What is "petiese"

Petiese (alt. Peteese, Pediese) was the name of a number of high ancient Egyptian officials who served the pharaohs during the seventh and sixth centuries BCE. Their family history is known from a petition (pRylands 9) which the priest Petiese (referred to below as Petiese III) wrote during the reign of Darius I of Persia, although some have claimed that, rather than a real petition, this is a work of literature or at best a draft for a petition.
