KBo 20.64: A Hittite Invocation Ritual mentioning the Thunder

The short Hittite fragment 1086/c=KBo 20.64, currently listed among the texts related to the festival of the thunder under the number 631 of the Catalogue des Textes Hittites, presents some features that clearly distinguish it from the other documents collected under the same catalogue entry. It represents in my opinion what is left of an invocation ritual directed to a deity, probably to be identified with a hyposthasis of the storm-god, as the presence of the word tetḫeššar, “thunder” in the colophon seems to suggest. The text must therefore be collocated elsewhere, and I propose, in consideration of its content and structure, to place it either among the fragments of mugawar for the Storm-god under CTH 332 or, more generally, under CTH 459 (Fragments of mugawar). The paper presents for the first time transcription, translation and commentary of the fragment. Interesting elements emerge from the comparison with KBo 30.119, another fragmentary tablet, erroneously classified among the fragments of festivals under CTH 670, where a similar invocation ritual seems to be described.
