From Ritual to Romance was written in 1920 by Jessie L. Weston. The book was made famous by being mentioned by T. S. Eliot in the notes to his poem, The Waste Land. He says, "Not only the title, but the plan and a good deal of the incidental symbolism of the poem were suggested by Miss Jessie L. Weston's book". The book centres on an examination of the roots of the King Arthur legends and seeks to make connections between the early pagan elements and the later Christian influences. In particular, the book looks at the Holy Grail tradition and its influence.
