This new study offers a comprehensive examination of a unique manuscript, a Late Period hieratic papyrus in the Brooklyn Museum. This document comprises a compilation of seventeen individual prophylactic texts whose anatomical focus is the ear. Many of the texts specifically state that they are intended for the protection of the ears of a king named Psamtik, a historical figure who ruled Egypt in the seventh century BCE. The fact that this papyrus was created to serve a sole purpose and function, the protection of the ear, distinguishes it noticeably from earlier Egyptian medical and magical texts that are largely encyclopedic and were intended to serve a broad range of purposes. The present study contains an introduction and full translation with extensive philological and textual commentary, as the texts of this papyrus are rich in mythological allusions. The commentaries are largely based on comparison with contemporary and older Egyptian texts that, although not direct parallels as there are none, serve nonetheless as a rich resource for comparative analysis that has led to a more informed reading of this important document. Includes 34 colour plates and 5 b/w tables.
