L'un des principaux défis de tout déchiffrement consiste à déterminer quand des glyphes apparemment similaires doivent être considérés comme des variantes graphiques (allographes) d’un même signe (par exemple, a/𝑎), partageant des valeurs phonographiques et/ou sémiographiques identiques, et quand ils doivent plutôt être considérés comme des signes distincts ayant des valeurs différentes malgré leur ressemblance formelle (par exemple, minuscule <L> vs majuscule <i> : l/I).

Cette conférence vise à explorer si la résolution de cette question dépend nécessairement de l'analyse linguistique – et donc du déchiffrement lui-même – ou si, dans certains cas, une compréhension plus approfondie de la variation graphique peut dans les faits éclairer ou faciliter le processus de déchiffrement.

Dans le cadre de cette conférence, nous opérons donc une distinction entre les systèmes d'écriture déchiffrés, où cette question a été (pour l'essentiel) réglée, et les systèmes non déchiffrés, où elle reste ouverte. L'un des principaux objectifs de cette réunion est de rassembler les chercheurs qui travaillent sur les systèmes d'écriture non déchiffrés et ceux qui étudient les systèmes déchiffrés, afin de favoriser le dialogue et le partage d'idées, notamment grâce à une description plus précise et nuancée des divers phénomènes que recouvre ce que nous appelons la variation graphique.

One of the central challenges in any decipherment lies in determining when apparently similar glyphs should be understood as graphic variants (allographs) of the same sign (e.g., a/𝑎), sharing identical phonographic and/or semographic values, and when they should instead be regarded as distinct signs with different values (e.g., minuscule <L> vs. majuscule <i>: l/I).

This conference seeks to explore whether resolving this issue necessarily depends on linguistic analysis—and therefore on decipherment itself—or whether, in some cases, a deeper understanding of graphic variation can in fact inform or facilitate the process of decipherment.

A distinction can be drawn between deciphered writing systems, where this question has (mostly) been settled, and undeciphered systems, where it remains open. One of the main aims of this meeting is to bring together scholars working on undeciphered writing systems with those studying deciphered ones, fostering dialogue and shared insights—particularly through a more precise and nuanced description of the diverse phenomena encompassed by what we term graphic variation.
