The original claim that the Book of Abraham had been translated from ancient egyptian papyri scrolls has been proven false when it was clearly shown that the scrolls where funeral text.
The Church allowed photographs of the papyrus to be published in the February 1968 edition of the Improvement Era magazine, along with an article explaining them. Now that over a hundred years had passed since the book’s translation, there were many educated people both in and out of the LDS faith who understood the Egyptian language.
During this time, many articles ran in the Improvement Era from 1968 through 1970 regarding the translation. However, the LDS experts completed work revealed – that not only did the papyri NOT contain the Book of Abraham – there was not even the slightest connection between their contents and Abraham.
What was on them?
They were simply ordinary Egyptian funeral texts – prayers to pagan Egyptian gods – that had been buried with the mummies.
Unsatisfied with the outcome, LDS leaders extended the opportunity to several other non-LDS Egyptologists to examine and comment on the papyri. Each one of them arrived at the same conclusion: the papyri were common funeral texts, all clearly dating 1500 years later than Abraham’s time – having no connection whatever with the biblical patriarch Abraham.
What Joseph Smith claimed to be the Book of Abraham, was actually the Book of Breathings. And, what was supposed to be the Book of Joseph of Egypt, was the Book of the Dead.
