We know from Schwartz’s[487] demonstrations, which Kuhn has recently confirmed in his academical treatise on the stages of development in the formation of Myths, that in mythical language the sun and other luminous bodies are called ‘stones.’ To the same mythic cycle belongs the circumstance that David slays his giant-foe by casting stones. And tradition[488] says that Cain killed Abel by throwing stones. But on the whole we find in the above-quoted hymn (called Jacob’s) only slight hints that can be claimed for the mythic period; for the remains of primeval hymns like that fragment were in later times so overgrown with matter derived from historical circumstances, that we must be content if we can discover what were the points of view and conceptions chiefly represented by these fragments. The reason why it is so difficult to reconstruct the old mythic view of the Hebrews concerning the Rainbow, obviously lies in the fact that it was supplanted by a later theological explanation (Gen. IX. 12–17). It is curious that the reason assigned in this later passage for the origin of the Rainbow was not able to obtain general credence, and that even Christian popular legends frequently appear to flow from ancient mythic conceptions. I will only mention an instance given by Bernhard Schmidt—the Christians in Zante call the rainbow 'the girdle, or the bow of the Virgin, τὸ ζώναρι, τὸ τόξο τῆς παναγίας.[489] § 13. Now while Jacob’s lawful wives are mythical figures homogeneous to himself, as we have seen, his collateral wives, the two concubines Zilpah and Bilhah represent figures of the ancient myth standing in a position of opposition to Jacob. The mythical character of Zilpah has been already determined, in the Seventh Section of this chapter. For this determination we had no other resource but the etymology of the name, no mythical matter having been preserved concerning this mythical figure. The case is reversed when we enquire into the meaning of Bilhah. The resource of etymology abandons us here; for, even if we assume that the abstract idea represented by the name must here be understood in a participial sense (Bilhâ=‘the Trembling, Terrified’), yet, in the want of analogous cases, the signification of the name brings us to no track worth pursuing. But, on the other hand, we fortunately have a material myth (as opposed to a mere name), relating to Bilhah: ‘Reuben went and lay with Bilhah his father’s concubine’ (Gen. XXXV. 22).
