Ziwiye, as one of the key sites for Iran’s North West Iron Age (Median kingdom), has many masterpieces kept in different museums and a long list of publications. The main part of this list consists of monographs that are written based on one or more limited objects from an out of context collection. There are few articles that comprehensively include the findings “attributed Ziwiye” and “came from excavation”. However, many articles have been published about Zavieh’s findings, but parts of this collection still remain unknown and do not receive enough attention. The corpus of bone arrowheads is one of them, some of which were found during archaeological excavations while others came to museums from antiquities dealers. These include: the Metropolitan Museum of Art in New York, Musée du Louvre in Paris, the National Museum of Iran in Tehran, and the Sanandaj Archaeological Museum. This article aims to introduce and categorize 51 bone arrowheads. Some of these were registered as ivories, but our research concluded that all of these were made of bone. In few instances, the production manner prevented the proper identification of bone versus ivory. Another examined point in this research is whether such arrowheads were produced for actual warfare or for prestige and symbolic use in ceremonial events considering their bone material. The examined samples from other sites show that bone can be hard enough to penetrate game and human body even with light protection such as archery. Bone for making arrowheads was used for hunting big games and some tribes still use them.

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.

The final goal of this research is to investigate the design of Qajar women's clothing in different periods. In the first step, the question arises whether the cover can be a language. Then this research seeks an answer to the question of what messages in the form of language mean. Therefore, in the current research, the above issue has been analyzed by a case study of Qajar women's clothing and using a descriptive-analytical qualitative research method. Findings: This study shows that the clothing of Qajar women can be considered a single language of signs. In deciphering this language, concepts such as women's attention to religious foundations, gender inequality, and patriarchal view in society, the value of wearing Iran's old traditions, as well as the desire to move towards westernization and fashionism of Europeans can be inferred. The results of this research show the importance of the role, color, code, sign, symbol, and finally language in the field of women's clothing in the Qajar period.  

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.

Tappeh Bazgir is one of the most important archaeological sites of the Late Bronze Age in northeastern Iran. At this site, a hoard of 759 Bronze Age copper-alloy objects with an approximate weight of more than two tons was excavated. This find is unique in terms of volume and the extraordinary finds it contained. This archaeological hoard was discovered by chance in 2001, and in 2010 a rescue excavation was carried out at the findspot. This hoard had been buried in the virgin soil and deliberately concealed under a residential floor in the Late Bronze Age. The objects recovered served different purposes; they include agricultural and household implements, tools, ceremonial objects and a variety of weapons. The artifacts were all located next to each other in a pit and had been arranged in a regular manner. There were also three shields among these objects. They had been placed next to each other under basins with gutter-shaped pipes and on top of daggers, hatchets, axes, two-pronged forks, and stone rods. These weapons had evidently been positioned at close to the domestic objects. The shields are of strikingly similar shapes, but they differ slightly in the number of openings and bars. Up to now, no similar shields have been found at any other archaeological site. These shields seem to be the oldest shields excavated in Iran. XRD and XRF analyses revealed that one of the shields and other objects of the hoard were made of cast copper-alloy, and they were subjected to cold forging/hammering later.

The study of the elemental composition of silver coins minted in the Tabriz during the Qajar period can help to investigate the socio-economic situation of that period. In this case study, Proton- Induced X-ray Emission (PIXE) analytical technique has been applied to twenty-eight Qajar silver coins selected from a private collection. the purpose was to study and investigate the changes in silver elements in Qirans of Nasser al-Din Shah Qajar in Tabriz mint. The metallic elements Ag, Cu, Fe, Pb, and Au were observed. The results show that the content of Ag the main constituent of the coins varies from 90.07 to 82.88%. this significant variation in the content of the major constituent reveals the economic difficulties encountered by the dynasty. The results, which are shown by using the PIXE technique, brought to light valuable information about the economy of the period under study.  

This paper will compare the characteristics of four ancient Iranian, copper alloy weapons. These weapons are from private collections in the USA at the time of examination. The first two weapons fall into the category of dirks (or daggers). This characterization is based on the overall length of the weapons in question. For comparative purposes, a dagger reaches 30 cm, a dirk is a classification for weapons with overall lengths of 30-50 cm, while a sword would have an overall length of over 50 cm. Because precise archaeological data is absent for these pieces, we examined short-term provenance and microscopic analysis, together with stylistic components to verify the authenticity and general cultural origin of each specimen. The hilt of each weapon is bordered by a ridge, or flange, on both sides that would have allowed for an organic or stone inlay to make the grip more comfortable and functional, as well as adding to the aesthetics of the piece. The pommels of these weapons all have a similar, crescent shape. Weapon 2, has not only a crescent-shaped pommel but also a more pronounced, crescent-shaped guard. Both of the dirks (weapons 1 and 2) have roughly triangular blades. However, the blade of weapon 1 becomes narrower near the guard while the blade of weapon 2 does the opposite and flares out near the guard. Microscopic examination of the patinas confirms the ancient origin of each piece, however, subtle differences in the patinas suggest that the alloys and/or the burial conditions of each were potentially different. This would be an area where further study would be warranted.
