Doctor Capitan and the Abbé Breuil were the first to discover the paintings in Les Combarelles. In an account read before the Academy of Sciences, they say: "Most frequently, the animals whose contours are indicated by a black outline, have all the surface thus circumscribed, entirely covered with red ochre. In some cases certain parts, such as the head of the urochs, seems to have been painted over with black and red together, so as to produce a brown tint. In other cases the head of the beast is black, and the rest of the body brown. This is veritable fresco painting, and the colour was usually applied after the outline had been graven in the stone. At other times some shading is added by hatching supplied after the outline had been drawn. Finally, the contours are occasionally thrown into prominence by scraping away the surface of the rock around, so as to give to the figures the appearance of being in low relief." These wall paintings are by no means unique. They have been found as well at Pair-sur-Pair in Gironde, and in the grotto of Altamira at Santillana del Mar, in the north of Spain. Still more recently an additional revelation as to the artistic skill of primeval man has been made; in a cave hitherto unexplored has been discovered actual sculpture with rounded forms, of extinct beasts. These discoveries appeared incredible, first, because it was not considered possible that paintings of such a vastly remote antiquity could remain fresh and distinguishable, and secondly, because it was not thought that paintings and sculpture could be executed in the depths of a rayless cavern, and artificial light have left no traces in a deposit of soot on the roof. But it must be remembered that these subterranean passages have been sealed up from time immemorial, and subjected to no invasion by man or beast, or to any change of air or temperature. And secondly, that the artists obtained light from melted fat in stone bowls on the floor, in which was a wick of pith; and such lamps would hardly discolour ceiling or walls. Of the genuineness of these paintings and sculptures there can be no question, from the fact that some are partly glazed over and some half obliterated by stalagmitic deposits.
