A very large antique brass sundial beautifully engraved and signed Cadot in Paris 1742. The back records the latitudes of many cities in France as well as Rome, Madrid, Dunkirk, Warsaw, and Danzig. Original wood and leather case is lined in red velvet with a silver clasp and brass hinge. An unusually large piece, and rare to find these with a date.
Michel Cadot (worked 1718 1753) apprenticed to instrument maker Jean-Baptiste-Nicolas Delure in the Corporation des fondeurs in 1718. He became Master in the Corporation in 1720 and worked with his father-in-law, instrument maker Henry Macquart until around 1735, jointly signing instruments Macquart et Cadot Son gendre AParis (Macquart and his son-in law Cadot in Paris). Cadot worked at the Quay de lHorloge in Paris under the sign à lAstrolabe until the late 1740s, when he moved to Lyon.
He made many Butterfield type sundials as well as sectors, theodolites and rules. Unusual for the time, he typically signed his instruments with a date.Condition: Sundial in excellent condition with original patina, a few minor stains including a spot of corrosion on the back of the dial that should be easy to remedy, see photos.
