Changing the Angle of Vision: Astrolabe Dials on Astronomical Clocks
Abstract From the middle of the fourteenth century until the Early Modern period, several monumental astronomical clocks were erected in Europe, and on many of them astrolabe dials were placed. On a group of earlier clocks, “southern astrolabes” (i.e. with stereographic projection from the North Pol...
