As a part of the Creation Series of the early 20th century, Petries' work here on Ancient Egypt is a great compilation of basic content; many dozens of gods, books, and historical epochs within the antiquated period are discussed in regards to Egyptian religion- one which briefly dabbled in monotheism with Akhenaten centuries before Christendom, and which was able to evolve for many thousands of years more than almost any other religious form.While some of the material here is academically outdated it also represents a unique period in occult study; the renaissance of the late 19th and early 20th centuries in spiritual study and rapid outgrowth of religious history in its era.
