History of telescopes

The credit for the invention of the telescope has been a subject of discussion. Thus, because Democritus announced that the Milky Way is composed of vast multitudes of stars, it has been maintained by some that he could only have been led to form such an opinion from actual examination with a telescope. Other passages from the Greek and Latin authors have similarly been cited to prove that the telescope was known to the ancients. But we are no more warranted in drawing such a conclusion without any evidence other than casual remarks, however sagacious, than we should be justified in stating that Seneca was in possession of the theories of Newton because he predicted that comets would one day be found to revolve in periodic orbits.
