Literature from the United Kingdom and the United States represents the cultural expression of those peoples' lived experiences. Reading British and American literature may also aid in our understanding of the values, worldview, and ideological underpinnings of western civilization. Therefore, this thesis examines the mythological and religious themes in British and American literature using literary works from both countries. Greek Myth is the source and soil of ancient Greek literature, and ancient Greek and Roman literature is a rich treasure for later generations to understand myths, both of which provide creative materials for later British and American writers. It can be said that myths and religious ideas gave birth to great literary works and some immortal poets. Among them, "Wuthering Heights" is the main representative work of 19th century literature and occupies an important position in the history of British and American literature. Based on this, this paper discusses the religious and cultural characteristics of British and American literature in "Wuthering Heights", mainly from the perspective of environment description and plot shaping. I hope this research can play a role in attracting jade.
