Un disegno agli Uffizi di Bernardo Buontalenti per il casino Mediceo di San Marco

This paper investigates the Uffizi folio 698 Orn., which contains a drawing of vases on the recto and a project for two windows on the verso. The material features of the support, the techniques of representation and the state of conservation are described. The subjects of the drawings, their attribution to Bernardo Buontalenti and dating are also discussed. The analysis focuses in particular on the verso, proposing for the first time its identification with a project by the architect for the first and ground floor windows of the central courtyard of the Casino Mediceo in Florence. Furthermore, the dating of the drawing is hypothesised in relation to its graphic style and the construction process of the building. The aim is to divulge this precious document, which testifies the work carried out by Buontalenti at San Marco both as an artistic advisor for the Grand Ducal art laboratories and as an architect. He is in fact the author of the final definition of the windows, real 'manifestos' of his architectural conception.
