One of the oldest graphical proofs of sadomasochistic activities is found in the Etruscan Tomb of the Whipping near Tarquinia, which dates to the 5th century BC. Inside the tomb, there is a fresco which portrays two men who flagellate a woman with a cane and a hand during an erotic situation. Another reference related to flagellation is to be found in the sixth book of the "Satires" of the ancient Roman Poet Juvenal (1st–2nd century A.D.), further reference can be found in Petronius's "Satyricon" where a delinquent is whipped for sexual arousal. Anecdotal narratives related to humans who have had themselves voluntary bound, flagellated or whipped as a substitute for sex or as part of foreplay reach back to the 3rd and 4th century BC.
