Context: Let it be said in advance: This 'ritual dominance' of females was by no means whatsoever a matriarchy, for there never existed a female aequivalent to the social structure we refer to as 'patriarchy' today. [... ] Yet, a number of the findings which 19th century ethnologists and sociologists (even socialists) based off their figments of a proto-historical global matriarchy are certainly valid, and some of these features are empirically observable in primitive peoples even today. These findings only require to be interpreted more reasonably, that is less biased to one side or the other. Thus, one is more justified in speaking of maternal rather than "matriarchal" cultural elements when addressing these socio-cultural affairs. [... ]
The cultural traits we are dealing with here, and that in the modern period have become extremely rare in this combination, may be summarised as the following:
Lineal descent was maternal, children were regarded as descendant from the mother. Property, at times also authorisations were passed down the maternal line, either from mother to daughter or from maternal uncle to the son on the sister's side of the family. Residential affairs were matrifocal, i. e. a husband joined the bride's family and he moved in with them. Both sexes were free to be promiscuous prior to marriage, whereas females were free to choose their marital spouse, they were entitled to wide-reaching rights even as wifes, and it was easy for them to get a divorce. The ritual and religious role of females was more relevant than that of males. Biological fathers were not considered related to their children, their role as educator and caretaker was held by the mother's brother who was the social father for all of her children, even if they were fathered by different men. [... ]
Having only briefly summarised the dominant social order above, none of these traits we know hint in the slightest towards the idea that the people [of the Maternal Megalith Culture] in question were at their time aware of the causal relation between sex and giving birth.
