The tablet's delightful view of Potsdam, seen from the romantic Pompeian seat created by Prince Karl in the picturesque park of his Glienicke villa, derives from a painting executed in the 1840's by Freydanck (1811-1887). (Ill. M. Snodin, Karl Friedrich Schinkel: A Universal Man, Manchester, 1991, p. 136, no. 60. The Prince, who had visited Pompeii in his youth, built the elliptical seat in the manner of the Stibadium of Pliny's Tusculum villa, and set it above Schinkel's bacchic-lion fountain. The caryatid nymph supporting the umbrelloed roof has been portrayed by Freydanck bearing a triumphal wreath instead of Ceres' cornucopia.
Cf. I. and W. Baer, Karl Daniel Freydank, 1811-1887, Berlin 1987, pp. 141, 146-147, for a discussion on the construction of the Stibadium and a critical analysis and illustrations of Freydank's compositions
