It is easy to understand the maiden as a symbol of the libido used in the sense of causative comparison. The snake in Paradise is usually considered as feminine, as the seductive principle in woman, and is represented as feminine by the old artists, although properly the snake has a phallic meaning. Through a similar change of meaning the snake in antiquity becomes the symbol of the earth, which on its side is always considered feminine. The bull is the well-known symbol for the fruitfulness of the sun. The bull gods in the Mithraic liturgy were called κνωθακοφύλακες, “guardians of the axis of the earth,” by whom the axle of the orb of the heavens was turned. The divine man, Mithra, also had the same attributes; he is sometimes called the “Sol invictus” itself, sometimes the mighty companion and ruler of Helios; he holds in his right hand the “bear constellation, which moves and turns the heavens.” The bull-headed gods, equally ἱεροὶ καὶ ἄλκιμοι νεανίαι with Mithra himself, to whom the attribute νεώτερος, “young one,” “the newcomer,” is given, are merely attributive components of the same divinity. The chief god of the Mithraic liturgy is himself subdivided into Mithra and Helios; the attributes of each of these are closely related to the other. Of Helios it is said: ὄψει θεὸν νεώτερον εὐειδῆ πυρινότριχα ἐν χιτῶνι λευκῷ καὶ χλαμύδι κοκκίνῃ, ἔχοντα πύρινον στέφανον.[160] Of Mithra it is said: ὄψει θεὸν ὑπερμεγέθη, φωτινὴν ἔχοντα τὴν ὄψιν, νεώτερον, χρυσοκόμαν, ἐν χιτῶνι λευκῳ καὶ χρυσῳ στεφάνῳ καὶ ἀναξυρίσι, κατέχοντα τῇ δεξιᾷ χειρὶ μόσχου ὦμόν χρύσεον, ὅς ἐστιν ἄρκτος ἡ κινοῦσα καὶ ἀντιστρέφουσα τὸν οὐρανόν, κατὰ ὥραν ἀναπολεύουσα καὶ καταπολεύουσα. ἔπειτα ὄψει αὐτοῦ ἐκ τῶν ὀμμάτων ἀστραπὰς καὶ ἐκ τοῦ σώματος ἀστέρας ἁλλομένους.[161] If we place fire and gold as essentially similar, then a great accord is found in the attributes of the two gods. To these mystical pagan ideas there deserve to be added the probably almost contemporaneous vision of Revelation: “And being turned, I saw seven golden candlesticks. And in the midst of the candlesticks[162] one like unto the son of man, clothed with a garment down to the foot, and girt about at the breasts with a golden girdle. And his head and his hair were white as white wool, white as snow, and his eyes were as a flame of fire. And his feet like unto burnished brass, as if it had been refined in a furnace; and his voice as the sound of many waters. And he had in his right hand seven stars,[163] and out of his mouth proceeded a sharp two-edged sword,[164] and his countenance was as the sun shineth in his strength.”—_Rev._ i: 12 ff. “And I looked, and beheld a white cloud, and upon the cloud I saw one sitting like unto the son of man, having on his head a golden crown, and in his hand a sharp sickle.”[165]—_Rev._ xiv: 14.
