(Gen. XLIX. 17), they are called in the Hebrew hymn of the battle of the Rain-serpent with the Sun-horse.[515] It is this same serpent that bears a ‘fiery flying serpent’ (sârâph meʿôphêph, Is. XIV. 29), i.e. the Lightning; that in common with the lightning is called the ‘Flying Serpent’ (nâchâsh bârîach, Is. XXVII. 1), for whose conqueror the Sun, the monotheistic ideas of later times substituted Jahveh ‘who with his might lashes the sea, and who with his intelligence pierces the monster (Rahab); by whose breath the heaven becomes bright, whose hand has stabbed the _flying serpent_’ (Job XXVI. 12, 13). The hissing of this flying Serpent is said in an American myth to be the Thunder; and the Lightning is called by the Algonquins an immense serpent, which God spat out.[516] The Rain itself is regarded in mythology as a serpent; the columns of water which fall in a serpentine course to the earth are called the ‘Crooked Serpent’ (nâchâsh ʿaḳallâthôn). The flying Lightning, the crooked Serpent (both livyâthân), and the great Monster in the sea, which tries to devour the Sun when he sinks into the sea in the evening, are assailed by the Sun, and the monotheistic prophet transfers the attack upon them to Jahveh (Is. XXVII. 1; compare Ps. LXXVI. 4 [3]). It is to be noted that, in speaking of night and storms, even the later poetry uses the expression that they ‘bite, wound,’ because the Serpent of darkness and tempest bites and hurts the Sun. ‘I said, Surely the darkness will bite me (yeshûphênî), and the night [will bite] the light near me’ (Ps. CXXXIX. 11); and so of the storm (Job IX. 17). Everywhere here the verb is used which is employed in Gen. III. 15 to denote that the serpent wounds the heel of the man. In these passages of poetry, therefore, we find an echo of the myth which declares that the Serpent of the storm, when victorious, bites, wounds, or even swallows down the hero of the Sun. We encounter the Rain described still more clearly as a serpent in the sacred literature of the Parsees, in the first chapter of the Vendidâd, verse 2, where it is said that Ahuramazdao created Airyana-vaêjô to be the best of all lands, whilst in opposition to his act the Deadly Aegrô mainyus created the ‘flowing serpent’ (azhim raoidhitem) and the snow. Professor Haug was the discoverer of this explanation of the _azhim raoidhitem_;[517] nevertheless he translates it ‘a powerful serpent,’ as he thinks that the word ‘flowing’ can be only understood of the ejection of the venom, or of the writer’s remembrance of a warm spring which may have existed in the land Airyana-vaêjô. It is a very obvious conjecture that the _flowing_ serpent means the Rain; the more so because it is mentioned in conjunction with Snow.[518] The last shoots of this mythological conception are discovered in the system of the Ophites, in which the serpent represents a _moist substance_.[519]
