Frequently, if not generally, the first husband enjoyed conjugal and domestic rights superior to the others, was, in fact, the chief husband. The others were husbands only in a secondary and limited sense. Both these circumstances show that even in the comparatively few cases in which polyandry existed it was softened in the direction of monogamy; for the wife belonged not to several entirely independent men, but to a group united by the closest ties of blood; she was married to one family rather than to one person. And the fact that one of her consorts possessed superior marital privileges shows that she had only one husband in the full sense of the term. Some writers, e.g. McLennan (Studies in Ancient History, pp.112, sq.) have asserted that the Levirate, the custom which compelled the brother of a deceased husband to marry his widow, had its origin in polyandry.
