Michelangelo

The last Pieta he made for the cathedral in Florence was intended in his last will for his tomb.

An excerpt from the article 32 facts about Michelangelo
Michelangelo loved to create significant, monumental things. He was not satisfied with commissions of small forms in small churches or private galleries. He needed big challenges to be fully realized. Michelangelo often refused others' help and took him a great deal of effort to complete an order. He became a self-tormenting loner who shied away from people. He left his studio less and less often, giving the impression of being constantly insatiable, chasing new orders and projects.
