“Medico, filosofo e matematico di gran dottrina et inventione, raro nel’architettura, erudito di lettere greche, che ha già composto molti libri di proprio e non alieno intelletto”, così Federico Cesi, il princeps dell’Accademia dei Lincei, presentò nel 1612 a Galileo il nuovo adepto Nicola Antonio Stigliola, conterraneo e compagno di gioventù Giordano Bruno.

Current attempts by historians of science to revise the narrative of the Scientific Revolution by using the concept of the Baroque have important implications for art history. Correspondences between baroque art and baroque science gain new complexity when the rational, epistemologically optimistic image of the New Science is put in doubt. Rather than a method of objective observation, early seventeenth‐century science and art share an acceptance of the constructed nature of reality, of human epistemological limitations and of the role of (...) passions in the observation of the world. While Caravaggio has revolutionised art precisely through his interest in questions of knowledge and sensorial perception and by his subversive transformation of Renaissance epistemological values and ideals, this article concentrates on the work of Jusepe de Ribera, who made the senses and their shortcomings a major theme of his pictorial research. Ribera's epistemology is examined in the context of contemporary Neapolitan philosophy and science. Through the confrontation of some of the Spagnoletto's paintings with the work of figures such as Giovanni Battista della Porta, Federico Cesi and particularly Colantonio Stigliola, it becomes clear that early modern Neapolitan faith in rational knowledge was more ambiguous than is sometimes assumed.
