Trained in Rome under the guidance of the landscape painter Luigi Campovecchio from Mantua, Ronzoni met Angelica Kauffman and Antonio Canova and formed friendships with numerous artists, including Pelagio Palagi, Martin Verstappen and Hendrik Voogd.
He returned to Bergamo in 1809, working as a set designer and producing a number of urban views and landscapes, painted from life but still informed by the classical ideal.
He was appointed professor at the Carrara Academy, whose director Giuseppe Diotti was a close friend as well as an associate in professional undertakings.
Influenced from the outset by the French school of landscape painting, his work saw a shift towards a more atmospheric approach as from 1840 with the adoption of soft, hazy brushstrokes.
This mature production displays the influence of Giuseppe Canella’s models on the one hand and Piccio’s innovative painting on the other.
