Gianni Caproni, a wealthy pioneer of Italian aeronautics, very sensitive to contemporary artistic research, commissions Ciolina to two impressive works destined for his villa in Vizzola Ticino, Return from the Alps, from 1920, and Mucche grazing, from 1922. Return from the Alps, the larger of the two with its approximately seven square meters of surface, it is also the most ambitious and complex in terms of chromatic structure and composition, the latter orchestrated on a crossing of diagonals within which a theory of marching mountaineers is inserted, in the tiring descent from the pasture after the summer stay, each described in detail and physiognomically connoted, to return a typical image of the life of the Val Vigezzo familiar to the painter. Set on the road that goes from Arvogno to Toceno, Ciolina's hometown, the scene unfolds from the fulcrum of the decentralized hut in the background from which the characters parade gradually, until they reach considerable sizes in the advanced couple, in an already well-advanced September. where the green of the hills is inflamed with autumnal orange trees and the sky, which occupies almost half of the entire composition, explodes in rays enlivened by filaments of color, to then subside in slight streaks of white clouds.
