Who received a prosthetic ivory shoulder after being cut to pieces and served at a feast?

The individual who received a prosthetic ivory shoulder after being cut to pieces and served at a feast is Pelops. In Greek mythology, Pelops was the son of Tantalus. Tantalus committed a heinous act by killing his son Pelops and serving him to the gods at a banquet to test their omniscience. The gods, however, noticed the trickery and revived Pelops, putting his remains back together but replacing the part that had been removed with an ivory shoulder, which became a symbol of his resurrection and the divine favor bestowed upon him.

This story illustrates themes of sacrifice, resurrection, and the consequences of hubris and transgression that are prevalent in Greek myths. Pelops later became a legendary figure in other myths, including the stories related to the Chariot Race and the founding of the Olympic Games.
