Andy Plant. Orrery built for the 1997 Stockton Theatre Festival. A 40′ high, temporary outdoor floating sculpture, where a rotating orrery, with planets, is operated by a performer inside the main sphere.
Evidently common enough to be in schoolrooms, this one in Germany.
An orrery, ca 1900. The arm is manually rotated by worm and wheel below a circular calendar disc printed with months, date, zodiac and seasons. The candle reflects light over the wood moon onto the terrestrial globe. signed 'Erd Globus v. 15cm. durchm. von Dr. H. Fischer Wagner & Debes, Leipzig Lehrmittelanstalt' 19in / 48.5cm high
Compared to William Pearson's orrery design below of the whole solar system, this schoolroom orrery is just the sun, the earth and the moon. It must have been magical.
A drawing of a machine to illustrate the orbits of the planets. It appears to owe much to clock and watch mechanisms, cogs and wheels: the largest system illustrated by the smallest devices at the time.
