The genesis of Luwians hieroglyphics : the invention of luwian hieroglyphic script

Actes de la conférence internationale "Origins of Early Writing Systems" , October 5 to 7, 2007,Peking University, BeijingConcerning the question of Luwians hieroglyphics, a certain number of debates have arisen, especially about its origin, the place and date of its manifestation. About the first point, some researchers go for a foreign origin, but most of them agree on the fact that hieroglyphics were produced by the Hittites. Nevertheless, two points still remain: the right moment the hieroglyphics become a writing system proper; the kind of relationships between Luwians hieroglyphics and cuneiforms used by Hittites. I would examine the change from a system of symbols used for administrative or commercial exchanges to the system regarded as hieroglyphic, strictly speaking. Can critiria be defined? Can processes be depicted? Can models be proposed, and be generalized and applied to other writing systems
