Schools of art represent one of the building blocks of art history. The notion of a school of art emerged in artistic discourse and disseminated across various countries in Europe during the early modern period. Whilst a school of art essentially denotes a group of artists or artworks, it came to be configured in multiple ways, encompassing different meanings of learning, origin, style, or nation, and mediated in various forms via academies, literature, collections, markets and galleries. Moreover, it contributed to competitive debate around the hierarchy of art and artists in Europe. The ensuing fundamental instability of the notion of a school of art helped to create a pluriform panorama of both distinct and interconnected artistic traditions within the European art world. This edited collection brings together 20 articles devoted to selected case studies from the Italian peninsula, the Low Countries, France, Spain, England, the German Empire, and Russia.
