The horse undoubtedly here stands for a time symbol, and also for the entire world. We come across in the Mithraic religion, a strange God of Time, Aion, called Kronos or Deus Leontocephalus, because his stereotyped representation is a lion-headed man, who, standing in a rigid attitude, is encoiled by a snake, whose head projects forward from behind over the lion’s head. The figure holds in each hand a key, on the chest rests a thunderbolt, upon his back are the four wings of the wind; in addition to that, the figure sometimes bears the Zodiac on his body. Additional attributes are a cock and implements. In the Carolingian psalter of Utrecht, which is based upon ancient models, the Sæculum-Aion is represented as a naked man with a snake in his hand. As is suggested by the name of the divinity, he is a symbol of time, most interestingly composed from libido symbols. The lion, the zodiac sign of the greatest summer heat,[591] is the symbol of the most mighty desire. (“My soul roars with the voice of a hungry lion,” says Mechthild of Magdeburg.) In the Mithra mystery the serpent is often antagonistic to the lion, corresponding to that very universal myth of the battle of the sun with the dragon. In the Egyptian Book of the Dead, Tum is even designated as a he-cat, because as such he fought the snake, Apophis. The encoiling also means the engulfing, the entering into the mother’s womb. Thus time is defined by the rising and setting of the sun, that is to say, through the death and renewal of the libido. The addition of the cock again suggests time, and the addition of implements suggests the creation through time. (“Durée créatrice,” Bergson.) Oromazdes and Ahriman were produced through Zrwanakarana, the “infinitely long duration.” Time, this empty and purely formal concept, is expressed in the mysteries by transformations of the creative power, the libido. Macrobius says: “Leonis capite monstratur praesens tempus—quia conditio ejus valida fervensque est.”[592] Philo of Alexandria has a better understanding: “Tempus ab hominibus pessimis putatur deus volentibus Ens essentiale abscondere—pravis hominibus tempus putatur causa rerum mundi, sapientibus vero et optimis non tempus sed Deus.”[593][594] In Firdusi[595] time is often the symbol of fate, the libido nature of which we have already learned to recognize. The Hindoo text mentioned above includes still more—its symbol of the horse contains the whole world; his kinsman and his cradle is the sea, the mother, similar to the world soul, the maternal significance of which we have seen above. Just as Aion represents the libido in an embrace, that is to say, in the state of death and of rebirth, so here the cradle of the horse is the sea, i. e. the libido is in the mother, dying and rising again, like the symbol of the dying and resurrected Christ, who hangs like ripe fruit upon the tree of life.
