When Aby Warburg left for the United States in September 1895, it was not foreseeable that his search for the symbolic foundations of art would become one of the most fascinating events in the history of his field. Warburg's American journey lasted only months, and his stay in the Pueblo communities only a few weeks, but in 1923 he presented his findings in the groundbreaking lecture on the "Snake Ritual". Using selected photographs, ethnologic drawings, and numerous documents, this story and picture book details a journey of discovery. It traverses a vast continent of research, showing Warburg's diverse interlocutors - from chiefs to missionaries - and especially his records of dances, ritual objects, and artworks full of symbolic representations. The documents are evidence of the emerging shift in Warburg's scholarly thinking, which would eventually lead to the cross-border cultural comparative methodology for which he is now held in worldwide esteem.
