Greek religion  

"Greek religion, as set forth in popular handbooks and even in more ambitious treatises, is an affair mainly of mythology, and moreover of mythology as seen through the medium of literature. In England, so far as I am aware, no serious attempt has been made to examine Greek ritual. Yet the facts of ritual are more easy definitely to ascertain, more permanent, and at least equally significant. What a people does in relation to its gods must always be one clue, and perhaps the safest, to what it thinks. The first preliminary to any scientific understanding of Greek religion is a minute examination of its ritual."--Prolegomena to the Study of Greek Religion (1903) by Jane Ellen Harrison
