What is the theme in The Passion by Jeanette Winterson?

Despite the objectivity often maintained, perhaps even expected, by historical fiction, The Passion is often penetrated by events both fantastical and miraculous. This begins with subtlety, as a story told by Patrick to Henri. Patrick tells of his telescopic eye and the goblin magic which shrank his shoes. The dynamic continues with Villanelle, who narrates the mystical origin of Venetian boatmen and the nature of her webbed feet.
