The carving dates back to the 1st century AD and was originally part of the Temple of Hercules Victor.
The mask was moved to the portico of the Church of Santa Maria in Cosmedin in 1632.
Historically, the mask may have functioned as an oracle, with people hidden behind it to speak for the stone face.
The name 'Bocca della Verità' was only officially documented in written records starting in the 15th century.
Despite its fearsome reputation, the sculpture's original purpose was purely utilitarian, likely serving as a drain for the Forum Boarium.
During the Middle Ages, the sculpture served as a trial by ordeal where individuals accused of infidelity or perjury were brought to prove their innocence.
The Mouth of Truth, or Bocca della Verità, is a massive circular marble mask featuring a bearded face, housed in the portico of the Church of Santa Maria in Cosmedin in Rome. It is carved from pavonazzetto marble and measures approximately 1.75 meters in diameter. Medieval legend claims that the mouth will bite off the hand of any liar who inserts it into the opening. The carving is widely believed to be an ancient Roman manhole cover or a drain cover dedicated to a river god. The artifact gained international fame through its appearance in the 1953 film Roman Holiday. It remains a popular site for visitors to test their honesty by posing for photos with their hands inside the stone mouth.

Queue early to minimize the wait, as the line for the photo opportunity often extends outside the church portico.
Have your camera ready and framed before your turn at the mask, as staff generally keep the line moving quickly.
Combine your visit with a brief tour of the interior of the Church of Santa Maria in Cosmedin to see its notable 12th-century floor mosaics.
Do not wait in the long queue if you only want to view the carving; you can see it clearly from the side of the portico without joining the photo line.
Modest dress is required as the mask is located within a functioning church; ensure shoulders and knees are covered.
