After his academic studies in Florence and a long period of inactivity due to illness, Moroni collaborated with Adolfo De Carolis, his teacher, on the frescoes of the great hall of the University of Pisa and those for the Palazzo del Podestà in Bologna. From De Carolis he derived both the Art Nouveau inspiration and the choice of xylography as the main means of expression. As an engraver, he soon began to collaborate with the Zanichelli publishing house in Bologna, for which he produced - in addition to book covers and friezes - illustrations of classics such as the Iliad, the Odyssey and the Aeneid. Moroni was particularly appreciated as an author of woodcut ex libris, works of small and sometimes tiny format in which he demonstrated an extraordinary mastery of technique, a great capacity for synthesis and notable inventiveness. His works are preserved in museums and art galleries, libraries and private collections, starting with the Civic Museum of Forlì. In fact, his widow donated all the artistic material from Moroni's studio to the Artistic and Cultural Institutes of Forlì.
