1620903322Code 634A Antique barometerTorricellian mercury barometer of mahogany wood with cedar wood edges, signed Ciceri and Pini active between 1842 and 1858. Silver-plated brass dial engraved with meteorological indications. The reading of the barometer is indicated by a double hand, the first one directly connected to the barometric tube indicates the atmospheric pressure trend, the second one, operated by a turned brass knob placed under the dial, acts as a reading vernier for verifying the change in atmospheric pressure over time. Mercury alcohol thermometer with silver-plated brass temperature scale calibrated from 20 ° to 110 ° Fahrenheit. Hygrometer positioned in the upper part, spirit level recessed at the base of the barometer for the correct positioning of the instrument on the wall, with the name of the manufacturer. In the center is the convex "butler's mirror" set within a black painted mahogany frame. Height 99 cm - 38.9 inches, width 25 cm - 9.84 inches, depth / thickness 4.5 cm - 1.77 inches. Excellent condition, overhauled barometer and fully functional.

Evangelista Torricelli (1608-1647), mathematician and physicist, Galileo’s disciple, was the fist one in 1643 to make an instrument for measure changes of air pressure. Man, as farmer or navigator, has always observed and tried to forecast the changes of weather. Scientific studies about these changes began in the middle ofXVII century, following experiments about the existence of empty, that antique philosophers denied because “nature hates empty!”.
