The twelve-animal zodiac series—rat, ox, tiger, rabbit, dragon, snake, horse, goat, monkey, rooster, dog, and boar—signifies a traditional Chinese concept of time structured in a cyclical order. The twelve animals are also linked to the art of fortune-telling that underlies human existence in connection with the changes of the universe. The use of the twelve zodiac animals as tomb furniture suggests they provided a cosmological structure for the afterlife.
