    Description
    Johannes Hevelius' 150 foot refracting telescope.

    The lenses are arranged inside a wooden trough, and the trough is suspended from a 90 foot pole. Work men and horses can be seen at the base of the telescope, operating it via a system of ropes and pulleys, and Hevelius stands at the eyepiece gesturing skyward in the bottom right corner [as viewed]. A crowd gathers to observe the spectacle, and a town, likely Danzig, is visible in the background.

    Johannes Hevelius (1611-1687) Polish astronomer was elected a Fellow of the Royal Society in 1664. He devoted much of his life to constructing astronomical instruments, and developed a well-equipped observatory in Danzig, Poland.
    Object history
    The Royal Society possess a copy of Volume 1 of Machinae coelestis pars prior… only. Volume 2 is rare, as many copies were burned in the fire of Hevelius' home and observatory in 1679.
