RESUMO
From his arrival in Italy in 1755, Winckelmann's work is infused throughout by a fundamental antinomy: reading versus seeing. This antinomy possesses for him a decidedly epistemological significance: it allows him to present himself as the father of a discipline deserving of its name, i.e., the history of art. In Geschichte der Kunst des Alterthums (1764), he claims to break with a long tradition of art discourse which had been primarily supported by ancient texts, basing his book instead on the direct observation of the artworks. The aim of this paper is to critically examine this antinomy. How does seeing relate to reading in his working method? What relationship does art history, in the empirical dimension Winckelmann wanted to give it, have to book knowledge? Winckelmann's excerpts collection provides valuable answers to these questions. Following an old scholarly tradition, Winckelmann used to write down passages of his readings, constituting a vast handwritten library of excerpts which never left him. The result of this intense excerpting practice consists in some 7,500 pages, which allow to better define the share of empirical observation and book-based knowledge in his approach to ancient art.
