[3] Scholars have argued about the original function of this ivory, whether it was the tip of a scepter, or the grip on the lid of a casket containing a crown.
However, recent scholars have argued that the ivory was in fact a ceremonial comb made probably for the Emperor Leo VI.
The iconography on the back represents the Virgin Mary crowning an Emperor, probably Leo VI, and assisted by the angel Gabriel.
By this image of coronation, various experts have suggested the explicit willingness to show the divine approval of the imperial power on earth.
The arches, niches, and windows carved on the ivory suggest a striking resemblance with the interior architecture of the east end of the Hagia Sophia cathedral.
