Low round cup in hammered silver, the bottom with... Lot 18

Low round cup in hammered silver, the bottom with umbilicus, applied in the center of a six-pointed floral cross with vermilion. It rests on a bat with a gadrooned frieze between nets. Under its edge, it bears a punch inscribed twice, representing a bunch of grapes on a vine leaf, surmounted by the letter B and bearing in the lower part the inverted letter G? The letter B for Beaune, the letter G may be the first letter of the name of the goldsmith who according to Elisabeth Reveillon in her work in competition A. de Chassey "Les orfèvres de Bourgogne", cahiers du patrimoine, n°52, Paris 1999 could be Jean GUINOT or GUILLOT installed in Beaune between 1556 and 1565. Still according to Elisabeth Reveillon, the mark dates this cup from the middle of the 16th century. Indeed, the Beaune hallmark "the Virgin and Child" was only adopted by the goldsmiths of Beaune in 1583. But the sons of Jean Guinot or Guillot, probably used the same punch as their father, seeming not to have complied with the obligation to inscribe this new punch from the Virgin to the child having continued for a few years to use their old punch D. of the cut 12 cm - D. of the bat 6,3 cm - Weight 117 g BL
