The Colossus of Maroussi is an impressionist travelogue by Henry Miller, written in 1939 and first published in 1941 by Colt Press of San Francisco. As an impoverished writer in need of rejuvenation, Miller travelled to Greece at the invitation of his friend, the writer Lawrence Durrell. The text is inspired by the events that occurred. The text is ostensibly a portrait of the Greek writer George Katsimbalis, although some critics have opined that is more of a self-portrait of Miller himself. Miller considered it to be his greatest work.
