“The Mnemosyne Atlas” is Aby Warburg’s last project. This collection of Antiquity’s Pathosformel was designed to create Denkraum – a zone for reasoning, a space for thought one requires when confronting the magic world of images. Working mainly with visual evidence, Warburg transcends the limits of academic textual discourse. This unfinished project is valuable precisely because of its non finito – the essential nature of this art history masterpiece as an open work.
