After much research, I am asking for help with this matter. I can find no reverse translation for the "Book of Two Ways." Is it like the "Book of the Dead," a modern convenience name for this set of texts, when its original name wasn't discovered until more recently (rw nw prt m hrw 'Utterances of Coming Forth in the Day’) ? Or is there no known name for it? I have read that it is also called the “Guide to the Ways of Rostau”. If anyone knows the original Egyptian name for either of these two naming conceits and could share them, I would be grateful.
