”World's oldest telescope?” (på engelska). BBC News. http://news.bbc.co.uk/1/hi/sci/tech/380186.stm. Läst 1 juli 1999. ”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.”

Läst 29 juni 1999. ”Pettinato believes the lens was used by Assyrian astronomers as a telescope more than three thousand years ago. They saw more in the night sky than was possible with the naked eye alone. For example, the Assyrians saw the planet Saturn as a god surrounded by a ring of serpents. Pettinato says that would be a logical assumption to make if they saw Saturn's rings through a primitive telescope.”
