FIRST EDITION of this luxuriously printed and illustrated work, which describes and illustrates the astronomical instruments in the private observatory of Marinoni, mathematician and astronomer to the Imperial Court of Austria and geodetic surveyor. Like the private observatories of Tycho Brahe and Hevelius in the two preceding centuries, Marinoni's observatory was one of the most beautiful and best equipped in Europe in his time. He built his own instruments and those illustrated here include quadrants, telescopes, micrometers, an improved Graham pendulum, and a camera obscura. Marinoni left all the instruments to the Empress Maria Theresa, to whom he dedicated this work.
