The original sixteen lohan or guardian arhats were enlightened individuals of Indian origin ordered by the Buddha to stay in this world to await the advent of the coming Buddha Maitreya. These sixteen, from an initial grouping of five hundred, were later joined by two more sinicised additions to from the Chinese set of eighteen, the jolly monk P'u-t'ai and Ta-mo-to-lo (Dharmatrata). The theme of lohan crossing the sea traveling from the legendary island of P'eng-lai in the eastern sea, to visit and influence mortal men, became a popular religious theme in the late Ming. The group is depicted here among strange sea monsters and demons in withering waves with exotic animals like the tiger, elephant, lion, dragon, Fu dogs, fish, winged horse, along with old sages and long-haired attendants.
