The carved 'Circumcision Scene' in the temple of Khonsupakherod, northern wall, within the Temple Precinct of Mut (18th Dynasty).
"They drink only from copper vessels, which they polish and clean every day with a great deal of care... They wear clothes of linen that are always freshly washed and that they take pains never to stain. They have adopted circumcision in their search for cleanliness, and appear to think more highly of a perfect physical purity than any other adornment." (Herodotus)
