 At the culmination of his studies, in 1857, he exhibited "Winter Morning" at the International Exhibition in Paris.A trip in Brittany and Normandy led to early contact with English landscape painting and steered Mancini’s artistic interests towards faithful depiction from life but attenuated by late-Romantic overtones in the handling of light.Until he stopped showing work at exhibitions in 1875, he focused on rural subjects, mostly drawn from the countryside in Brianza and from memories of his youthful stay in Normandy, which were favourably reviewed by critics and won him some marks of official recognition.
