This paper explores the deep interconnection between 18th-century English landscape gardening and English poetry of the 18th and early 19th centuries, both of which were shaped by a prevailing aesthetic philosophy emphasizing emotion and imagination. The landscape gardener is presented as a poetic figure, using natural forms and architectural elements much like a poet uses language to evoke emotion and symbolize deeper meaning. The paper draws parallels between these art forms to illustrate how both reflected the spirit and philosophical underpinnings of their time. The study begins with a historical overview of the foreign influences on English gardening styles, tracing the transition from Italian Renaissance, French, and Dutch models to the uniquely English landscape garden. It then delves into key influences—political context, topography, climate, literature, travel, painting, and aesthetics—that collectively fostered a new appreciation for nature and informed this stylistic transformation.
