The cosmology of the ancient China has opened a discussion about the Tian(天), through the discussion about the celestial structure, the structure and the location relation of the heaven & earth, in the Han-dynasty has been found a systematic theory. But in the ancient Chinese philosophy, the cosmology has been developed in the field of the astronomy & the Oriental calendar. In this context, Yang-xiong(揚雄) and Ge-hong(葛洪) have founded the system of the cosmology, it is as in the following. First, Yang-xiong criticized sharply the theory of Gaitian(蓋天說) and advanced the theory of Huntian(渾天說). And Ge-hong support the theory of Huntian(渾天說) and also accepted the theory of Xuanye(宣夜說). Second, Yang-xiong(揚雄) and Ge-hong(葛洪)'s cosmology is regarded as the theoretical premise of their cosmogony. As the discussion about the celestial structure, the structure and the location relation of the heaven & earth, both scholar discussed about the cause of creation, the differentiation process. And in the this context, they founded the cosmology as the concept 'Xuan'. Third, the concept 'Xuan' in the both scholar forms a philosophical system. Yang-xiong insisted that the concept 'Xuan' is the basis of the universe, the human-being and the society. While through realizing the concept 'Xuan', Ge-hong tried to pursue the human-being's agelessness and the eternal life.

This paper aims to examine the meaning of 'Xuan(玄)' in the cosmogony, especially in the view of Yang-xiong(揚雄) and Ge-hong(葛洪). The concept 'Xuan' is thought to have originated in the XianQin text Laozi & Zhouyi. After the XianQin period, this concept has been defined as philosophical concept, and it has a variety of meanings. This paper discussed about the cause of creation, the differentiation process, and the existence principle, within the cosmogony of Yang-xiong & Ge-hong. First, the cause of creation in the Yang-xiong is efficient cause in the state of the elementary substance, but also is the principle that is applied to the phase of the creation. While the cause of creation in the Ge-hong is comprised of the cause of the creation and the existence principle. Thus, the meaning of the concept 'Xuan' in the both scholar is different from the matter monism. Second, the concept 'Xuan' in the both scholar contains the tendency of cosmogony and ontology. Yang-xiong maintains the cosmogony, but he also hold on the rudimentary view of ontology. While Ge-hong display a tendency of ontology. Third, Ge-hong accepted the view of Yang-xiong and he developed the meaning of the existence principle. And finally, the concept 'Xuan' in the both scholar forms a philosophical system. Yang-xiong insisted that the concept 'Xuan' is the basis of the universe, the human-being and the society. While through realizing the concept 'Xuan', Ge-hong tried to pursue the human-being's agelessness and the eternal life.
