Cupid's dart marks the time on a music-playing clock incorporated in this humorous painting of the Austrian 'dejeneurs dansants' recording the popularity of the waltz. While dancers waltz in an adjoining room, a young man abandons himself to the worship of Bacchus and the entertainment of his female companions. The moral of this afternoon activity is provided by comparison with a related picture-clock portraying Emperor Franz I at Work in his Study. The latter painted in 1831 by L.C. Hofmeister, plays Joseph Haydn's Das Kaiserlied (see D. Hellich, Alt-Wiener Uhren, Vienna, 1978, no. 9).
