Lake Moeris
The book, though a product of the Roman Period of Egyptian history, is rooted in the established canon of Egyptian religious thought. Influences from and references to religious texts that were common in pharaonic Egypt are seen throughout the entirety of the "Book of the Faiyum," standing as a testament to the longevity of Egyptian religion. Among these references to earlier doctrine is an outline of the basic journey of the sun god, Re, which is detailed in older texts, like the New Kingdom Amduat funerary texts. Re was thought to grow old in the course of each day and then rejuvenate during the night so he would be reborn again at sunrise. This theme is explored extensively in the "Book of the Faiyum", as Sobek is portrayed as a manifestation of Re. However, deviating from New Kingdom traditions, Sobek-Re’s journey through the day concludes not with his descent into the Duat (afterworld), but rather, Lake Moeris, the lake that is central to the Faiyum oasis. It is through the lake, not the underworld, that Sobek-Re makes his nightly journey.
