Autobiography of Red is the story of a boy named Geryon who, at least in a metaphorical sense, is the Greek monster Geryon. It is unclear how much of the mythological Geryon's connection to the story's Geryon is literal, and how much is metaphorical. Sexually abused by his older brother, his affectionate mother too weak-willed to protect him, the monstrous young boy finds solace in photography and in a romance with a young man named Herakles. Herakles leaves his young lover at the peak of Geryon's infatuation; when Geryon comes across Herakles several years later on a trip to Argentina, Herakles' new Peruvian lover Ancash forms the third point of a love triangle. The novel ends, ambiguously, with Geryon, Ancash, and Herakles stopping outside a bakery near a volcano.
The book also contains Carson's very loose translation of the Geryoneis fragments, using many anachronisms and taking many liberties, and some discussion of both Stesichorus and the Geryon myth, including a fictional interview with "Stesichoros", a veiled reference to Gertrude Stein.
