To be sure, aside from monogamy, oriental polygamy and Indo-Tibethan polyandry were known; but these three forms could not be arranged in any historical order and stood side by side without any connection. That some nations of ancient history and some savage tribes of the present day did not trace their descent to the father, but to the mother, hence considered the female lineage as alone valid; that many nations of our time prohibit intermarrying inside of certain large groups, the extent of which was not yet ascertained and that this custom is found in all parts of the globe--these facts were known, indeed, and more examples were continually collected. But nobody knew how to make use of them. Even in E. B. Taylor's "Researches into the Early History of Mankind," etc. (1865), they are only mentioned as "queer customs" together with the usage of some savage tribes to prohibit the touching of burning wood with iron, tools, and similar religious absurdities. This history of the family dates from 1861, the year of the publication of Bachofen's "Mutterrecht" (maternal law). Here the author makes the following propositions: 1. That in the beginning people lived in unrestricted sexual intercourse, which he dubs, not very felicitously, hetaerism. 2. That such an intercourse excludes any absolutely certain means of determining parentage; that consequently descent could only be traced by the female line in compliance with maternal law--and that this was universally practiced by all the nations of antiquity. 3. That consequently women as mothers, being the only well known parents of younger generations, received a high tribute of respect and deference, amounting to a complete women's rule (gynaicocracy), according to Bachofen's idea. 4. That the transition to monogamy, reserving a certain woman exclusively to one man, implied the violation of a primeval religious law (i. e., practically a violation of the customary right of all other men to the same woman), which violation had to be atoned for or its permission purchased by the surrender of the women to the public for a limited time.
