I recently submitted in English a proposal for a mobility grant to study XVIIIth century maps of Poland. The proposal was sadly rejected, on grounds which could by themselves be the matter of a whole story. I will pursue this work nevertheless, most likely in French, and I therefore offer here the core text of my original proposal, as an introduction to this on-going research. I’ve removed only the previsional costs section and some considerations specific to the original institution calling for applications. I’ve also added links to some of the sources and works cited.
