A study of hidden and obvious angles of Iranian works of art, including the discovered artifacts of the ancient Marlik region, shows the rich heritage of this land. The ancient hill of Marlik, despite its tools and utensils, and especially its clay sculptures, is still explored due to its special elegance and beauty. The aim of this study is to have a measure of fit and linear range in Marlik pottery and to get acquainted with its hidden angles. In this regard, the question arises as to how the use of golden proportions and the visual element of the line (as a range) appear in dimensions and sizes of the clay figures. In this regard, 6 index statues have been excavated from Marlik Cemetery and the results showed that 3 clay statues follow the golden ratio of √2, √3, √4 and √5. And they have a good linear range and balance, exaggeration and harmony can be seen in them. In this process, the other 3 statues are not attractive in terms of size and dimensions and do not have the elegance of construction and design. In addition, the two factors of proportionality and linear expansion are in complete unity, and the role of positive and negative space to achieve balance is obvious. The research method here is descriptive-analytical and in the data analysis, the golden proportion approach has been used, as well as the collection of information is documented.
