===Levallois Core Reduction===

[[Image:Levallois Point-Animation.gif|thumb|The making of a Levallois Point]] The recognition of [[Levallois technique|''Levallois'']] as a distinct core reduction strategy dates to the late 19th Century. The term was used to describe specific flakes with certain surface attributes <!-- (de Mortillet 1883) --> that were recovered during that period in northern France. These early descriptions were purely typological and based on the morphology of the flake products themselves. However, there was never a great deal of consensus among scholars, which typological attributes could be used to identify ''Levallois'' products. Gradually, more and more emphasis was put on the idea that ''Levallois'' flakes were the products of a particular method or process of production. Indeed, F. Bordes <!-- (e.g., 1980) --> emphasised that ''Levallois'' was essentially a method and not a particular product. However, the shape and character of a ''Levallois'' blank is also thought to be "predetermined" by the elaborate ''Levallois'' core preparation process <!-- (e.g., Van Peer 1992, 1995, 1995) -->. While a shape control system undoubtedly exists for the ''Levallois'' cores, there remain a number of significant problems. Indeed, how applied force will propagate through a specific core is determined by a number of variables and not only by the will or the desire of the Middle Palaeolithic [[flintknapper]]. Fracture mechanic variables include size, shape and internal structure of a particular flint nodule, but also the mass and resilience of the hammer stone and finally the angle and force of the blow and the shape of the core's striking platform. Given the imprecision of hand-eye co-ordination <!-- (Baumler 1995) -->, a rather high probability for only partial core reduction success is very real. Not only are there a number of significant problems with defining ''Levallois'' on the basis of predetermined blanks, but there is also considerable disagreement over what set of attributes should be used to characterise a ''Levallois'' product. Furthermore, it has also been demonstrated that very different core reduction strategies can produce seemingly diagnostic ''Levallois'' blanks<!-- (e.g., Marks & Volkman 1983; Van Peer 1992, 1995, 1998; Bringmans et al. 2003, 2004) -->.
