the lily in the hand of Juno, Venus, and Hope; and even the lightning is not the exclusive possession of Zeus, for it is shared by Pallas, who on her part again does not alone carry; the Aegis, but on equal terms with Zeus, Juno, and Apollo[178]. The source of the individual deities from a general significance of less determinate character which, they share itself is associated with ancient symbols, which were appertinent to this more general and consequently more widely shared nature.
