Published in five volumes between 1896 and 1909, this book separates Greek religious practice from its corresponding mythology. Focusing on the most popular gods, Farnell describes their cults, monuments and ideal types. Volume 3 focuses on the cults of Ge, Demeter, Hades, and Rhea.

Facilitating a comparative approach to the cults of Greek gods, Farnell's five-volume work (1896 1909) is still regularly consulted.
