The Sun is one of nature's greatest powers capable of being directly sensed by humans. It symbolizes brightness and warmth and is the source of life and energy. It is also one of the earliests of worship in the polytheistic societies of primitive man. The first civilizations of humankind were based on agriculture and the mean- ing and significance ascribed to the Sun varied from culture to culture. In the grainbased societies of Asia, jade, silk, and lacquer all appear as early as the Neolithic period. These all belie ancient people's respect for brightness, which is a reflection of their worship of the Sun. The symbol of the Sun passed through three early stages: (1) a direct pictorial representation of the Sun; (2) a combination of the Sun and other elements, such as birds, plants, and animals, from nature, and (3) an anthropomorphication. The anthropomorphosis of the Sun signifies its becoming one deity among many, as opposed to being the main deity, and the shift toward ancestor worship, as opposed to the worship of nature. The Ti and Tien of the Shang and Chou dynasties are most likely related to this trend. Different Sun gods are products of different conceptions of nature and the world and result from different modes of production. Thus, the Sun gods found throughout Asian cultures vary considerably from those of American natives and ancient Western cultures. They are products unique to Asia.
