Dear Mario Arnaldi, If I remember correctly, there is also a 16th-century sundial in a bowl on a stone pedestal in one of the gardens/courtyards of the Ducal Palace in Urbino. For more information you should try contact dr. Roberto Mantovani ([EMAIL PROTECTED]), curator of the Gabinetto di Fisica e Museo della Strumentazione Scientifica of the University of Urbino.
