It would be extra interesting if it included gears to calulate the planets we can’t see with the naked eye. (Neptune predicted by math and discovered September 23, 1846, Pluto February 18, 1930 by comparing photos, and Uranus misidentified as a star or comment starting 1690 and not recognized as a planet until about 1783)
“Phoenicians cooking on sand discovered glass around 3500 BCE, but it took about 5,000 years more for glass to be shaped into a lens for the first telescope.
A spectacle maker probably assembled the first telescope. Hans Lippershey (c1570-c1619) of Holland is often credited with the invention, but he almost certainly was not the first to make one. Lippershey was, however, the first to make the new device widely known.The telescope was introduced to astronomy in 1609 by the great Italian scientist Galileo Galilei, who became the first man to see the craters of the moon, and who went on to discover sunspots, the four large moons of Jupiter, and the rings of Saturn. – about.com
