The survey of module in Achaemenid architecture, case study: The palace of Apadana and the hall of a hundred-column

The survey of module in Achaemenid architecture, case study: The palace of Apadana and the hall of a hundred-column Achaemenid era is one of the glorious eras of culture and civilization in which the art and architecture culminated its peak. Relying on other civilization's legacy, Achaemenid architecture obtained a singular, sophisticated and an unforeseen module which consisted of the application of hidden grids and brick-based modules which were adopted by their neighbors prior to Achaemenids. This paper focuses on the survey of Achaemenid architectural module in Persepolis. Applying the descriptive research method, this research has been complied with the help of documents, maps and field surveys, meanwhile, the data has been analyzed using Matlab and AutoCAD software. This article tries to respond to such questions, including: the basis of Achaemenid module formation, the extent of Achaemenid inspiration from other common module systems and the survey of common modules in The palace of Apadana and the hall of a hundred-column. According to the results, it is apparent that Achaemenid module is based on the dimensions of the bricks (standard brick of 33˟33˟13 cm) thereby, forming a brick-based module. In addition, this module seems to have been adopted from Babylonian brick-modules and has been well inspired by Geek length measurement systems. Moreover, two common modules in the above-mentioned palaces are Cubit and The Royal Cubit, which are all based on the human body dimensions.
