"This date  probably refers to the initial event depicted in the upper register, the presentation of the royal heir to the assembled court, fourteen lords dressed in long white mantles."
NOTE: The infant heir appears at the right in this photo, held by an attendent standing on a slightly raised dias. The paint representing his eye had been scratched off in later times, a practice which served to nullify any power associated with a carved or painted work of art. The assembled lords pictured here seem to be conversing among themselves and paying little attention to the infant heir.
