A pietà (Italian meaning "piety", "compassion") is a subject in Christian art depicting the Virgin Mary cradling the dead body of Jesus, most often found in sculpture.
A famous example by Michelangelo was carved from a block of marble and is located in St. Peter's Basilica in the Vatican City. The body of Christ is different from most earlier pietà statues, which were usually smaller and in wood. The Virgin is also unusually youthful, and in repose, rather than the older, sorrowing Mary of most pietàs. She is shown as youthful for two reasons; God is the source of all beauty and she is one of the closest to God, also the exterior is thought as the revelation of the interior (the virgin is morally beautiful).
