John Keats was a 19th century English Romantic poet known for his nature poetry. He found endless inspiration in nature, describing natural scenes and objects with precision. Keats believed the beauty imagined was superior to that perceived. Two of his famous nature poems are "Ode to a Nightingale" and "To Autumn", the latter celebrating the richness of the autumn season while also acknowledging its transience. Nature played a major role in Keats' work as both a source of joy and poetic inspiration.
