The Nuremberg workshop and print-shop of Georg Hartmann had a large output and a widespread influence. Hartmann was a friend of Schöner and of Georg Joachim Rheticus, who became the disciple of Copernicus. Like other mathematical writers of the time, Hartmann was a printer and a globe- and instrument-maker. This astrolabe was owned by William Laud, Archbishop of Canterbury in the 17th century; the black appearance of its exposed surfaces is the result of atmospheric conditions, perhaps due to being kept in a gas-lit room.
