表现主义一般是指二十世纪初发端于德国的一场文学及造型艺术的创作活动和思潮。纵观人类的艺术发展史,没有一个思潮是孤立发展的,它往往都是在一个艺术领域兴起之后整个席卷了文学、音乐、造型艺术等多个艺术领域。表现主义也亦复如是,然而,在席卷整个艺术门类的同时,本文主要对绘画和戏剧这两个在时间和空间上并不相通的艺术领域之间相互融合,互为支撑的原因进行探究。 Expressionism generally refers to the creative activities and thoughts of a literary and plastic arts originated in Germany in the early twentieth century.
