The maternal system of descent is found in all parts of the world where social advance stands at a certain level. This fact, added to the widespread traces the custom has left in every civilisation, warrants the assumption that mother-right in all cases preceded father-right, and has been, indeed, a stage of social growth for all branches of the human race.[102] I shall not attempt to give the numerous traces of mother-descent that are to be found in the early histories of existing civilised nations, for to do this would entail the writing of the whole chapter on this subject. For the same reason I must reluctantly pass over the abundant evidence of mother-right that is furnished in folk-lore, in heroic legends, and in the fairy stories of our children. These stories date back to a time long before written history; they are known to all of us, and belong to all countries in slightly different forms. We have regarded them as fables; they are really survivals of customs and practices once common to all society. Wherever we find a king ruling as the son of a queen, because he is the queen's husband, or because he marries a princess, we have proof of mother-descent. The influence of the mother over her son's marriage, the winning of a bride by a task done by the wooer, the brother-sister marriage so frequent in ancient mythologies, the interference of a wise woman, and the many stories of virgin-births--all are survivals of mother-right customs. Similar evidence is furnished by mother-goddesses, so often converted into Christian local saints. I wish it were possible to follow this subject,[103] whose interest offers rich rewards. Perhaps nowhere else can we gain so clear and vivid a picture as in these ancient stories and legends of the early powerful position of woman as the transmitter of inheritance and guardian of property.
