Torquato Tasso's poetic discourses were the most important source for Poussin's theory of painting. The poet's ideas on artistic imitation, novelty, and plot structure and unity, which are exemplified in his epic La Gerusalemme liberata, proved to be fundamental to the artist's conception of narrative painting, culminating in the Israelites Gathering Manna. Offering new interpretations of his works, this book also investigates Poussin's larger literary culture and how this context illuminates the artist's response to contemporary poetic texts, especially in his mythological paintings.
