Note 199 — THE THEOGONY.
George Chapman translation
To his own son he should bow down his strength.] Although the Romans made a distinction between Janus and Saturn they were two titles of one and the same person. The former had the remarkable characteristic of being the author of time, and the god of the new year: the latter also was looked upon as the author of time, and held in his hand a serpent, whose tail was in his mouth and formed a circle: by which emblem was denoted the renovation of the year. On their coins they were equally represented with keys in their hand and a ship near them. Janus was described with two faces: the one that of an aged man; the other that of a youthful personage. Saturn as of an uncommon age with hair white like snow: but they had a notion that he would return to infancy. He is also said to have destroyed all things: which however were restored with vast increase. Bryant.
The faces of Janus, supposed to look to the time past and that which is to come, evidently regard the æra before the flood and that after it: and the aged and youthful visage represent the old world and the new. The keys may allude to the shutting up the productions of the earth, and again opening them. The ship is the ark. The story of Saturn and the infant Jupiter involves similar allusions. The old god devouring his children significantly points to the destruction of the human race. Saturn and Jupiter seem only separate personifications of the double visage of Janus: and the infant Jupiter personifies the second infancy of Saturn. The new order of things which took place on the renovation of nature is typified in the dethronement of the aged monarch by his youthful son.
