Seonya theory(宣夜說) was one of the most important metagalaxy model in the ancient times. Unlike the other important metagalaxy model, it had the concept that the sky is not in the solid state but is just the infinite space which is full of gi(氣). But Seonya theory, though it had partially the superb academic thought, it had gradually become the forgotten thing among scholars in the ancient times. Since then, once forgotten Seonya theory was reconstructed again in Song(宋) dynasty, and Jangjae(張載) did the main role at that time. In the historical sequence like this, we need to take notice of one thing that "Hwangjenaegyeong(黃帝內經)" had worked on Jangjae as the origin of his sunya theory. So we also need to take notice of one thing that "Hwangjenaegyeong" is just a rare document that comprises the academic thought of Seonya theory which had once been forgotten in ancient times. Based on the historical situation like this, this study is focused on the idea that the discuss on the Jangjae's Seonya theory would be a good way to think of the cosmic theory of "Hwangjenaegyeong" and the theoretical thought derived from them. So this study will first look into the academic characteristics of Seonya theory of ancient times and of "Hwangjenaegyeong" and through the study on the academic characteristics of Jangjae(張載)'s Seonya theory, will also think of the significance of the thought of Jangjae's Seonya theory that would be some help to the research on "Hwangjenaegyeong".

This paper aims to examine the meaning of 'Xuan(玄)' in the cosmology and astronomy, especially in the view of Yang-xiong(揚雄) and Ge-hong(葛洪). 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. In this way, their view point of the cosmology is comprised of cosmogony & astronomy. With this perspective, they are going to found the system of their own philosophy.
