    Abstract. Several early spyglasses are depicted in five paintings by Jan Brueghel the Elder
    completed between 1608 and 1625, as he was court painter of Archduke Albert VII of
    Habsburg. An optical tube that appears in the Extensive Landscape with View of the Castle
    of Mariemont, dated 1608-1612, represents the first painting of a telescope whatsoever. We
    collected some documents showing that Albert VII obtained spyglasses very early directly
    from Lipperhey or Sacharias Janssen. Thus the painting likely reproduces one of the first
    man-made telescopes ever. Two other instruments appear in two Allegories of Sight made
    in the years 1617 and 1618. These are sophisticated instruments and the structure suggests
    that they may be keplerian, but this is about two decades ahead this mounting was in use.

    From Wiki.
    http://en.wikipedia.org/wiki/Telescope

    The earliest evidence of working telescopes were the refracting telescopes that appeared in the Netherlands in 1608. Their development is credited to three individuals: Hans Lippershey and Zacharias Janssen, who were spectacle makers in Middelburg, and Jacob Metius of Alkmaar.[4] Galileo greatly improved upon these designs the following year.

    The idea that a mirror could be used as an objective instead of a lens was being investigated soon after the invention of the refracting telescope.[5] The potential advantages of using parabolic mirrors, primarily reduction of spherical aberration with no chromatic aberration, led to many proposed designs and several attempts to build reflecting telescopes.[6] In 1668, Isaac Newton built the first practical reflecting telescope that bears his name, the Newtonian reflector.

    A little unrelated, but possibly interesting is the Hockney-Falco thesis, with other considerations about optics historically.

    http://en.wikipedia.org/wiki/Hockney–Falco_thesis

    More relatedly, John Dee and Thomas Digges referred to perspective glasses.

    'In 1554 a group of Oxonians invited John Dee of St. John's College, Cambridge, to come and lecture in Oxford. He refused, but his pupil Thomas Digges of Queens' College, Cambridge, came instead. He was the first English author to describe the theodolite and he edited the works of his father, Leonard Digges (University College, Oxford), who was the first maker of efficient telescopes.'

    Nice. I'd thought there was something more interesting than what I had posted, but couldn't think of it.

    Yes I'd always learned is twas the Dutch around 1600 - but it's difficult to play around with lenses (like alhazen) and not discover the telescope!

    Wow! I love telescopes. Wolram thanks for starting this topic with some great information, and mjb.phd brovo for providing one of my all time favorite links. Fuzzyfelt, enjoyed reading what you provided.

    I've been reviewing a great website this past week, thinking about buying an antique telescope. (Love to collect antiques.:smile:) Take a peak at a few of them and browse by scrolling down on the right of the website "The Developmental History of the Telescope" from the On-Line Museum and Encyclopedia of Vision Aids.
