In 1937 Cagli was commissioned to decorate the vestibule of the Italian pavilion at the Paris International Exposition with panels celebrating Rome since its foundation and the great Italians. The artist, with the help of Afro, creates over 200 square meters of panel painted in tempera and covered with a hand of boiling virgin wax, according to the ancient Pompeian hipusto technique. But the absolute freedom and lack of rhetoric with which Cagli interprets the subject provoke the harsh reaction of the orthodox criticism and the fascist regime which ordered the destruction of the panels, in fact carried out only minimally. In 1936 - 1937 the Roman climate had become heavy for the artist: the incipient anti-Semitic campaign had attacked him, together with the intellectuals belonging to the Galleria della Cometa, accused of defeatism and subversivism. In Paris, therefore, Cagli presents a world at sunset. The great characters, enclosed in delimited spaces like theatrical scenes and characterized by evanescent bodies and absent or bewildered expressions, emerge from the late - ancient age of decadence, a metaphor for a completely modern melancholy and existential suffering. The chromatic material, clear and sunny, in the early Thirties, is charged with a brown - blackish background. The panel exhibited here comes from the Casa Serena in Turin where the following are currently kept: Romulus, Imperatori, Colleoni, Characters of the Rianscimento, Machiavelli.
