Grimaldi, named Il Bolognese from his place of birth, was a relative of the Carracci family of artists, with whom he was probably first apprenticed.
He was also an architect and having travelled to Rome, he was appointed architect to Pope Paul V and continued to receive patronage from successive popes.
He later spent two years in France working on buildings for Louis XIV and Cardinal Mazarin, during which time he painted frescoes in the Louvre.
