different times in the papal diocese of Praeneste,[19] namely, Capranica
and Cave.[20] Inscriptional evidence is not forthcoming in either place
sufficient to warrant any certainty in the matter of correspondence of
local names to those in Praeneste. Of the two, Capranica had much more
need of dependence on Praeneste than Cave. It was down through the
little valley back of Praeneste, at the head of which Capranica lay,
that her later aqueducts came. The outlet from Capranica back over the
mountains was very difficult, and the only tillable soil within reach of
that town lay to the north of Praeneste on the ridge running toward
Gallicano, and on a smaller ridge which curved around toward Tibur and
lay still closer to the mountains. In short, Capranica, which never
attained importance enough to be of any consequence, appears to have
been always dependent upon Praeneste.

But as for Cave, that is another question. Her friends were to the east,
and there was easy access into the mountains to Sublaqueum (Subiaco) and
beyond, through the splendid passes via either of the modern towns,
Genazzano or Olevano.

It is quite evident that Cave was never a large town, and it seems most
probable that she realized that an amicable understanding with Praeneste
was discreet. This is rendered almost certain by the proof of a
continuance of business relations between the two places. The greater
number of the big tombs of the sixth and fifth centuries B.C. are of a
peperino from Cave,[21] and a good deal of the tufa used in wall
construction in Praeneste is from the quarries near Cave, as Fernique
saw.[22]
