Figure 3.12 Illustration of the 'recurrent centripetal' Levallois technique as represented at the site of Corbehem in northern France. The diagrams illustrate how a sequence of 8 or more successive Levallois flakes can be detached from different parts of the core perimeter, with only a limited amount of intervening re-preparation of the core surface (indicated by shading) between the successive flake removals.

defined by Bordes (1950a, 1961a) and many earlier workers. Ultimately, perhaps, this is a matter of semantics. As discussed below, few workers now would dispute that most aspects of conventional disc-core techniques are essentially Levallois in all basic technological and conceptual respects. Also, as Boeda stresses, virtually all the flakes produced in the course of the core reduction sequences documented at Corbehem seem to conform to normal definitions of Levallois flakes (including the sense defined by Bordes: 1980) when assessed in terms of overall patterns and complexity of negative scar patterns on the dorsal surfaces of flakes. Even if the cores produced in the course of these strategies have many elements in common with those of conventional disc-core techniques (Fig. 3.13), the flakes produced show most of the distinctive morphological features usually regarded as fully Levallois techniques.
