Whitehouse, David (July 1, 1999). «World's oldest telescope?». BBC News. http://news.bbc.co.uk/1/hi/sci/tech/380186.stm. Ανακτήθηκε στις 10 Μαΐου 2008. «If one Italian scientist is correct then the telescope was not invented sometime in the 16th century by Dutch spectacle makers, but by ancient Assyrian astronomers nearly three thousand years earlier. According to Professor Giovanni Pettinato of the University of Rome, a rock crystal lens, currently on show in the British museum, could rewrite the history of science. He believes that it could explain why the ancient Assyrians knew so much about astronomy.»
