The practical dimension was immediate: Apollinaire’s lawyer and friends had to mobilize to secure his release and to establish that the connection between him and Pieret did not implicate him in the Mona Lisa theft. This required navigating a French judicial system that was, at that moment, under intense public pressure to produce results on a case that had embarrassed France.
The symbolic dimension was more enduring. The arrest revealed that the Parisian art world of 1911 had not been as careful about the provenance of objects in its orbit as its cultural prestige might suggest. Pieret had stolen objects from the Louvre and sold them to Picasso. Picasso had used them, made no inquiry about how Pieret had obtained them, and continued his association with Pieret and Apollinaire afterward. These facts did not make either Apollinaire or Picasso criminals in any legally actionable sense — the examining judge found no basis for criminal charges — but they exposed a certain carelessness about the distinction between cultural heritage as public property and cultural objects as materials available for private use.
This carelessness was not unique to them. The early twentieth-century art world operated in an environment where the provenance of non-European cultural objects was especially poorly tracked, where the category of “looted” or “stolen” was not applied to many objects that had been removed from their places of origin under conditions of colonial or quasi-colonial power. The Iberian sculptures Pieret stole from the Louvre had come to France in ways that were themselves not entirely unambiguous. The legal and ethical questions around cultural property were in their early stages of formulation.
