The astrolabe is a historical astronomical instrument and analog computer used by classical astronomers and astrologers. Its many uses included locating, and predicting the positions of, the Sun, Moon, planets and stars; determining local time given local longitude, and vice-versa; surveying and triangulation. Astrologers of the Islamic world and European nations used astrolabes to construct horoscopes. ...more on Wikipedia about "Astrolabe"

The Magdeburg hemispheres were one of Otto von Guericke's most interesting experiments, designed to demonstrate the air pump he had invented. They were two hollow copper hemispheres a little over a foot in diameter which fitted together so well that they could hold a vacuum. The air was pumped out from between them, and they were then held firmly together by the air pressure of the surrounding atmosphere. ...more on Wikipedia about "Magdeburg hemispheres"

An orrery is a mechanical device that illustrates the relative positions and motions of the planets and moons in the solar system in heliocentric model. They are typically driven by a large clockwork mechanism with a globe representing the Sun at the centre, and with a planet at the end of each of the arms. ...more on Wikipedia about "Orrery"
