The orrery is the most detailed and complex representation of the cosmos and in addition to the movement of stars,it includes movement of the sun, moon and planets, like a giant clock mechanism. Among these devices one of the oldest was an orrery by Archimedes, which Cicero speaks widely in Tusculanae Disputationes I, 63: when Roman troops sacked Syracuse in 212 BC, the consul Marcus Claudius Marcellus in Rome brought the instrument of Archimedes, who, thanks to his ability and divine intelligence that he possessed, had managed to generate the motions of planets, each so different, from a single rotation.
Because of heliocentric system theorized by Copernicus, it was possible to create mechanical antique orreries...

Brass log in the shape of a harpoon, signed T. Walker’s Patent Harpoon Ship Log A 1 London, from the second half of the 19th century. It is an ancient nautical instrument, very rare and with a characteristic shape, which measured the distance and speed of a ship. He was thrown overboard and dragged behind the ship itself; rotating thanks to its propeller, it transmitted the number of revolutions made on itself to the three dials made on an enameled metal plate placed in the center of the log; the quadrants reported measurements in miles from 0 to 100 in tens, from 0 to 10 in units, from 0 to 1 in quarters. The data was then read every hour to also derive the speed. In good condition, fully functional and mounted on a custom-made brass wooden base. Length 50 cm – 19.7 inches, propeller width 14 cm - 5.5 inches, log body diameter 4,5 cm - 1.7 inches. Shipping is insured by Lloyd's London; our gift box is free. In the past centuries the attempt to measure the speed of the ships was especially hindered by the lack of tools for the measurement of time of sufficient precision: throwing a piece of wood into the sea from the bow of a ship and measuring the time it took to get at the stern, it was possible to obtain some information on the speed of the ship, but with many errors and inaccuracies. The principle of mechanical patent log was shown to the Royal Society in 1699 by Robert Hooke, but the first model produced for commercial use was patented just in 1802 by Edward Massey, uncle of Thomas Walker, that succeeded him in business. Thomas Walker patented his first Walker log...
