The lascivious mores of the Egyptians under the guise of veneration of the priapic bull Apis, and their obscene dances, rituals, and similar performances are described and commented on in great detail by Herodotus in his History of the Persian Wars.
The genitalia and all references to the phallic image were in very ancient times held in such sacred esteem and reverence that in Biblical literature the inviolable sanctity of an oath was ratified by touching the area of the genitalia, or the thigh, to use the Biblical euphemism. The Hebrews especially held the generative organs in the greatest respect, socially, ethnically, and religiously: and nudity as a consequence was a matter of shameful stigma and opprobrium.
Among the Moslems too the most binding oath was taken with respect to the sanctity of the genitalia.
In Egypt, in the temple of Isis, sacred prostitution was a regular religious practice. Reference to this circumstance is made by the Roman satirist, Juvenal, who calls Isis a procuress and her shrine a rendez-vous for adulterous and libidinous practices.
Among symbolic emblems that represented, in combination, the male and female principles of generation and fecundity, were the Egyptian crux ansata and the seal of Solomon.
