This chapter examines the influence of William Bartram´s Travels through North and South Carolina, Georgia, East and West Florida on the writing of Wordsworth and Coleridge in the 1790s and highlights the uniqueness of Bartram´s eco-centric approach to sublimity in early American thinking about the natural world. A practiced botanist and natural illustrator, Bartram delights in cataloguing plant and animal lives, but the Travels also offers a significant intervention into trans-Atlantic discourses of sublimity. Bartram´s sublime overwhelms the perceiver with plentitude rather than terror, and he narrates experiences of sublimity from amidst the rich life he delights to describe rather than at a distance. He emphasizes continuity between human and more-than-human lives. Bartram also resists the nationalistic orientation of his American contemporaries, attending to native and local epistemologies. The chapter concludes with comparisons between passages of the Travels, Coleridge’s “Kubla Khan,” and Wordsworth’s “Ruth.”
