In ancient Egypt, it was considered insufficiently compassionate to put an end to one's suffering via the process of death. Even in the afterlife, there was a threat around every turn, and the departed still had challenges to face and conquer.

In order to get to Aaru, the lovely region where Osiris, the God of Death, dwelt, they had to go through what essentially amounted to a spiritual obstacle course. At the very least, there were two ways to travel to Aaru: one was over land, and the other was over water. Both were difficult enough to warrant the employment of a handbook, which was aptly named the Book of Two Ways due to the fact that it detailed two distinct paths. There is a chance that this intricate map of the underworld of ancient Egypt was the first "book" ever to include illustrations in the annals of our planet's history. And it wasn't until very recently that researchers discovered a copy that is 4,000 years old; this gives it the distinction of being the oldest edition that has ever been unearthed. What terrifying signals does this book contain, and what does the content of this book represent for Egyptologists?
