「四縱五橫」是唐宋以降道教法術中較為重要的訣法之一，其源頭似可追溯至秦漢出土文獻中的「直五橫」、「五（午）畫地」等說法。考察道教「四縱五橫」觀念的起源必須充分借鑒和利用最新出土材料及其研究成果，才有助於了解這一說法的理論源頭和發展脈絡。我們在論述中將側重於道教文獻之角度，著重分析道教「四縱五橫」觀念的演變過程，力爭還原道教對方術「四縱五橫」說的吸納、改造之軌跡及二者的區別與聯繫。

”Sizongwuheng” has been one of the important formula methods of the Taoist spell since Tang and Song Dynasties. We can trace the source back to the statements of ”Zhiwuheng” and ”Wuhuadi” in the Qin and Han Dynasties unearthed literature. In order to promote the understanding of the theoretical source and development source about the idea of ”Sizongwuheng” in Taoism, we must make full use of and draw lessons from the newly unearthed materials and research achievements during the course of investigating the origin of the idea of ”Sizongwuheng”. In this paper, laying emphasis on the perspective of Taoist Literature, we will focuse on the analysis of evolutionary process of the idea of ”Sizongwuheng”, and strive to restore the process that Taoism absorbed and transformed the idea of ”Sizongwuheng” and the difference and connection between them.
