For these reasons sculpture is faced with various sources out of which it can select and elaborate its subject-matter, and which I will now review. The essentially central source is, as I have already several times indicated, the sphere of the _particular gods._ Their distinction from humanity preeminently consists in this, that as they, in respect to that which they express, appear essentially gathered up over and beyond the finitude of care and mortal passion within a blessed repose and everlasting youth, so, too, their bodily shapes are not merely purified from the finite particularity of mankind, but they are further detached from everything which would suggest the needs and necessary limitations of sensuous life, without, however, losing their vitality. We have, for example, an object of human interest in the way a mother pacifies her child. The Greek goddesses, however, are always represented as childless. Juno, according to the myth, tosses the young Hercules from her, and the Milky Way is the result. To associate a son with the majestic spouse of Zeus was beneath the dignity of the antique point of view. Even Aphrodite does not appear in sculpture as mother. Cupid is no doubt very near to her, but scarcely in the sense of her child. In the same way Jupiter is nursed by a goat, and Romulus and Remus are suckled by a wolf. Among Egyptian and Hindoo representations, on the contrary, we find many, in which deities receive mother's milk from goddesses. Among Greek goddesses the maiden form is that which is pre-eminent, this being that which to the least extent asserts the purely natural functions of the wife. The above constitutes an important contrast between classical art and romantic, in the latter of which maternal love is a leading subject. After the gods we find that sculpture deals with heroes and those figures which have both the human and animal form in their composition, such as centaurs, fauns, and satyrs.
