For the first time, a key work in artistic historiography is presented in Spanish, which is at the root of some of the main currents that have marked the development of the discipline in the last century, from Panofsky's iconology to modern Studies. Visuals. Mnemosyne is the great project to which Aby Warburg dedicated the last years of his life and which was to summarize and crown all of his work. To do this, he compiled some 2,000 images articulated in 60 tables in a magnificent atlas that remained unfinished at his death. Despite the interest it had aroused among its contemporaries and the attempts carried out by the collaborators of the Warburg Library after its move to London, the material did not see the light until the edition of the Akademie Verlag carried out by Martin Warnke , one of the most prestigious art historians of recent decades. This edition, which scrupulously respects the work as Warburg left it, is the one that is included in the book that the reader now has in his hands. Furthermore, the Spanish version, under the supervision of Fernando Checa Cremades, includes, along with new texts written for the occasion by the aforementioned author and Karin Hellwig, several unpublished conferences by Warburg directly related to his posthumous work, which reveal the complexity and greatness of a thought that not only has not lost an iota of its interest, but is more relevant than ever.
