Congrégation de l'Oratoire
Alessandro was the son of Gerolamo Vittrici (died March 1612), "sotoguardaroba" to every pope since Gregory XIII. Gerolamo commissioned the "Deposition of Christ" from Caravaggio for his uncle's chapel (the Capella della Pietà) in Santa Maria in Vallicella (the "Chiesa Nuova"), a church built for the Oratory of Saint Philip Neri.
