Longcase clock with calendrical, lunar, and tidal indications (The Graves Tompion). Culture: British, London. Dimensions: Overall: 77 × 17 × 8 in. (195.6 × 43.2 × 20.3 cm). Maker: Thomas Tompion (British, 1639-1713); Case attributed to Jasper Braem (active ca. 1677-ca. 1686). Date: ca. 1677-80.Tompion combined the technical advances made by English clockmakers with his own superb workmanship and ingenious designs to produce timepieces that contributed vastly to the fame of English clock making in the second half of the seventeenth century. One of Tompion's earliest surviving longcase clocks, this example was made before he began systematically numbering his works sometimeafter 1685. The dial indicates hours and minutes, subdivided into ten-second intervals (on the silvered chapter ring), calendrical information (in variouis apertures), and the phases, aspects, and ages of the moon in its monthly cycle, as well as times of high tide at London Bridge (on the central revolving disk).
