The article reviews chivalry traditions, developed in ancient Iran, and their transition and transformation to the country’s post-Islamic history. The author analyses the cultural mechanisms, which provided this movement, and argues that its roots and prerequisites should have taken place in Great Khorāsān at the very turn of the ‘Abbāsid revolt in the middle of the century CE. This was a period when an external call activated forces and facilities, preserved in the stratum of Iranian knights, to become the basis for the later military evolution within the new circumstances. The cultural importance of Khorāsān for the Iranian state and rule at the turn of the Muslim era is reflected in written texts. The early muslim period in Great Khorāsān was a special time as Iranian predominance mingled with multicultural traditions in the boundary region. The topic is presented in a wide context including Irasnian literary, artistic, and artisanal sources, helping to visualize the historical backdround of Iran. This is based on philosophical doctrines for Iranian cultural developement proposed by contemporary scholars.

Dakkato al-Qadaa is a place in the Kufa mosque where, according to historical narration, Hazrat Ali (pbuh) used to judge and many of his judgments were narrated in this place. The study of this place is important in terms of the role that mosques have played in various aspects of the spiritual and material life of Muslims. This place can be researched in several ways: the historical reference of the place; the ancient aspect of the remaining signs; Jurisprudential rulings related to judgment in the mosque. According to the studies that were carried out, such a place definitely existed in the history of Islam, and even now there are signs of it in the mosque of Kufa, which is honored and celebrated by the Shiites of the Prophet, which is one of the characteristics of The richness of Islamic civilization is in terms of judicial functions. The knowledge of this specific place depends on the knowledge of the mosque of Kufa on the one hand and the examination of the place of mosques in the Islamic culture and civilization and how proceedings were conducted in the early ages of Islam. This article is organized with a descriptive and analytical method using the remaining written documents and physical works available in the place.

A recent trend in photogrammetry is the use of unmanned aerial vehicles (UAVs) for photogrammetric purposes. A data acquisition sensor is mounted on an unmanned aerial vehicle to collect data during short-range aerial photogrammetry from a low altitude. This system is capable of filling a significant gap left by other conventional methods in the field of map production. The improvement in processes over conventional methods is the basis for this method's effectiveness. A significant portion of valuable data is obtained after the first processing stage as a result of automation in all data production processes. Real orthoimages, 3D models, and a detailed point cloud of the area are all included in this data. Drawing and mapping maps have gotten much easier, more accurate, and quicker thanks to modern software. We are looking for ways to use these kinds of methods in documenting the archaeological heritage in this article by applying this method at the historic site of Susa. The experts and practitioners in this field will benefit from this method, which is a collection of the most effective techniques for geometric measurement, analysis, and interpretations related to issues raised in archaeology.

A study of the arrow guide or nāvak in Iran. It covers the technical aspects of arrow guides and how they may have entered Iran. In Persian, arrow guides are called nāvak and their projectiles are called tīr-e nāvak. However, sometimes nāvak is used for the arrow as well, and even the bow. It also covers how outside cultures viewed Iran as a source of innovation in the further development of these devices. In Arabic they are called majrā and this is the term most familiar in the west due to two important translations of Arabic archery manuals into English, Arab Archery and Saracen Archery, but they were mentioned earlier as nāvak in an English translation of part of the Hidāyat ar-Rāmī, where they were mistakenly described as crossbows. Essentially, an arrow guide is a partially closed tube used with a bow to shoot a short arrow drawn much farther than its length would normally allow. This produces a projectile that has increased velocity and less friction through the air than a regular arrow. The arrow guide has had a long history in Iran, probably entering in the last years of the Sasanian Dynasty, surviving the Arab conquest and persisting until the gradual takeover by firearms. It was fertile ground for invention with many variations being spread across the Islamic world. The persistent association with Iran in Arabic archery manuals reflects the perception that much of its development was tied to Persian users. Here, Persian and Arabic sources are examined. Reference is made to original artefacts and reconstructions.

In recent years there has been a growing interest among historians, historical martial artists, reenactors, and those who are interested in Eastern culture as well as in Persian offensive and defensive weapons to have a more detailed study of armor. The change in the paradigm of defensive weapons throughout Western Asia (the last quarter of the 15th to the first quarter of the 16th century) has not yet been fully investigated. Reconstruction of mail-and-plate armor from a period between 1540-1650 CE is quite challenging as most museums or major private collections do not have a complete set. Based on a detailed study of existing sets of joshan armor and several technical assumptions related to the design of this type of armor, the present study tries to reconstruct a fully protective complex of a joshan armor that was worn by a noble Persian warrior. The purpose of the following article is to reproduce a Persian mail-and-plate armor from a period between 1540-1650 CE in its original size and design with its inherent properties and qualities. Different existing sets of this type of armor from museums are studied and compared to different miniatures and literary sources. Based on the collected information gained from theoretical and practical research, the article presents a historical armor design and provides advice on the practical reconstruction and production of such a set of armor. Armor masters were looking for the best combinations and ratio of plates and mail armor in one set. They were experimenting with the shapes and sizes of plates, the number of holes, diameters, geometry, and method of ring interconnections. Characteristic of the armor of this period is rather large plates and a small number of their rows (3-5 rows on the chest/back), a small overlap of the plates in a row, basically only the same standard plates are used, large mail rings (inner diameter about 10 mm).

The ability to recognize and compare shapes and understand the concept of proportions is one of the first human findings from environmental geometric data. And certainly the formation of geometry as a science of recognizing the arrangement of lines, shapes and levels and proportions leads to the definition of golden proportions in the mathematical sciences as a new way of organizing shapes and forms. Golden and geometric proportions are effective as a determining element in the scale of spatial forms, and the formation of spatial forms by not using or misuse of geometric proportions is due to functional and psychological interactions on human perception and cognition. Which causes the construction and formation of scales and proportions of the environment and the emergence of psychological effects due to human activities in the environment. And then the abnormal effects and environmental dysfunction on the saccade system of the human eye and as a result the feeling of fear and lack of belonging to the place interacts. On the other hand, nature as the raw material of creation, and the principle and mother of man, which causes him to model the proportions in nature. Understanding the laws governing the relationships between elements and spatial shapes leads to the formation of geometric and golden proportions in the spending of space. Because knowing the symbol of shapes, proportions and scales in the world of meaning and kingdom is reminiscent of the divine order in all dimensions of the world (even in astronomy). Therefore, evaluating the values ​​of spatial proportions in nature as the bedrock of human life and the pattern of psychological perceptions, leads to the adoption of human activities. Also, the study of human needs on a mental and psychological scale from the perception of the environment causes the recognition of scales and dimensions by human visual senses, which leads to the perception of the correct golden and geometric proportions through Sakadi eye movements and psychophysical sciences. . Certain ratios can also be observed in the creation and design of various shapes in nature. These relations are those geometric relations that have immaterial roots and follow the spiritual and supernatural principles, believing that their subject is sacred, and have a symbolic language and spiritual characteristics. In the traditional world, geometry was inseparable from the other four Pythagorean sciences, namely arithmetic, music, and astronomy. And traditional geometry is also associated with the symbolic composition and shapes of space. To this end, the study of the effect of golden and geometric proportions on human visual perception of the architectural environment based on the sense of belonging to the place, causes visual quality to increase the sensory richness of the place and achieve human values ​​and criteria in the sense of belonging to the place and human needs. To be considered by the architect. In this research, with the perspective of this identity and the interaction of geometric and golden proportions and the sense of belonging to the place, the criteria and indicators of the research have been studied and the results have been presented in the form of tables and diagrams.
