[58]It seems as undesirable, therefore, to speak here of a neolithic “revolution” as it is to refer to our theme as an “urban revolution” (see below, p. 61, n. 10). Both terms, used by V. Gordon Childe, place the changes in parallelism with the “industrial revolution,” but the word “revolution” in this phrase is already used figuratively; it does not refer to an event such as the French Revolution or the Russian Revolution, but to a change of conditions. And by extending its use in this sense, an impression of violent, and especially of purposeful change is made which the facts do not suggest. [59]R. U. Sayce, _Primitive Arts and Crafts_ (Cambridge, 1933), 27 ff. [60]An attractive guess is made by V. Gordon Childe, _Man Makes Himself_ (Oxford, 1939), 87-90. For a recent discussion of the problem which accentuates our uncertainties, see André Leroi-Gourhan, _Milieu et techniques_ (Paris, 1945), 96-119. [61]_E.g._ G. Caton-Thompson and E. W.

The Braidwoods, excavating in 1948 for the Oriental Institute at Jarmo near Sulimanieh, found remains of a settlement perhaps even older than Hassuna. See p. 29, n. 9 above. [64]S.

[65]In 1923 an expedition going to Qau el Kabir in Middle Egypt found no trace of a Ptolemaic temple which Champollion, a hundred years earlier, had marked on his maps on the east bank of the Nile; the river had destroyed both the ruins and the village of Qau and subsequently cut a new bed (G. Brunton, _Qau and Badari_ [London, 1927], 2-3, Plate I). [66]Rudolf Anthes, _Die Felseninschriften von Hat Nub_ (Leipzig, 1928), 52 ff., 95 ff.
