也许在研究表演史时遇到的两个最大困难是:表演按其性质而言,是一种很短暂易逝的艺术形式;而在这种形式中,艺术作品和艺术家又是不可分离的。表演是短暂易逝的——它是一种生存时间很短的艺术形式,通常的时间长度也就是一次演出——这种艺术包含在演出中,而直至20世纪之前,这种艺术始终无法加以记录。人们可以看表演,承认它是艺术,之后也可以写到它,但这种回忆并非艺术本身,表演是无法保存 Perhaps the two greatest difficulties that may be encountered in the study of performance history are that performance, by its very nature, is a transitory and perishable art form in which works of art and artists are inseparably separated. The performance is ephemeral - it’s a short form of art that lasts for a long time - it’s included in the show, and it was not until the 20th century that the art was never done recording. People can watch shows, admit that it is art, and later write to it, but the memories are not art itself, the performances can not be saved
