Aby Warburg (1866–1929) developed a series of notes or "fragments toward a pragmatic theory of expression" beginning in 1888, and he continued to add to them for decades. They constitute the hidden structure lying behind the edifice of Warburg's scholarship. This edition offers a presentation of the original German Bruchstücke and is prefaced by Müller's competent, if rather light, introduction (in German), and is accompanied by some 1,049 textual emendations. A full Italian translation of Warburg's frammenti follows. This marks an epochal event in the history of ideas, but it remains to be seen just how accurate and well integrated this edition is, insofar as it appears before the release of Volume IV of the "official" Studienausgabe.
