Tiepolo dominated eighteenth-century Venetian and European painting with his monumental altarpieces, refined paintings of mythological subjects and above all with his imposing fresco decorations, which stand out for their extraordinary inventive streak and surprising liveliness and chromatic lightness. . According to a typical practice of the seventeenth and eighteenth century pictorial tradition, Tiepolo established the general lines of his compositions in sketches to be submitted to clients for preliminary approval. These small paintings also fueled a thriving collector's market, made up of amateurs who appreciated in them the freshness of the first idea and the most immediate testimony of the master's hand. The Carrara canvas is a sketch of the altarpiece created by Tiepolo for the Bergamo Cathedral in 1743.
