Perhaps the most notorious of Hofmann's Mormon forgeries, the Salamander letter, appeared in 1984. Supposedly written by Harris to W. W. Phelps, the letter presented a version of the recovery of the gold plates that contrasted markedly with the church-sanctioned version of events. Not only did the forgery intimate that Smith had been practicing "money digging" through magical practices, but it also replaced the angel that Smith said had appeared to him with a white salamander.[28]
After the letter had been purchased for the church and become public knowledge, LDS Church apostle Dallin H. Oaks asserted to Mormon educators that the words "white salamander" could be reconciled with Smith's Angel Moroni because, in the 1820s, the word salamander might also refer to a mythical being thought to be able to live in fire, and a "being that is able to live in fire is a good approximation of the description Joseph Smith gave of the Angel Moroni."[29]
