If you are looking for a gift with a story, then look no further than this Hartmann astrolabe from Hemisferium. Georg Hartmann was a well-known instrument maker in Nuremberg in the 16th century and made, among other things, astrolabes and sundials. This replica is made after his example, in a size of 15 cm. An astrolabe is a flat model of the sky that allows you to determine the position of the sun and stars and the time.<\/p>\n\n\n\n
It is primarily a decorative and educational object for a desk or bookcase. Those who want to juxtapose astrolabia from different traditions also look at the Arabic astrolabium<\/a>.<\/p>\n\n\n\n If you really want to get started, take the time to learn about it; using an astrolabe takes practice. A book in Dutch like Rob Walrecht's own star gazing<\/a> helps to get to know the starry sky from outside.
