At the center of the novel is a group of four characters. These are two young American artists, Hilda and Kenyon, who were brought to Rome by a thirst to comprehend the secrets of art, and their friends the artist Miriam and the young Donatello, who are introduced into this circle not by a passion for art, but by love for Miriam. Everyone is struck by the similarity of the count with the famous statue of Praxiteles, depicting a faun. Most importantly, this similarity is not limited to external similarity: traits dominate in the depiction of his image, beyond which the innocence of a creature unaware of the existence of evil is revealed.
