Arabic astrolabium, replica | Hemisferium

Anyone interested in the history of science will quickly come across the astronomers from the Islamic world. In the Middle Ages, the astrolabe was further developed and used there. With an Arabic astrolabe, they determined the time and the prayer times and calculated the position of the sun and stars. An astrolabe is a flat model of the sky with a rotating star map.

This version of Hemisferium is a replica based on historical examples and is intended primarily as a decorative and educational object. A gift for anyone who is interested in astronomy, history, or the science of the Islamic world. A later European variant is The universal astrolabe of Juan de Rojas.
