Rivarolo was born in Genoa in 1890. Castello graduated at a young age from the Nautical Institute of Camogli as a student engineer, then embarking on the ship "Partenope". Eclectic artist, he trained at the Polytechnic of Turin (from 1908 to 1910), also directing the magazine "Torino che ride". In 1911 his enrollment at the Brera Academy, in Milan where, among others, he met the painter Romolo Romani who was decisive in his artistic training, introducing him, also, into the environment of the futurists (Carrà nicknamed him "Verdenne" ). Meanwhile Chin Castello works as an illustrator of books and newspapers ("Corriere dei Piccoli" and "La Lettura"). We can affirm that his artistic path passes from the symbolist experience, shared also with Canegallo, with Romolo Romani, to Futurism, without forgetting the experience of aeropainting, obtaining very important results overall. His first drawings of "states of mind" date back to 1913, which give him notoriety. He participates, as a pilot, in the First World War; in 1919, after resuming his work as an illustrator, he moved to Brazil, where he remained until 1922, as a pilot instructor and, at the same time, a teacher of art history. In 1920 he exhibited in Rio de Janeiro; in 1922 he returned to Italy, resuming his collaboration with magazines and books. In 1930 he joined aeropainting and in 1938 exhibited with futurist aeropainters at the 21st Venetian Biennale. In 1942, at the 23rd Venetian Biennale, he dedicated himself to the organization of the Royal Aeronautics Pavilion, with a room dedicated to futurist aeropainters. A very important painter for Ligurian art of the twentieth century, matured through formative symbolist and futurist experiences (such as Geranzani and Canegallo), he has been re-evaluated relatively recently, and in particular with the reviews set up in 1968 at the Galleria Rotta in Genoa. , further, contribution comes in 1998 with the exhibition: "Liguria Futurista", Genoa Palazzo Ducale. Works by him are kept in Genoa, Mitchell Wolfson Jr. Collection; in London, Imperial War Museum. He died in 1960.
