Function and Meaning of the Ambulatory of Centralized Plan in the Early Christian and Early Medieval Church Architecture

本研究旨在通过建筑调查和分析中世纪早期教堂中Spolia的配置，阐明流动通道的功能和意义。结果如下：1。流线和中央中殿有不同的空间顺序，这体现在Spolia的配置上；2. 尖顶的轴线和建筑入口的轴线斜交叉，所以人们在入口后绕着弧形移动，然后进入中央中殿。

This study aims to clarify the function and meaning of the ambulatory through the architectural survey and the analysis of the disposition of Spolia, in some early medieval churches. Results are as following : 1.the ambulatory and the central nave have a different order of space showed by the disposition of Spolia ; 2. the axis from Apsis and one from the entrance of the architecture cross obliquely, so people moved circularly through the ambulatory after the entrance, then entered to the central nave.
