 Especially intriguing is the fact that palatial and ceremonial structures of these cultures were carefully aligned to the celestial pole and the procession of pole stars.Pankenier notes that the true celestial pole lies in a sky template which is vacant of significant stars, and that the various pole stars are those nearest to this vacant apex which is of crucial importance.He illustrates how the Shang oracular script for Di can be projected on the north pole template of the ancient sky in such a way that its extremity points correspond with the visible star, while the intersection of the linear axes at the centre will map to the vacant celestial pole.
