The Church of the Latter Day Saints believes that the Book of Mormons was inscribed on golden plates in some form of the Egyptian language, described as Reformed Egyptian by Joseph Smith. The golden plates were buried in the hills of Manchester, New York by the last of their prophets, Moroni. Later, Moroni, the prophet returned as an angel and informed the prophet Joseph Smith where the golden plates were located. On September 22, 1827, Joseph Smith started translating the Book of Mormons and three years later the Book of Mormons went on sale.
