역위(易緯)「통괘험(通卦驗)」의 성립시기와 괘기설(卦氣說)

Abstract

The purpose of this paper is to figure out the advanced theory of Qua Qi and the formative period of Tong Gua Yan (通卦驗) in Yi Wei (易緯), and investigate the relationship between the two representative Meng Xi (孟喜) and Jing Fang (京房) of numberology. Based on the assumption that each chapter could have been scattered around the country before called for Yi Wei (易緯), this paper discusses about the possibilities of Tong Gua Yan (通卦驗)’s first and the second books being written in the early part of the Western Han Dynasty. Also, Tong Gua Yan (通卦驗)’s Qua Qi as the fruit of astronomy and Changes ( 易 ), advanced studies in the Western Han Dynasty, along with next to Ji Lan Tu (稽覽圖) are considered as the most important book in Yi Wei (易緯)’s Qua Qi and fortunetelling. Tong Gua Yan (通卦驗) consists of the four hexagrams (四正卦), and the eight trigrams(八卦)’ Qua Qi theory where the traditional understanding and the perspective about eight trigrams and the eight Solar Terms in the second book of the Tong Gua Yan (通卦驗) are commonly found from the early books of the Western Han Dynasty. Therefore, the predominant academic view that the eight trigrams’ Qua Qi theory was developed and inherited from the Meng Xi (孟喜) and Jing Fang (京房)’s numberology is doubtful, rather the author’s view is that Meng Xi (孟喜) has inherited the four hexagrams theory of the Tong Gua Yan (通卦驗). Finally, the eight trigrams in Tong Gua Yan (通卦驗)’s second book are connected to the Nine Palaces’ Qua Qi theory(九宮卦氣說), which again raises a question about Zheng Xuan(鄭玄)’s interpretation of it into the twelve waning and waxing hexagrams (12消息卦).
