The Bocca della Verita (Mouth of Truth) can be admired in the portico of the Chiesa di Santa Maria in Cosmedin in Rome, Italy. It is a statue, made of white Pavonazzetto-marble, and shows the round face of a man, with an open mouth.
Mouth of Truth Rome
It is believed in the past to have been part of an ancient Roman fountain or manhole. It was not until the 17th century that it was placed in the Church of Santa Maria in Cosmedin. Originally it probably was a picture of some pagan god.
According to legend, when a person puts her hand into the Bocca della Verita, and has been telling lies, the hand will be bitten off, an idea that is used in the famous movie “Roman Holiday“.
