Symbol of the collection of glasses, the crystalline glass chalice was probably commissioned by a successor of Francesco Sforza, perhaps Ludovico il Moro. Adorned with drops of red and white enamel and golden hemispheres, it bears two Sforza heraldic plaques surmounted by a golden ducal crown. In the quadripartite coat of arms we recognize the Visconti snakes and the imperial eagles. The only precious survivor of a table service for the Lords of Milan, the glass, restored to the knot in the seventeenth century, was purchased in 1900.
