did michelangelo carve entire pieta sculpture
Following completion, the Pietà’s first home was the Chapel of Santa Petronilla, a Roman mausoleum near the south transept of St. Peter’s, which the Cardinal chose as his funerary chapel. The chapel was later demolished by Bramante during his rebuilding of the basilica. According to Giorgio Vasari, shortly after the installation of his Pietà, Michelangelo overheard someone remark (or asked visitors about the sculptor) that it was the work of another sculptor, Cristoforo Solari, whereupon Michelangelo signed the sculpture.  Michelangelo carved MICHAELA[N]GELUS BONAROTUS FLORENTIN[US] FACIEBA[T] (Michelangelo Buonarroti, Florentine, made this) on the sash running across Mary’s chest. The signature echoes one used by the ancient Greek artists, Apelles and Polykleitos. It was the only work he ever signed. Vasari also reports the anecdote that Michelangelo later regretted his outburst of pride and swore never to sign another work of his hands.  
When Michelangelo set out to create his Pietà, he wanted to create a work he described as “the heart’s image”. 
The marble of the sculpture is so shiny it was said that Michelangelo spent as much time polishing his masterpiece as he did sculpting it. This desire to give the statue such luminosity was probably to contrast the darkness of the Chapel of Saint Petronilla.
Michelangelo’s Pietà is one of the most beautiful sculptures in the history of art and one of the most representative works of the Renaissance ideal.
The scene of the Pieta shows the Virgin Mary holding the dead body of Christ after his crucifixion, death, and removal from the cross, but before he was placed in the tomb. This is one of the key events from the life of the Virgin, known as the Seven Sorrows of Mary, which were the subject of Catholic devotional prayers. The subject matter was one which would have probably been known by many people, but in the late fifteenth century it was depicted in artworks more commonly in France and Germany than in Italy.
Here is perfect sweetness in the expression of the head, harmony in the joints and attachments of the arms, legs, and trunk, and the pulses and veins so wrought, that in truth Wonder herself must marvel that the hand of a craftsman should have been able to execute so divinely and so perfectly, in so short a time, a work so admirable; and it is certainly a miracle that a stone without any shape at the beginning should ever have been reduced to such perfection as Nature is scarcely able to create in the flesh. Such were Michelagnolo’s love and zeal together in this work, that he left his name a thing that he never did again in any other work written across a girdle that encircles the bosom of Our Lady. And the reason was that one day Michelagnolo, entering the place where it was set up, found there a great number of strangers from Lombardy, who were praising it highly, and one of them asked one of the others who had done it, and he answered, “Our Gobbo from Milan.” Michelagnolo stood silent, but thought it something strange that his labors should be attributed to another; and one night he shut himself in there, and, having brought a little light and his chisels, carved his name upon it.
Vasari’s Lives of the Artists
French cardinal Jean de Billheres, who served the church in Rome, wanted to be remembered long after he’d died. To achieve this goal, he hired Michelangelo to make a memorial for his tomb that would capture a scene that was popular in Northern European art at the time: the tragic moment of the Virgin Mary taking Jesus down from the cross.
In the wake of his work with Hitchcock, Walt Disney approached Dalí in 1945 about joining Disney Studio to work on an animated film called Destino, featuring a score by Mexican composer Armando Dominguez. Dalí had drawn up 22 oil paintings and stacks of drawings, and he and legendary Disney designer John Hench created storyboards for the film. But only eight months after they started, the project was shelved for financial reasons, with only 15 seconds of demo reel completed. (Disney and Dalí remained friends despite the hiccup.) In 1999, Roy E. Disney, Walt’s nephew, decided to restart the production. Animators at Walt Disney Studios Paris painstakingly translated Dalí’s original storyboards to create a film faithful to his vision. The 6-minute short was released in 2003.
The Pieta, which depicts the Virgin Mary holding the body of her son Jesus Christ after his death, has been created in many different forms by various painters and sculptors. Of all the great paintings and sculptures on the Pieta, however, the one by Michelangelo stands out from all the rest.
When it was unveiled a proud Michelangelo stood by and watched as people admired the beautiful Pieta. However, what was pride quickly turned into anger as he overheard a group of people attributing the work to other artists of his time. That anger caused Michelangelo to add one last thing to his sculpture. Going down the sash on the Virgin Mary, Michelangelo carved his name. He later regretted that his emotions got the best of him and vowed to never sign another one of his works again.
