The Horologium is the Monumental Clock created in several European churches in the Middle Ages. It shows the position of planets, moon and sun and dawn and dusk.
For the Northern Hemisphere it is a stereographic projection from the celestial North pole. Therefore it can only project lower altitudes.The Horologium is intuitively more like a clock than the Astrolabe. The Astrolabe is for the Northen Hemisphere projected from the celestial South pole.
