The first catalog of works by Giuseppe Capogrossi, from the beginning to the invention of the "signs". The catalogue raisonné of works by Giuseppe Capogrossi (Rome, 1900–1972) presents for the first time all the painter’s works up to 1949—in other words, up to the birth of the sign with the works shown at the Galleria del Secolo in Rome in January 1950. Beginning from Capogrossi’s earliest paintings, executed around 1920, the catalog records in detail the artist’s path toward the development of an increasingly abstract language and the invention of his famous "signs." The catalog presents around 600 works, arranged chronologically and divided up by technique, each accompanied by detailed technical and critical information. The volume is completed by critical essays, a detailed biographical timeline, and an exhaustive bibliography, which make the catalog an essential instrument of study for scholars, experts, and art lovers.
