The earliest depictions of male circumcision come from ancient Egypt's sixth dynasty (2345 - 2181 BC). This illustration is based on a relief from the tomb of Ankhmahor, a vizier with an interest in medical procedures:
Ankhmahor's tomb is mostly known because of several scenes of people undergoing some medical treatment. This has earned this tomb the name "the tomb of the physician", even though Ankhmahor was not a physician at all.
Nurse Myra features this cringe-worthy art in an interesting post on the history of suturing at the Gimcrack Hospital. Hint: Ant-heads, ant-heads, roly-poly ant-heads . . .
