Archæologists distinguish at present three chief stages in the history of these newer Palæolithic men in Europe, and we must name these stages here. But it may be as well to note at the same time that it is a matter of the utmost difficulty to distinguish which of two deposits in different places is the older or newer. We may very well be dealing with the work of more or less contemporary and different races when we think we are dealing with successive ones. We are dealing, the reader must bear in mind, with little disconnected patches of material, a few score all together. The earliest stage usually distinguished by the experts is the _Aurignacian_ (from the grotto of Aurignac); it is characterized by very well-made flint implements, and by a rapid development of art and more particularly of statuettes and wall paintings. The most esteemed of the painted caves is ascribed to the latter part of this the first of the three subdivisions of the newer Palæolithic. The second subdivision of this period is called the _Solutrian_ (from Solutré), and is distinguished particularly by the quality and beauty of its stone implements; some of its razor-like blades are only equalled and not surpassed by the very best of the Neolithic work. They are of course unpolished, but the best specimens are as thin as steel blades and almost as sharp. Finally, it would seem, came the _Magdalenian_ (from La Madeleine) stage, in which the horse and reindeer were dwindling in numbers and the red deer coming into Europe.[38] The stone implements are smaller, and there is a great quantity of bone harpoons, spearheads, needles, and the like. The hunters of the third and last stage of the later Palæolithic Age appear to have supplemented a diminishing food supply by fishing. The characteristic art of the period consists of deep reliefs done upon bone and line engraving upon bone. It is to this period that the designs drawn round bones belong, and it has been suggested that these designs upon round bones were used to print coloured designs upon leather. Some of the workmanship on bone was extraordinarily fine. Parkyn quotes from de Mortillet, about the Reindeer Age (Magdalenian) bone needles, that they “are much superior to those of later, even historical, times, down to the Renaissance. The Romans, for example, never had needles comparable to those of the Magdalenian epoch.” [Illustration: TIME DIAGRAM SHOWING THE ESTIMATED DURATION OF THE TRUE HUMAN PERIODS. This time diagram again is on a larger scale than its predecessors. The time diagram on page 60, if it were on this scale, would be nearly 4 feet long, and the diagram of the whole geological time on page 14, between 500 and 5000 feet long (or perhaps even as much as 10,000 feet long). ]
