天地间的一切事物都是以时间和空间这两种形式存在的。艺术当然也不例外。但不同的艺术种类的时空存在形式是有很大差异的:音乐、诗、小说等是一维的时间艺术,绘画、书法是二维的平面艺术,雕塑、建筑等是三维的立体艺术,戏剧则是空间三维加上时间这一维度的四维时空艺术。舞台上的演员是立体的,立体的演员需要运动,而运动又必须在时间维度中展开和绵延,所以说戏剧的存在方式是时空共在的。 Everything between heaven and earth exists in both time and space. Of course, art is no exception. However, there are great differences between different forms of art in space and time: music, poetry and fiction are one-dimensional art of time. Drawing and calligraphy are two-dimensional art, sculpture and architecture are three-dimensional art, drama It is the four-dimensional space-time art in the dimension of space three-dimension plus time. Stage actors are three-dimensional, three-dimensional actors need exercise, and exercise must be carried out in the time dimension and stretches, so the existence of drama is time and space.
