Book of Bee mentions "Book of Memorials"


Hi Everyone,

In Book of Bee, last chapter:

The author mentiones “Book of Memorials”. Does anyone knows what it is or who is the author ? I tried to find some info, but without luck.
Ilaria Rameli mentions this chapter in her work about Apocastastis, but I don’t have her full book, in portions that I am able to access on Google Books, it is not clear on what is this book.

Thanks for any info.
