What is "mis-pi"

Mîs-pî, inscribed KA-LUḪ.Ù.DA and meaning “washing of the mouth,” is an ancient Mesopotamian ritual and incantation series for the cultic induction or vivification of a newly manufactured divine idol. It involved around eleven stages: in the city, countryside and temple, the workshop, a procession to the river, then beside the river bank, a procession to the orchard, in reed huts and tents in the circle of the orchard, to the gate of the temple, the niche of the sanctuary and finally, at the quay of the Apsû, accompanied by invocations to the nine great gods, the nine patron gods of craftsmen, and assorted astrological bodies.
