There"s a dispute on who invented the telescope. 250 years earlier, craftsmen in venice begun making small discs of curved glass that people could support in a frame in from of their eyes to improve their vision. Because the glass discs looked like flattened lentils they were called lenses. In the summer of 1608 a dutch spectacle maker called hans lipperhey found a unique combination of two lenses one convex and one concave could make objects appear much nearer. Then two other opticians claimed to have invented the telescope before. Galileo first heard about this in the summer of 1609, when a vendor arrived from paris to sell a telescope to the republic of venice.
