Shelf Clock by Seth Thomas

This shelf clock was produced by Seth Thomas (1785–1859), a clockmaker based in Connecticut, around 1820. The object is held by The Metropolitan Museum of Art (accession number 62.195). Its construction incorporates mahogany, maple, and white pine. The clock measures 27 7/8 by 15 3/4 by 3 3/4 inches (70.8 by 40 by 9.5 cm). The movement contained within the clock is derived from designs for wooden clockworks developed by Eli Terry (1772–1852). In October 1818, Thomas entered into an agreement with Terry to manufacture this shelf clock mechanism in exchange for the payment of royalty fees. Thomas went on to produce nearly five thousand movements of this type. The lower door panel of the clock features a painted scene of Mount Vernon. The clock is part of The American Wing collection at the museum.
