Not only grote , but also niebuhr , mommsen and all the other historians of classical antiquity , have come to grief over the gens .

不仅格罗特，而且尼布尔、蒙森以及迄今为止的其它一切古典历史学家，都没有解决氏族问题。

Mommsen also feels this , and hence makes the assumption : " for a lawful marriage outside the gens , it was probably necessary to have the consent , not only of the chief , but of all members of the gens . "

蒙森也感觉到了这一点，因此，他又推测道：“为了在血族以外结婚，在法律上，大概不仅需要得到掌权者的同意，而且需要得到全体氏族成员的同意。”
