Perhaps the oldest European star map was a parchment manuscript titled De Composicione Spere Solide.It was most likely produced in Vienna, Austria in 1440 and consisted of a two-part map depicting the constellations of the northern celestial hemisphere and the ecliptic.This may have served as a prototype for the oldest European printed star chart, a 1515 set of woodcut portraits produced by Albrecht Dürer in Nuremberg, Germany.During the European Age of Discovery, expeditions to the southern hemisphere began to result in the addition of new constellations.

They have been used for human navigation since time immemorial.These most likely came from the records of two Dutch sailors, Pieter Dirkszoon Keyser and Frederick de Houtman, who in 1595 traveled together to the Dutch East Indies.Their compilations resulted in the 1601 globe of Jodocus Hondius, who added 12 new southern constellations.A total of 1,345 stars are drawn, grouped into 257 asterisms.The date of this chart is uncertain, but is estimated as 705–10 AD.
