This is the English translation of the author's 1914 "Les dessins de Pontormo; catalogue raisonné, précédé d'une étude" (Paris: É. Champion). There have been several reprintings, including the 1972 edition published by Junius Press, distributed in North America by Abner Schram. The catalogue raisonné lists authentic paintings and frescoes, attributed works, paintings attributed to Pontormo in exhibition and sales catalogues, and lost works. The Appendices include details about Pontormo's apprenticeship, documents related to his life, and the contents of his diary.
