These were accompanied by the Titian brotherhood, which had to preserve and to attend to the distinctive -cultus- of the Roman Sabines,(6) and by the thirty "curial kindlers" (-flamines curiales-), instituted for the hearth of the thirty curies.

The "wolf festival" (-lupercalia-) already mentioned was celebrated for the protection of the flocks and herds in honour of the "favourable god" (-faunus-) by the Quinctian clan and the Fabii who were associated with them after the admission of the Hill-Romans, in the month of February--a genuine shepherds' carnival, in which the "Wolves" (-luperci-) jumped about naked with a girdle of goatskin, and whipped with thongs those whom they met. In like manner the community may be conceived as represented and participating in the case of other gentile worships.
To this earliest worship of the Roman community new rites were gradually added. The most important of these worships had reference to the city as newly united and virtually founded afresh by the construction of the great wall and stronghold. In it the highest and best lovis of the Capitol--that is, the genius of the Roman people--was placed at the head of all the Roman divinities, and his "kindler" thenceforth appointed, the -flamen Dialis-, formed in conjunction with the two priests of Mars the sacred triad of high-priests.
