Scintillation originates from a collection of correspondence and glass photographic plates dating from the interwar period and documenting exchanges between an amateur astronomer from Neuillé-Pont-Pierre in Touraine and Gabrielle Renaudot Flammarion. Drawn from my private archives, these materials serve both as a source of research and as a central reference . Originating from Toruń and deeply rooted in the Copernican heritage of my hometown, I place Scintillation within a space of dialogue between scientific precision and poetic sensitivity, where photography becomes a tool bringing archival material into dialogue with the present.
