If De Fiori’s work does feature one predominant theme, that is undoubtedly the female form. In this field, the artist especially liked to do two-subject or group portraits. The peculiarity of the Masp painting, Two Girlfriends, one of the great moments of the artist’s career, is its violently expressionist nature, especially in dealing with the subjects’ faces. The exhibition held at the Pinacoteca do Estado revealed the existence of another version of the same work, equal in size, but carried out in a denser impasto technique (Ana Maria Stickel Collection, Laudanna 1997, p. 77). In both versions one detects a vague remembrance of metaphysics, perhaps unique in De Fiori’s work, which is related to a not less rare interest in the play of architectural lines that has some bearing on abstractionist tendencies. Urban Landscape dates from the early 40s and may have had a substantial influence on Menotti Del Picchia’s Skyscrapers, painted in the same decade.
