But, even if we grant the priority, which evolutionists claim for the Old Stone Age, there are not absent even from that cultural level evident tokens of artistic genius and high intellectual gifts. Speaking of the pictures in the caves of Altamira, of Marsoulas in the Haute Garonne, and of Fonte de Gaume in the Dordogne, the archæologist Sir Arthur Evans says: “These primeval frescoes display not only consummate mastery of natural design, but an extraordinary technical resource. Apart from the charcoal used in certain outlines, the chief coloring matter was red and yellow ochre, mortars and palettes for the preparation of which have come to light. In single animals the tints varied from black to dark and ruddy brown or brilliant orange, and so, by fine gradations, to paler nuances, obtained by scraping and washing. Outlines and details are brought out by white incised lines, and the artists availed themselves with great skill of the reliefs afforded by convexities of the rock surface. But the greatest marvel of all is that such polychrome masterpieces as the bisons, standing and couchant, or with limbs huddled together, of the Altamira Cave, were executed on the ceilings of inner vaults and galleries where the light of day has never penetrated. Nowhere is there any trace of smoke, and it is clear that great progress in the art of artificial illumination had already been made. We know that stone lamps, decorated in one case with the engraved head of an ibex, were already in existence. Such was the level of artistic attainment in southwestern Europe, at a modest estimate, some 10,000 years earlier than the most ancient monuments of Egypt or Chaldæa!” (Smithson. Inst. Rpt. for 1916, pp. 429, 430.) While reaffirming our distrust of the undocumented chronology of “prehistory,” we cite these examples of palæolithic art as a proof of the fact that everywhere the manifestation of man’s physical presence coincides with the manifestation of his intelligence, and that neither in history nor in prehistory have we any evidence of the existence of a bestial or irrational man preceding _Homo sapiens_, as we know him today. It is interesting to note in this connection that a certain J. Taylor claims to have found a prehistoric engraving of a mastodon on a bone found in a rock shelter known as Jacobs’ Cavern in Missouri (cf. _Science_, Oct. 14, 1921, p. 357). Incidents of this sort must needs dampen the enthusiasm of those who are overeager to believe in the enormous antiquity of the Old Stone Age in Europe.
