The goal of the Project on the Engraved Sources of Spanish Colonial Art (PESSCA) is to document the effect of European prints on Spanish Colonial Art. To reach its goal, PESSCA has been pairing colonial works of art with their engraved prototypes and posting them online. As of now, PESSCA has gathered more than five hundred of these pairings.
PESSCA aspires to lead an international collaborative effort to identify the engraved sources of Spanish Colonial Art. To support this effort, PESSCA is housed both at the University of California-Davis and at the Pontificia Universidad Católica del Perú. PESSCA also maintains this website in order to facilitate worldwide scholarly communication on the topic.
