Some poets have been known to compose their own epitaphs prior to their death.
"Here lies one of the most intelligent animals who ever appeared on the face of the earth."
J. R. R. Tolkien is buried next to his wife, and on their tombstone the names "Beren" and "Luthien" are engraved, a fact that sheds light on the love story of Beren and Luthien which is recorded in several versions in his works.
