This volume is a continuation of the first instalment of the editorial project Canova In Four Tempos, born in co-edition with the Pallavicino Foundation in Genoa with the goal of collecting in a refined publication the photographic research of Luigi Spina focused on the plaster models by Antonio Canova almost entirely preserved at the plaster cast gallery in Possagno. This project accompanying the four-year Canovian celebrations (2019-2022) is structured in four publications, each focused on a specific nucleus of plaster models. Its aim is to give new dignity to Antonio Canovas creative process while highlighting the fundamental role of the bronze nails (repères) that made the metamorphoses from plaster model to marble sculpture possible.
