Aby Warburg was a German #art historian and #cultural theorist. He founded the concept of #iconology, advocated that there has the #culture and society background in the pictures. Warburg introduced a new study method into art history. He put a lot of time on the study and as much as possible purchased books which he needed. He even had his own #library at home. Currently, his 60,000 books are housed in the University of London, managed by the Warburg Institute.
