What is "sag-gig-ga-mes"

The incantation series inscribed in cuneiform Sumerograms as ÉN SAG.GIG.GA.MEŠ, Akkadian: muruṣ qaqqadi, “headache” (literally “sick-head”), is an ancient Mesopotamian nine-tablet collection of magical prescriptions against the demon that caused grave disease characterized by a headache. Some of its incantations seem to have become incorporated into the later Assyrian work muššu’u, “rubbing”. It is listed on the ninth line of the KAR44, the work known as the Exorcists Manual, a compendium of the works of the āšipūtu, craft of exorcism, prefixed by the gloss sa.kik.ke, a phonetic rendition of the series’ opening incipit, én sag-gig é-kur-ta nam-ta-è.
