Astrolabe Catalogue

Tympan

6a

This side of the plate bears an astrological gazetteer. Where normally the gazetteer contains the longitude and latitude of a city, here both the ruling sign and planet is given for each city. In this transcription of the gazetteer, the columns for longitude and latitude reflect this astrological information. This tympan itself is made from a different brass, and some of the information is engraved in a different hand.
