In Europe the Astrolabe became an essential instrument for astronomers, astrologers and surveyors until the end of the 17th century when it was replaced by more accurate instruments. In the Arab world its use lasted until the 19th century.
This planispheric astrolabe is based on an original piece by the German maker G. Hartmann in the British Museum, London.
Georg Hartmann or Georso of the Gius Hartmann (Germany, 1489-1664) was a true Renaissance man. He settled in Nuremberg from 1518 and developed his enormous oeuvre there. Shortly before 1523 he had already established a powerful workshop specializing in the manufacture of scientific instruments. Many of his instruments have come down to us: sundials, astrolabes, quadrants and astronomical and astrological compendia.
He was probably the most prolific of the "instrument makers" in the first half of the 16th century. His instruments reflect his "great workshop" origin, an early version of a planned production system.
This astrolabe is calculated for 50º.
