Early modern immigrants across Europe often organized themselves in Project Panels confraternities, creating durable institutions that acted as patrons of the visual arts.The shared origin of the members of these confraternities provides a platform to discuss and compare their strategies of visual communication with the host society.It further affords the opportunity to examine how they differentiated themselves from other brotherhoods of Schiavoni/Illyrians in the competitive environments of Italian cosmopolitan and artistic centers.This essay focuses on the two 16th-century painted Bike Parts - Seatposts - Parts programs related to Schiavoni/Illyrian confraternities in Venice and Rome, executed by Vittore Carpaccio and Giovanni Guerra with assistants, respectively, and offers a new interpretative strategy of proto-national identity to elucidate their messages.
