The book reviewed here, Adolf Wölfli: Draftsman, Writer, Poet, Composer, edited by Elka Spoerri, comprises a series of essays documenting and providing critical commentary on all aspects of Wölfli’s vast artistic output, which included drawings, prose, poetry, and musical compositions. In addition, the book contains a very brief biography of Adolf Wölfli and a "catalogue" of his existing works. As noted in the preface by Prof. Jean-Pierre Colombo, President of the Adolf Wölfli Foundation, the essays "investigate Wölfli’s artistic work not only from an art-historical point of view but also from the perspectives of psychology, psychiatry, literature, text analysis, and musicology." In addition, Colombo notes that another aim of this volume is to "illustrate Wölfli’s pictorial work vividly and copiously...[with] 77 color plates and 111 black-and-white illustrations."
