Framed Print of Astrolabe Diagram
An astrolabe is an ancient instrument used widely in medieval times by navigators and astronomers to determine latitude, longitude, and time of day. An astrolabe consists of a disk, called the mater, which is deep enough to hold one or more flat plates called tympans, or climates. A tympan is made for a specific latitude and is engraved with a stereographic projection of circles denoting azimuth and altitude and representing the portion of the celestial sphere above the local horizon. The rim of the mater is typically graduated into hours of time, degrees of arc, or both. Above the mater and tympan, the rete, a framework bearing a projection of the ecliptic plane and several pointers indicating the positions of the brightest stars, is free to rotate. Some astrolabes have a narrow rule or label which rotates over the rete, and may be marked with a scale of declinations. The astrolabe was replaced by the sextant in the 18th century. © New York Public Library / Science Source
