Joseph Smith/Translator
Criticism
Critics claim that Joseph Smith claimed to translate other texts or items, which can be checked against modern academic translations. They claim that this "cross-checking" proves that Joseph could not have translated the Book of Mormon or other ancient texts.
Book of Abraham
Greek psalter
Critics claim that an ancient text of Greek psalms (a "psalter") was misidentified by Joseph Smith as a containing Reformed Egyptian hieroglyphics.
