What is the theme in The Return of the Native by Thomas Hardy?

The role of time and the effect of its passage are major themes in the novel. As the story spans eighteen months, the landscape of the heath remains unchanged—that consistency is reflected in the people who live on the heath for generation after generation. They are creatures of tradition, following the same wedding rituals, the same harvest rituals, the same holiday traditions and the same folk remedies (such as the traditional cure for an adder's bite) that has been handed down to them. Sometimes traditional beliefs lead to hostility, like the fear of Eustacia Vye being a witch.
