In the years immediately following the First World War, Sironi focused on the representation of the metropolitan landscape, portraying the Milanese suburbs in a number of drawings, sketches and oil paintings. The studies of architecture, first at the technical schools of San Pietro in Vincoli in Rome then at the engineering faculty always in the capital, constantly nourished and constituted the backbone of his poetics almost throughout the period of his activity, a poetics resolved in a meditated and rational vision made of monumentality, lights and shadows as intense as they are austere. Fields of color between a wide scale of grays and ochres - and only rarely light brushstrokes of white to illuminate the landscape - create that leaden and rarefied atmosphere that distinguishes these subjects. The suburban neighborhoods that grew out of all proportion in the years between 1900 and 1915 are rarely inhabited by human beings, whose presence is instead recalled through trams and trucks, thus approaching the all-Italian tradition of a synthetic representation that accentuates the volumes. The myth of architecture pervades all of his pictorial work: therefore, in his urban landscapes created starting from the early twenties, the composition is meditated on a clear geometry of the streets and on the volumes, so clearly closed, of the buildings, whether condominiums or industrial buildings.
