Another drawing after the same prototype is in the Norton Simon Museum, Pasadena (Rosenberg and Brejon de Lavergnée, op. cit.), which is inscribed 'Guido Cagnacci/ Palazzo[?] Zambeccari, Bologna'. This has been traditionally connected to The Rape of Lucretia by Guido Cagnacci, now in the Accademia di San Luca, Rome (Pisani, op. cit., no. 39). Numerous versions, as well as copies, of that painting exist. Fragonard's composition, however, clearly shows Cupid and Psyche and Rosenberg and Brejon de Lavergnée suggest that it may derive from a painting by Felice Ficherelli which was also in the collection and then thought to be by Cagnacci himself (Rosenberg and Brejon de Lavergnée, op. cit.).
