A fine Silesian engraved beaker of 'Koula' type, Riesengebirge (Hirschberger Tal), late 17th century Perhaps by the 'Master of the Koula Beaker', in thick-walled glass and of tapering cylindrical shape, reserved with two large oval landscape panels, one depicting Christ and St John the Baptist seated together with a lamb, a tree in the foreground and an elaborate castle on a hill in the distance, the reverse with a tree-lined river scene, perhaps the Jordan River, three figures in a small rowing boat in the foreground and a large sailing boat in the distance, a building on a clifftop to the left, the panels flanked by formal flowering plants, 11.9cm high Footnotes: The 'Master of the Koula Beaker' is a somewhat loose attribution for clearly a number of skilful engravers worked on these beakers and goblets from the end of the 17th century. Many of these are likely to have been engraved in Riesengebirge, at the Hirschberger Tal. A number of Bohemian and Silesian beakers have been linked on stylistic grounds to the celebrated 'Koula' beaker in the Museum of Decorative Arts in Prague (inv. no.30.720/1849), decorated with representations of the Five Senses.
