This book is at the top of many lists for those wishing to study ancinet Egyptian religion in-depth. Upon reading it, I can see why! This book explores what exactly the ancient Egyptians thought god(s) were, how the gods reacted to humans, and how humans reacted to the gods. Given the unique and often confusing nature of the concept "ntr" or god, this book is very useful indeed.
It is extermely detailed, (though admittedly dry,) and leaves the reader with a good idea of what the Egyptian Gods were like and how they developed throughout the millenia. The beginning also nicely addresses the erroneous notion that the Egyptians were really monotheists from the start, and that only the ignorant common people held polythistic beliefs; a Victorian bias that taints the studies of many ancient cultures. Horning clearly has a great deal of respect for the ancient Egyptian religion, and as a Kemetic pagan, I really appreciate that this book exists in English.
