For 1,300 years, Chinese calligraphy was based on the elegant art of Wang Xizhi (A.D. 303-361). But the seventeenth-century emergence of a style modeled on the rough, broken epigraphs of ancient bronzes and stone artifacts brought a revolution in calligraphic taste. By the eighteenth century, this led to the formation of the stele school of calligraphy, which continues to shape Chinese calligraphy today.
