These rare picture clocks from the late 18th and early 19th centuries, of Czech origin, represent a unique combination of historical art and masterful clockmaking. They are a magnificent example of Czech religious iconography, depicting the legend of St. John of Nepomuk, one of the most important Czech saints and patron saints. The painted scene depicts a panoramic view of historic Prague, including its iconic buildings such as St. Vitus Cathedral and Charles Bridge. An important element of the painting is probably King Wenceslas IV, who, according to legend, had John of Nepomuk tortured and thrown into the Vltava River after the priest refused to reveal the confessional secrets of Queen Sophie. Next to the king are depicted bags of money, which may symbolize either power and property disputes between secular and ecclesiastical authorities, or corruption and bribery, which may have played a role in this dramatic story. Jan Nepomuk thus became a symbol of secrecy, but his fate also reflects the broader conflict between the king and Archbishop Jan of Jenštejn. The painted image on a metal plate is rendered in a technique popular at the time and underscores the exceptional craftsmanship of the clock. Its noble appearance is enhanced by a richly decorated frame and ornamental details. The mechanical striking mechanism not only ensures regular chiming, but also adds another level of elegance and functionality to the clock. The window with a moving motif further enriches the overall aesthetics of the clock with additional symbolic and decorative elements. This historical gem is not only a perfect example of the masterful artistry of its time, but also a valuable testimony to the deep spiritual and cultural tradition of the Czech lands. A similar painted clock can be found in the collection of the Wien Museum Karlsplatz - under inventory number U 2494. H 36.8 x W 47 x D 15 cm
