It was not until a new gallery with a cafe was built in the church in the 1990s that the artwork was discovered.
The reclining nude man, nicknamed Seamus O'Toole, is believed to have been carved into the rafters in the 15th century.
The images made it onto Reddit where thousands of people commented, many pointing out the artwork is proof trolling is not a modern thing.
Parishioners at the church in Hereford were shocked by the discovery. Photo / Facebook/All Saints Church"He probably sat in the church, looking up at, knowing no one else knew it was there, tittering to himself," one person wrote.
"Words can't describe how much I love this," another one said.
"Never in a million years did the person who made this think thousands of people around the world would see it," someone else pointed out.
