But when the Saviour-legend sprang up--as indeed I think it must have sprung up, in tribe after tribe and people after people, independently--then, whether it sprang from the divinization of some actual man who showed the way of light and deliverance to his fellows "sitting in darkness," or whether from the personification of the tribe itself as a god, in either case the question of the hero's parentage was bound to arise. If the 'saviour' was plainly a personification of the tribe, it was obviously impossible to suppose him the son of a mortal mother. In that case--and if the tribe was generally traced in the legends to some primeval Animal or Mountain or thing of Nature--it was probably easy to think of him (the saviour) as, born out of Nature's womb, descended perhaps from that pure Virgin of the World who is the Earth and Nature, who rules the skies at night, and stands in the changing phases of the Moon, and is worshiped (as we have seen) in the great constellation Virgo. If, on the other hand, he was the divinization of some actual man, more or less known either personally or by tradition to his fellows, then in all probability the name of his mortal mother would be recognized and accepted; but as to his father, that side of parentage being, as we have said, generally very uncertain, it would be easy to suppose some heavenly Annunciation, the midnight visit of a God, and what is usually termed a Virgin-birth. There are two elements to be remembered here, as conspiring to this conclusion. One is the condition of affairs in a remote matriarchial period, when descent was reckoned always through the maternal line, and the fatherhood in each generation was obscure or unknown or commonly left out of account; and the other is the fact--so strange and difficult for us to realize--that among some very primitive peoples, like the Australian aborigines, the necessity for a woman to have intercourse with a male, in order to bring about conception and child-birth, was actually not recognized. Scientific observation had not always got as far as that, and the matter was still under the domain of Magic! (1) A Virgin-Mother was therefore a quite imaginable (not to say 'conceivable') thing; and indeed a very beautiful and fascinating thing, combining in one image the potent magic of two very wonderful words. It does not seem impossible that considerations of this kind led to the adoption of the doctrine or legend of the virgin-mother and the heavenly father among so many races and in so many localities--even without any contagion of tradition among them.
