The Grivar inscription of the Davazdah Imam Mausoleum of Yazd is a thousand-year-old unique inscription with a monotheistic theme placed on an octagonal platform, which can be used as the basis for its analysis. The present article has tried to uncover the visual and formal measures implemented in this inscription using visual analysis, and it seeks to answer the following questions: "Which visual and representational measures has the designer used in the design of the Grivar inscription of the Davazdah Imam Mausoleum of Yazd? How and to what extent has it been used to instill a sense of unity?" In this qualitative research, which was conducted using descriptive-analytical method, and the data was collected through library studies and field surveys.

The results of data analysis showed that following the identical form, especially in the geometric and writing system, using small components in each system, following the common linear structure, the space of the same importance on the inscription, etc. are among the most significant visual measures used with different quantities and qualities in the inscription's design, which, as a whole, plays a role in inducing more monotheistic themes by creating a desirable visual unity.
