Abstract

The Shuduan《書斷》 by Zhang Huaiguan of the Tang dynasty comprises classifications of calligraphy that Chinese theoreticians still refer to. This article aims at considering the functioning and efficacy of such evaluations through a study comparing this work to other treatises and, when relevant, to the European tradition. Its main objective is to examine how Chinese aesthetic theory responded to new evaluative needs that appeared during this crucial period in Chinese history. Thus, it seeks to clarify the nature of the criteria adopted by Zhang Huaiguan for his gradings: are they material, ideological, aesthetic, or of another nature?
