1.) The height of the North Pole above the horizon is determined on the meridian by the centre of the circuit of the outer circumpolar star, number 8.
2.) The position of the northern celestial pole is also indicated by the solar arc, depicted in the 3. production phase of the Sky Disc, because the connecting line between its ends intersects with the meridian right in the previously ascertained middle of the circumpolar stars!
3.) The horizon arcs, added in phase 2, represent the course of the sun between winter and summer solstice and as well the moon turns. However, as one can only see the latter from Earth, the golden circular disk now symbolizes the Earth.
We mark the position of the North Pole already known to us and from there we draw a connecting line to the centre of the circular disk. From the North Pole we move 51° to the right and from there we draw the horizon line once again through the centre of the disk. From the other side of the celestial pole we establish the zenith line 39° away, which coincides exactly with
