Témoignage du voyageur anglais John Evelyn (1644).
From him we went to monsieur Frene’s, who showed us many rare drawings, a Rape of Helen in black chalk ; many excellent things of Sneiders all naked ; some of Julio and Michael Angelo ; a Madonna of Passignanno ; some things of Parmensis, and other masters.
