On DAY 15 of the nuntarriyašḫa- festival, the king travels from Katapa to Taḫurpa, where a great assembly is convened. A comparable journey and an identical ceremony in Taḫurpa are already attested on DAY 4, although on that earlier occasion the king also made an additional visit to Ḫišurla. Since the outline tablets provide no further details for DAY 15, the close similarity between the two days makes it exceedingly difficult to identify any day-tablets that can be securely attributed to the events of this day. It therefore remains possible that some manuscripts currently assigned to DAY 04 in fact describe DAY 15. Conversely, one may question whether any day-tablets for DAY 15 were produced at all, since, especially with respect to the great assembly, the ritual procedures could readily have been reconstructed by reference to the already existing day-tablets of DAY 4.
