An equitorium (plural, equitoria) was an astronomical calculating instrument. It can be used for finding the positions of the Moon, Sun, and planets without calculation, using a geometrical model to represent the celestial body's mean and anomalistic position.
It was invented by Arzachel in al-Andalus in the early 11th century.[1] Richard of Wallingford (1292–1336) is known to have built an equitorium named Albion that was utilized to calculate lunar, solar and planetary longitudes. Albion also predicted eclipses.
