— Dorsum = Astrolabe —
The astrolabe shown at right was constructed around the year 1500 most probably in Germany.
The engravings are for a latitude of 48° north.
This astrolabium was presented to me at the general assembly of the SAVAR (Société
d'Astronomie du Valais Romand) for building up their website in the year 2000. Visit the website of the SAVAR:
The SAVAR is a sister society of the AGO (Astronomische Gesellschaft Oberwallis), whose web presence
I managed from 1998 to 2013. Visit also the AGO:
Both societies are affiliated to the SAG (Swiss Astronomical Society)
