The present cup, designed according to antique models, is a nice example of the French Empire. The cuppa is raised on a round foot decorated with vertical grooves. Half of the outside of the cup is garnished with vertical gadroons, directly above, there are three scenes with putti applied as a relief. The handle is shaped in the form of two entangled snakes. The cup is inside and outside gilt.
Empire is the French style of classicism, during the First French Empire [Napoleonic era] (1804-1815). The art form originated at the beginning of the nineteenth century and spread throughout Europe. Greek-Roman as well as Egyptian motifs were very popular under this style. Symmetrical forms were a main decorative choice. The ornaments were usually applied on the objects and not embossed or engraved.
Maker: Joseph Deviegos became master around 1783 in Paris. One still finds from time to time objects made by Deviegos in the art market. See for instance a pair of ecuelles, Christie’s auction Interiors, Paris (April 28th 2016), Lot 604.
