Tom Lovell's painting The Angel Moroni Appears to Joseph Smith in his Room is an important one for the Church of the Latter Day Saints. It was during that this visitation that Smith's mission was revealed, along with the secret that there was a book written on gold plates buried on a hillside. These contained a gospel and a secret history of the ancient inhabitants of the American continent, and would become what is now known as The Book of Mormon. Moroni also made it clear that Smith should not show the original gold plates to anyone, ever, and that they would just have to take his word for it. And they did.
