Pietro Antonio Gualdi Lodrini (23 December 1716 â ) was an Italian painter, mainly active in Bergamo as a painter of sacred subjects during the Rococo or late-Baroque period.
He was born in Nembro, near Bergamo, and trained painting portraits under Fra Galgario. After five years he moved to Rome, where he worked under Placido Costanzi, a pupil of Benedetto Luti. Returning to Bergamo, he painted altarpieces for a number of churches in the region, including: the Chiesa del Carmine, Bergamo; the parish church of Alzano Lombardo; the parish church of Bonate Sopra; the parish church of Spirano; the parish church of Colognola; the church of Bariano; and for the bishop's chapel in Fara Gera d'Adda.
