The theme represented on this jade boulder, the largest piece of jade carving outside of China, refers to an event that occurred on March 3 in the lunar calendar of 353. Wang Xizhi (303-361), a scholar official and one of the most esteemed Chinese calligraphers of all time, together with 41 renowned scholars and officials, gathered at Lanting or Orchid Pavilion in Shaoxing (in present-day Zhejiang province), celebrating the Spring Purification Festival. The scholars engaged in a drinking contest: Wine cups were floated down a small winding creek as the men sat along its banks; whenever a cup stopped, the man closest to the cup was required to empty it and write a poem. In the end, 26 of the participants composed 37 poems. Wang Xizhi was asked to write an introduction to the collection of these poems. Written in semi-cursive script and known as Preface to the Poems Composed at the Orchid Pavilion (transcribed on the top of the mountain by the Qianlong Emperor), it is the best known and most copied calligraphic work in art history. While the mountain image alone is enough to convey a close association between the jade sculpture and many painted landscapes, the Qianlong Emperor's seal and poem carved at the top on the other side of the boulder reinforces the idea of the jade mountain as a three-dimensional landscape painting.
