F. B. Jevons 
Introduction to the History of Religion (Routledge Revivals) [PDF ebook] 

First published in 1902, this book investigates the history and development of early religion from an anthropological perspective. Rather than dealing with religions that grew from the teachings of their original founders, such as Christianity, Islam, and Buddhism, Jevons considers those religions that were practised as a matter of custom and tradition. The title considers such subjects as the supernatural, life and death, animal sacrifice, and the worship of nature. It provides an introduction to the history of religion for students of religion, anthropology and folklore.
