Archeantus was a Nephite briefly mentioned in the Book of Mormon. As recorded in the Book of Moroni, Moroni copied a second letter that his father Mormon had written to him prior to being killed by the Lamanites. Mormon told his son of several "choice men" who were killed by the Lamanites. Archeantus was one of these.[1] This article related to a Book of Mormon Character is a stub.
