CHAP. X. THE GENS AT EOME AND IN GREECE. 143 A little later another branch took the surname of Rufus, which it replaced afterwards by that of Sylla. The Lentiili do not appear till the tirae of the Samnite wars, the Cethegi not until the second Punic war. It is the same with the Claudian gens. The Claudii remained a long time united in a single family, and all bore tho surname of Sabinus or of Regillensis, a sign of their origin. We follow them for seven generations without seeing any branches formed in this family, although it had become very numerous.

It might either comprise only a single line, or produce several branches; it was always but one family. Besides, it is easy to account for the formation of the antique gens and for its nature, if we but refer to the old belief and to the old institutions that we hav^ already described.
