In the Grotta dei Colombi objects of the Palaeolithic age have been found.
Further discoveries have resulted in the division of the Palaeolithic Age into various epochs or sequences according to the faunas associated with the implements or the localities where found.
The first actual find of a palaeolithic implement was that of a rudely fashioned flint in a sandbank at Menchecourt in 1841 by Boucher de Perthes.
The fully authenticated remains of palaeolithic man are few, and discoveries are confined to certain areas, e.g.
Numerous isolated palaeolithic objects of the Mousterian type have been found in the neighbourhood of Rome in the quaternary gravels of the Tiber and Anio; but no certain traces of the neolithic period have come to light, as the many Pre" flint implements found sporadically round Rome pro- historic bably belong to the period which succeeded neolithic (called by Italian archaeologists the eneolithic period) inasmuch as both stone and metal (not, however, bronze, but copper) were in use.
