The author publishes the initial fragment of an unknown treatise by Leon Battista Alberti on the casting of statues written around 1455 and preserved in cod. Ottob. lat. 1870. The fragment contains a discussion on the nature of light and the element of fire.

The Renaissance architect, moral philosopher, cryptographer, mathematician, Papal adviser, painter, city planner and land surveyor Leon Battista Alberti provided the theoretical foundations of modern perspective geometry. Alberti’s work on perspective exerted a powerful influence on painters of the stature of Albrecht Dürer, Leonardo da Vinci and Piero della Francesca. But his Della pittura of 1435–36 contains also a hitherto unrecognized ontology of pictorial projection. We sketch this ontology, and show how it can be generalized to apply to representative (...) devices in general, including maps and spatial and non-spatial databases. (shrink)

This essay develops a critical interpretation of Gadamer’s account of Renaissance painting. My point of departure is a brief reference in Truth and Method to Leon Battista Alberti, the Italian Renaissance humanist who developed an influential mathematical theory of perspective in painting. Through an explication of Gadamer’s critique of Alberti and of perspective generally, I argue that what is ultimately at stake in Gadamer’s confrontation with Alberti is Gadamer’s opposition to relativism and subjectivism and his downgrading of (...) the importance of the artistic medium for evaluating the truth-claim of an artwork. Against the theory of perspective, Gadamer contends that artworks make substantive claims to truth to which we interpretatively respond. By emphasizing this theme, our discussion resonates with contemporary “hermeneutical realism.”. (shrink)

This essay follows the fascinating mythology of grace and gift exchange to construct an argument about appearances as transcending the boundaries of things through a form of radiance or shining. The latter is based on the primary figure of the Graces, Aglaea, whose name literally signifies shining. The question arises how the obligatory rules of gift exchange—giving, receiving, and returning—apply to appearances, which leads to a cyclical “alternating current” of shining and working. It now becomes clear why the ancient Greeks (...) married the ethereal figure of Aglaea to the sweaty, clubfooted smithgod Hephaestus: shining things are necessarily linked to the making of shining things. In the magic realm of Hephaestus shining and automation are fully merged: automata are without exception made of gold or silver, while the abundantly embellished objects he creates always evoke movement. At this point in the essay the term “phenotechnology” is coined: the work of making things lies in their overworking (hypergon) which is sharply contrasted to the classic notion of ornament as parergon, as by-work, or in the words of Aby Warburg, as bewegtes Beiwerk. Instead of viewing movement as added-on (Alberti) to structure we find that the figural movement of pliant motifs in fact creates structure, a structure that according to Gottfried Semper undergoes “the mystery of transfiguration,” which reverses the relationship between surface and space: space is the very depth of radiating surfaces.

“Art”—what is it? What sort of entities are artworks? “Art”—when is it? Normally, when we visit an art exhibition, when we listen to a concert or when we look at a performing art in a setting, we use to read the titles, the tags or something textual, a threshold not crafted by the author, about the exposed or executed artworks in order to grasp their subject, style, history, and author. But: how does a title, a non-fiction depiction or a pointing, (...) and different ways of para-textual activation, entitle and unable us to such an operation and to live an aesthetic relation? This issue of “Aisthesis” explores the conditions under which it could be useful to distinguish between aesthetic objects and artworks–visual, musical, literary, performing arts– and to admit that the existence of the latter depends on a marginal and basic component of them: tags. The issue contains articles by Jerrold Levinson, Bernard Sève, Filippo Focosi, Alberto Voltolini, Giulia Alberti, Pietro Kobau, Jean-Pierre Cometti, Isabelle Thomas-Fogiel, Filippo Fimiani, Bertrand Rougé, Leardo Botti, Michel Déguy, Jean-Marie Klinkenberg, Micla Petrelli, Andrea Olivieri, Alessandro Ottaviani.
