 Relative to Lanfranco's style, Benaschi lightened the tints and attenuated the graphic prominence of the contours of the figures in order to achieve greater chromatic fusion and a more rough pictorialism.This style manifested in the frescoes of the chapel of Santa Maria la Nova ("Death of Saint Anne", "St Paul Preaching", "St Louis of Toulouse Shows the Bull of Indulgences to the People"), in the paintings of the chapel of St Michael in the church of the Santi Apostoli, then in the fresco executed in the dome of this same church (1680, with the collaboration of Orazio Frezza), and then in the Saints on the front arches of the chapel of the church of the Gerolamini (1681).Being ill he retired to live in the convent of Santa Maria delle Grazie in Caponapoli where he decorated the church with a vast cycle of frescoes executed with the help of Orazio Frezza and Giuseppe Castellano and depicting episodes from the "Life of Christ and Virgin".
