The artifact studied in this paper is a bimetallic sword made of bronze handle and an iron blade, which was excavated from the Tol ancient cemetery, located in Talash city, Gilan province, in 2001 by Mohammad Reza Khaltabari. This research aims to study the technology and pathology of the mentioned object by conducting comparative and archeological studies using the library method, conducting technological studies using the laboratory methods of radiography, metallography, and microstructural observations using a scanning electron microscope (SEM-EDS). The phase analysis of corrosion products was done by X-ray diffraction (XRD), as well as knowing the manufacturing method and identifying the types of damage and corrosion. The result shows that this work belongs to the Iron Age. Also, the tests performed on the two parts of the handle and the blade showed that the material of the iron blade is iron-carbon alloy. The amount of carbon in different parts of the body of blade is not the same and the handle is made of bronze alloy with casting and hammering techniques. It also has a galvanic corrosion effect.

The lifeways of mobile human societies are a field investigated by anthropologists and archaeologists. Mobility is considered an effective way of foraging and resource production among human societies (for hunter-gatherers, pastoralists, and farmers, respectively). Various classifications regarding the mobility patterns of human societies have been proposed so far. As of today, the majority of archaeologists use Murdock’s multi-purpose classification which divided mobile human societies into four groups: (1) Nomadic societies, (2) semi-nomadic societies, (3) semi-sedentary societies, and (4) sedentary societies. But some societies have characteristics that do not allow them to be placed in one of these groups. For identification of these unclearly defined societies, the authors will refer to 5 criteria of demographic dimensions: Mobility, number of movements, movement distance, residential criteria, and lifeway. For instance, it was not until 2003 that archaeologists began to recognize the intermediate trajectory of nomadic pastoralism from early village-based herding to the formation of full-fledged pastoralism in the western part of Central Zagros. Extensive study of pastoralist communities, however, can be used for the identification of several intermediate stages of the 5 criteria. Current archaeological evidence in most of the early Neolithic sites in Central Zagros such as Qazanchi, Sheikhi Abad, Sarab, Asiab, and Guran, unlike the Levant region which was settled in the Epipaleolithic (Natufian) period, indicates that these sites are seasonal. So how can we explain the mobility of human societies in the proto-Neolithic period of Zagros? As a result, the authors try to use these criteria to identify the intermediate stages of sedentarism in Zagros, from mobile societies in the Epipaleolithic period to sedentary societies in the late Neolithic period. For this purpose, the authors have studied the mobility patterns and residential criteria of human societies in the cultural landscape of Hawraman. The research was conducted in two seasons, in the summer of   2016 and the summer of 2018, respectively. At first glance, the patterns of mobility and lifeways of human societies seemed homogeneous and identical in the cultural landscape of Hawraman. But with a deeper analysis, Four main mobility patterns were identified. The patterns include (1) single-stage agriculturalist residential mobility in Koh-e-Takht, (2) multistage pastoralist residential mobility in Kosalan and Shahu Mountain, (3) logistical mobility (transhumance) in Javeh River, and (4) logistical mobility (based on cultural exchanges) all over the Hawraman. The patterns show that the Zagros societies did not become sedentary in a single stage. Therefore, semi-sedentary societies with residential mobility and semi-sedentary societies with logistical mobility can be placed in the intermediate stages.
