"On the Gradual Solidification of Images" is a scholarly book that explores the artistic methodology of Michelangelo Merisi da Caravaggio. Caravaggio, regarded as one of the most influential figures in modern painting, revolutionized the painting techniques of his time through his innovative approach. The author, Nevenka Kroschewski, examines the prevailing assumptions about Caravaggio's working methods and questions them. She analyzes the research literature and sheds light on the various perspectives regarding Caravaggio's techniques, particularly the claim that he worked without preliminary drawings. Through a detailed examination of Seicento textual sources and the geometric structures in his paintings, the book provides a well-founded exploration of the painter's artistic practice and contributes to the discussion on the development of modern painting. The work is aimed at art historians, students, and anyone interested in the techniques and influence of Caravaggio.
