Abstract:Stephen Crane was an outstanding American novelist,poet,and journalist.He achieved great success in his literary works during his brief career.Crane’s most well-known work,The Red Badge of Courage,is commonly believed to be the first great novel of the American Civil War,largely because of its vivid and detailed description of the experience of warfare.This paper analyzes the images of color,animal and machine,which convey Crane’s thoughts of war:war is full of chaos,brutality,and confusion,without any romantic elements or heroism. 展开更多

Stephen Crane(Stephen Crane,1871-1900),a famous American novelist and poet.The Red Badge of Courage,his masterwork,published in book form in 1895,has been widely acknowledged as a classic in American literary history.In most cases,symbolism is considered to be a technique used by Crane to convey its naturalistic theme.This thesis attempts to make a detailed analysis of the system of symbols in The Red Badge of Courage to show that symbolism is used by Crane to better convey his naturalistic ideas so that a better understanding and appreciation of the work can be achieved.Crane's symbolic style makes him become a pioneer modernistic writer who has influenced many later writers. 展开更多
