Keats was fascinated by Greek literature, sculpture, and culture. He felt the materialism of the 19th century lacked meaning, and preferred the pagan worldviews of ancient Greece. This Hellenic influence is reflected in Keats' poetry, including his ode to Autumn. The ode personifies Autumn and uses vivid imagery and descriptions of the natural world found in Greek art and literature. It also references Greek traditions like invoking the muses and sees nature's beauty as something immortal, reflecting Keats' fascination with Greek ideals of physical perfection and appreciation for the natural world.
