In the context of A Book Affair, the DESTE Foundation presents Codex DESTE, a special installation featuring all ninety publications that have accompanied the Foundation's exhibitions from 1983 to this day, as well as the 2000 Words series of artist’s monographs. If an art catalogue, more than simply seeing images on paper, is a transcoding in book format of the event-making experience of an art exhibition or of an artwork, the installation Codex DESTE explores the physical dimension of publications in a structured environment. This is a material inquiry with indexical fragments and documents into the constitutive role of art catalogues in the exhibitions history of the DESTE Foundation.
