Giovanni Antonio Scopoli (1723-1788) was one of the most versatile naturalists in eighteenth-century Italy. In 1785, Scopoli conceived the ambitious publication, "Deliciae florae et faunae insubricae". Appearing in installments, this included descriptions and illustrations of plants, animals and minerals found in northern Italy. Unfortunately, Scopoli's sudden death halted publication of the "Deliciae" after its third installment. Recently, a corpus of 98 paintings, in the gouache style, were discovered in the Biblioteca Universitaria of Pavia. These gouaches appear to be the basis for plates planned in future installments of the "Deliciae". Marginal notes in Scopoli's handwriting are included. Because Scopoli's plant and animal specimens have been destroyed or dispersed, these drawings are crucial for reconstructing his scientific opus. Combined with other documents, Scopoli's marginal notes also reveal his exacting standards. He criticized the way his artists had poorly rendered the scientific details of the paintings.
