The rite which constituted a Roman citizen was participation in the Suovetaurilia, the communal sacrifice of the domestic animals, the pig, the ram, and the bull.

Since all the Roman citizens at first lived in a comparatively small area, they were all able to be present at the sacrifice.

The other states of Greece and Italy had an analogous constitution, as stated by M.Fustel de Coulanges.

It may be supposed that the Aryans were similarly divided into clans and tribes.

The word _visha,_ the substantive root of Vaishya, originally meant a clan.
