In the image, bottom right corner: "Corneli cort fe."; in the lower margin: "Ant. Lafrerij. Petri de Nobilibus Formis"
After the antique Roman bronze at the Capitoline Museums. This is one of the plates from the share of Lafréry's inheritance that had gone to Francesco Duchetti and then acquired by Pietro de Nobili, hence the presence on this impression of both Lafréry's and De Nobili's name. The plate is quoted in the partnership agreement between de Nobili and Pietro Spranghers dated at 1584 as 'Il cava spina mezzana'.
