The translation was commenced by the prophet himself, who was enabled to read the “reformed Egyptian” by the aid of the “peepstone.” This was done by putting the stone in a hat or box, and then by applying his face, the prophet was enabled to read one word at a time, which he pronounced aloud to an amanuensis.
