The identity of the author has not yet been established, but the coherence of the style and the subtle symmetry of the narrative point to a single author. The British orientalist Arthur Waley, writing before recent research, in his Introduction to the 1942 translation suggested that the strongest candidate as author was Xu Wei, a renowned painter and member of the "realistic" Gong'an school of letters, urging that a comparison could be made of the poems in the "Jin Ping Mei" to the poetic production of Xu Wei, but left this task to future scholars.
