Michelangelo's Pietà in St. Peter's Basilica in the Vatican

Michelangelo's Pietà, a depiction of the body of Jesus on the lap of his mother Mary after the Crucifixion, was carved in 1499, when the sculptor was 24 years old.

In November of 1497, the French ambassador in the Holy See commissioned one of his most famous works, the Pietà and the contract was agreed upon in August of the following year. The contemporary opinion about this work — "a revelation of all the potentialities and force of the art of sculpture" — was summarized by Vasari: "It is certainly a miracle that a formless block of stone could ever have been reduced to a perfection that nature is scarcely able to create in the flesh."
