The same rule applied to the girl. As it became evident that the period had arrived in her life-history when she was capable of the sacred duties of motherhood, she either retired into the forest, there to commune alone with her guardian spirit, or, as among the Sioux Indians, the fact was made known to the village, and a solemn feast announced by her parents. At this, some venerable priest addressed the guests, “calling attention to the sacred and mysterious manner in which nature had announced the fact that she was ready to embrace the duties of matrimony!”[248] In these ceremonies, which may be said to belong to primitive religions in all times, we recognise again the one idea which more than any other permeated all their myths and rites,—the idea of Life. It was because the boy and girl, passing to riper years, indicated the acquisition of the power to perpetuate and transmit Life, that at this age it was held necessary for them to mark the epoch by rites of the most sacred import. _4. Rites Relating to Marriage._—If the notion of life was thus the inspiration of the rites of puberty, still more potently did it control those relating to marriage. Much has been written by special students concerning the forms of primitive marriage, and much of what has been written is theory only, not supported by actual and intimate knowledge of facts. The assertion is common in works of the kind that the earliest form of marriage was no marriage at all,—mere promiscuity,—and that, later, a modified form of the same, known as “communal” marriage, prevailed. Not a single example of either of these has been known in history or in ethnology, and it is a gratuitous hypothesis only that either ever prevailed in a permanent community. What we first discern is the family, generally centred around the mother, and tracing descent through the maternal ancestors only. This is the “matriarchal” as distinguished from the “patriarchal” system, the latter being that in which the father is the centre and head of the family, and the genealogy is traced in his line. Both these forms, however, have existed, so far as we know, in wholly primitive conditions. The selection of one or the other was a matter of local accident or incident. The primitive family, held together by one or other of these ties of blood-relationship, was a close corporation. It might adopt outsiders, but after admission they were considered of the same blood and lineage. Its property was in common, its laws were laid on all, its very gods were its own. Especially, the rules relating to marriage were prescribed with rigid formality. The general practice was that the youth must seek his bride from another recognised family (gens or totem) of the tribe. To choose her from his own immediate family was a crime of such deep dye that even an Australian savage “could not consider such a thing possible”; although, in later conditions, this artificial barrier was often weakened.[249]
