Like the portrait, Arturo Noci's favorite genre, the nude assumes great importance in the painter's production after 1903. Thanks also to the fame he achieved thanks to authoritative clients and buyers, Noci established himself as a portraitist, participating without interruption in the most important Italian events and ester. In 1912 the artist was among the promoters of the Roman Secession, an institution built in antithesis to the now obsolete Society of Amateurs and Cultors with the intention of encouraging openings and connections in the international environment, becoming one of the undisputed ones with Camillo Innocenti and Enrico Lionne protagonists. Exposed in 1916 at the fourth and last exhibition of the Roman Secession, Mattino uses an iconography already abundantly experimented by Noci and very fashionable in those years: turned towards a window woven with yellows and oranges, a girl is sitting on a bed of wider and more disordered multicolored brushstrokes on which the green pillow and a small mirror hinted at by short touches stand out, while her bare back, sturdy but supple, collects the light of the room in a superficial warping of cold notes. The degasian pose, the sensual colors a la Bonnard and the rapid and fragmentary sign close to Toulouse Lautrec, reveal a large French and Nabis influence.
