This document discusses symbolism in F. Scott Fitzgerald's novel The Great Gatsby. It analyzes three main symbols: the green light, which represents Gatsby's hopes and dreams that eventually lead to disillusionment; the Valley of Ashes, which depicts the dark side of the American Dream; and Dr. T.J. Eckleburg's eyes, seen as a billboard that represents God judging humanity and those who have lost their morality. Fitzgerald uses these symbols to comment on the American culture and ideals of the time period.
