Raffaello Sanzio is the artist who is better known simply as Raphael. He lived from 1483 to 1520 in Italy.
He was buried in the Pantheon because he requested that he should be buried there. Of course, his request was only granted because of his fame and political connections. He was a very famous artist even in his own time and was connected to various influential people in Rome (including cardinals and other such important church figures.
His death is compared to Christ's only in that both of them died on Good Friday.
Raffaello Sanzio, primarily known as Raphael, was a magnificent Italian painter. Raphael became devoted to the Vatican and most of his projects were done for the Vatican. He did not live a long life and died when he turned 37, on his birthday. He was born on a Good Friday and died on Good Friday.
Raphael was going to be invested as a cardinal in the Catholic Church, but he died before he could be invested. Because of his dedication to the Vatican and his commitment to the Catholic Church, he was given an extravagant public funeral and a burial in the Pantheon which was reserved from the most highly regarded.
I could not find any information about his death being Christ like.
