For comments see preceding no [Nos 1068 and 1069]: Degenhart and Schmitt characterise our group of drawings as belonging to the most important Middle Italian drawings of the first half of the 15th century. This applies to these very traditional model-sheets which, although they repeat earlier versions of the subjects, represent a creative and fresh attitude which had only one equivalent in Northern Italy: Pisanello. Stylistically they are closelly connected to the doublesheet in Dijon and Vienna which are also iconographically attached to Uccello´s painted oeuvre. The inscriptions on the Stockholm, dijon and Vienna drawings are by the same hand, not Uccello´s however.
