The term ""prehistoric Europe"" refers, of course, to Europe during the period of its pre-literary history, a span covering some 700,000 years before the appearance of the art of writing on that continent. This cavil over the use of the term ""prehistoric"" is, however, almost the only fault that can be found with Professor Stern's book. It covers the history of man in Europe--as known from the sciences auxiliary to history, and from the tools, paintings, sculptures and drawings, as well as other human relics--from the time that he descended from the trees until the introduction of civilization, in the modern sense of that term, from Asia Minor into Greece. As an account of the existence of primitive man, the book is comprehensive and exact; as the story of how the elements of that account were slowly uncovered through the years, it is exciting. The ""contemporary sources"" from which Stern quotes are the artifacts of the period, reproduced in some three hundred unusually interesting line-drawings. As a whole, Prehistoric Europe is an exceptionally adroit popularization of a difficult and complex subject, suitable for the general reader as well as for the student at the secondary level.
