The Musée des Confluences in Lyon, France, recently organized a remarkable exhibition: Venenum, un Monde Empoisonné. It ran from April 2017 to April 2018 and was located in one of the museum’s five large temporary exhibition spaces. Venenum did justice to the multidisciplinary and multi-thematic nature of this newly founded museum, bringing together objects otherwise classified separately as natural history, art, ethnography, or history.
