Encyclopaedia of Religion and Ethics
"The Encyclopaedia of Religion and Ethics is a 12-volume work (plus an index volume) edited by James Hastings, written between 1908 and 1927 and composed of entries by many contributors. It covers not only religious matters but thousands of ancillary topics as well, including folklore, myth, ritual, anthropology, psychology, etc. It was originally published by T&T Clark in Edinburgh, and Charles Scribner's Sons in the United States."--Wikipedia.
