Revised from the author's dissertation presented at the Université de Lausanne. The publication is volume 4 from the series "Catalogues raisonnés d'artistes suisses". The first volume has a biographical and aesthetic study of the artist. The second contains the catalogue raisonné, which is organized by date or theme. Individual entries give number, title, inscriptions, technique and dimensions, with references to the full bibliography found in the first volume. Appendicies contain letters and texts by the artist, and a list of principal collections housing his works.
