In addition to listing entries for thirty-three works under the "Complete Works" section, Villa's catalogue includes three paintings that are described as "Works attributed to the artist's youth," including the contested "Saint Praxedis." The "Young Woman Seated at a Virginal" that has been questioned by some scholars is also included under "Complete Works." The introductory essay is illustrated and includes bibliographic information, and the catalogue is followed by a documented chronology and a list of exhibition catalogues.
