Leoncillo is the pseudonym of Leoncillo Leonardi who was an Italian sculptor. While in Rome between 1935 and 1939, he came into contact with the artists of the Roman School and realized the key to expressionist, colored ceramics with a mythological subject. From 1939 to 1942, Leoncillo established a ceramics factory in Umbertide. In 1944 he made Madre romana uccisa dai tedeschi (Rome, Coll. Terenzi), which is considered by critics to be his masterpiece. The expressionist language is developed in the sense of a plastic decomposition of the volumes that is already a prelude to post-war neocubism (Lottatori, 1946, Rome, Coll. Leonardi). In the mid-fifties he abandoned the Cubist simplification to turn to informal experiences, while retaining an extreme attention to the material used and its expressive properties (Luce perduta, 1960, Rome, Coll. Sargentini, Grande mutilazione, 1962, Rome, Coll. Leonardi).
