My project investigates the construction and representation of aristocratic masculinity and patriarchal power. Adopting a dynamic model of power as generative and proliferating, I elucidate the ways in which numerous dynasties utilized chivalric imagery to challenge and position themselves among other regimes. This project, the first book-length study of masculinity in fifteenth-century Italian art, builds on the productive and lively focus on issues of gender in Italian Renaissance art of the last two decades. I extend these valuable investigations of femininity and female agency, to explore and ultimately denaturalize representations of noble masculinity. Representations of both men and women bolstered signorial authority; accordingly, I shift attention to the interdependent, inter-relational nature of gendered constructions of patriarchal power visualized through images of noble men and women.
