《大衍历》融通易学的文化阐释

A Cultural Interpretation of the Relationship between Yi-ology and Dayan Calendar

唐代僧一行主持编制的《大衍历》,具有“制历准备充分,注重实测与验证”“旁征博引典籍,进行辩证与精算”“援引《周易》经典,依‘大衍之数’立法”的特色,是古代易、历融通的典型实例。《大衍历》的编制,从总体思想观念到具体数值建构,都与易学文化紧密相关,体现出了哲学思想与科技文化交融的传统文化特色,具有深厚的文化蕴涵。

The Dayan Calendar compiled by Monk Yi-hang of the Tang Dynasty has the characteristics of"sufficient preparation for calendar making,emphasis on actual measurement and verification","extensive reference to ancient books,dialectical and actuarial calculations","citing the classics of the Book of Changes,and legislation based on the'number of Dayan'".It is a typical example of the integration of ancient Yi and calendar.The compilation of the Dayan Calendar,from the overall concept to the specific numerical construction,is closely related to the culture of Yi-ology.It integrates philosophical ideas and their comteporary technology,which is a characteristic of the traditional Chinese culture,and in this manner leaves profound cultural implications.
