Born into a family of actors, Maggi embarked on classical studies at his father’s wish but also took up painting at a very early age, first with the Livornese artist Vittorio Matteo Corcos in 1897 and then with Gaetano Esposito in Naples.
The crucial turning point in Maggi’s art came in 1889 with the posthumous show of work by Giovanni Segantini held by the Milanese Society of Fine Arts, which prompted a definitive shift to landscape painting of a Divisionist character.
Commercial collaboration with Alberto Grubicy until 1913 enabled Maggi to establish himself quickly as one of the leading representatives of the second generation of Divisionist painters in Italy.
He painted a repertoire of readily comprehensible mountain landscapes focusing primarily on aspects of the visual perception of the reflection of light and colour but lacking the deep spirituality of Segantini’s work.
After an interlude devoted to portrait painting in the same decade, the artist’s mature work focused on greater simplification of subject matter, mostly in landscapes.
