Description
Pull, draw, attract, and captivate. The question of »tractive forces« in fourteenth-century Italian art has so far received only limited scholarly attention. Yet these forces illuminate qualities that allow us to examine production processes, materiality, and mediality, as well as motifs and their beholders, in their physical, metaphysical, technical, and aesthetic dimensions. It is not by chance, we hypothesise, that Francesco Petrarca speaks of a “force” (vis) in his Remedies for Fortune Fair and Foul (De remediis utriusque fortunae, 1350–1366) to warn his readers of the power of art – its capacity to make beholders “cling” (inhaere) to paintings and even to “capture” (capere) their intellect.
The workshop takes such »tractive forces« in an expanded sense as its point of departure, bringing art-historical analyses into dialogue with approaches from the history of science, literature, and philosophy. How are »tractive forces« modelled in Trecento works of art? Are they primarily derived from iconographic sources, or do they reveal a particular interest in tracing visible and invisible chains of effect? To what extent does this perspective allow us to consider works of art in relation to their reception? What visual strategies and technical procedures are adopted, refined, or developed to depict and generate pull and attraction? What roles do architectures, frames, and other devices (such as curtains, parapets, and grilles) play in the dynamics of attraction and distancing? Which literary, rhetorical, natural-philosophical, or moral-theological considerations underlie these dynamics?
