The study of potteries is always considered with different approaches in analyses The main problem is that none of these studies have dealt with visual contracts of a specific theme in order to distinguish archaeological sites. Accordingly, two main features were defined for research in the Visual contracts under study: Extent in different regions and times. The visual potential is to be defined as visual contracts and to have sufficient examples to recognize the characteristics of visual contracts.The condition for accepting visual contracts for each site was repeated in nearly a quarter of the pottery with the role of an ibex in the same areas.
A study of many motifs showed that, except for a few areas, ibex motifs in most areas could be defined as contracts or visual contracts based on one of the definitions of the form (either as a form or as an organizational and structural principle(. Contracts sometimes differed in the same area and at different times, and sometimes showed similarities in different sites and archeological sites over a close period of time. Also during the study, some visual conventions such as ibex urinating that had meaningful meanings were examined in different areas. Among the types of metamorphosis, deformation was the most popular method of representation in order to exaggerate the distinctive feature of the ibex form. In this way, the artist exaggerated by drawing one of the animal's limbs, making that organ the main subject. Exaggeration was represented by various types of pictorial conventions, and in general, the horn was more important to potters for exaggeration than any other organ. most visual contracts are methods to show movement, with 5 methods in areas represented.
