A pupil of Giuseppe Bertini at the Brera Academy, Agazzi learned, among other things, the technique of fresco painting. He competed with Virgilio Ripari in painting flowers, and he painted so many to be called Agazzi dei Fiori or il Nuovo Scrosati. Then he devoted himself to landscape. Agazzi actively participated in the exhibitions of the Permanente in Milan and at the Venice Biennale until two years before his death. He also painted the Meeting of Garibaldi with Countess Raimondi, now in the Museo del Risorgimento in Milan. He was an excellent painter fresco and left us a superb evidence in the villa of Carlo Alberto Pisani Dossi on Como lake. Agazzi was also a printmaker, influenced by Conconi in the etchings with monotypic effects; he also dealt with extreme ease the drypoint. A member of the Associazione Italiana Acquafortisti e Incisori, he exhibited his etchings and drypoints at the Esposizione d'incisione italiana in London, 1916.
