Historically, the Caucasus region during the Sasanian period was among the important parts of Iran. Many studies have been conducted by archeologists, historians, and linguists on this region. The book entitled Middle Persian Inscriptions of the Era of Khosrow Anushirvan in Darband, Caucasus (Dagestan) by Cyrus Nasrollahzadeh is one of the attempts to investigate this region through available inscriptions. 

Mythological themes reflecting the worldview and ideology of ancient societies have various applications. One of the applications is for rituals, which have a symbolic dimension. As if these themes are repeated in different societies, they are classified as archetypes. The archetype is derived from Jung's psychological theories, which is revealed in the form of a symbol in the context of myth, epic, and dream. Since dream and myth are the same in nature and structure, this study investigated Dumuzid's dream to find out the origin of mythological rituals in the third millennium BC in Mesopotamia. This study was conducted by a descriptive analytical method using Jung's archetypal approach based on library studies, the results of which showed a relationship between the myth of Dumuzid and rituals of Mesopotamia society, and the story of vegetation gods connected with the rituals of spring and fertility in nature as the source of collective mourning ceremonies and celebrations held every year in their memory. In fact, the rituals are cultural phenomena left over from the agricultural and prehistoric times in ancient societies.

Studying the elemental composition of coins does not only provide chemical information of the legal tender but provides insight into the manufacturing process, history, and economic state of the country during the minting year of the coins. The elemental composition of some Sassaian coins spanning from the years 582 to 591 AD have been analyzed using PIXE at the Bubansor physical lab of India and metallic the elements Ca, Fe, Cu, Ag, Au, and Pb were observed. The result The study of elemental composition of silver coins in Iran under the Sassanian period can help to explain the locations and identification of coins' mines. By determining not only major but also minor and trace element concentrations, the coin's compositions were used to deduce information both on the economic conditions under the different reigns. The aim of this work is to study the chemical composition of some Hormizd IV coins to show the economic situation and find any relation between the mines used for the extraction of silver and the actual silver coins minted at that time. Using the PIXE technique, the show that Hormizd IV king used almost Cerussite mines for their coins and are brought to light valuable information about the economy of the time.

In the east of Pahanvar Ray plain, we come to a fertile area (Pishwa/Varamin plain) which has provided suitable conditions for human habitation since the formation of human settlements until today. Due to the location of this plain in the north of the central desert and the border between the two cultural domains of the northeast and the center, the environmental condition and suitable altitude, which are the main factors for the formation of permanent settlements, and the possible existence of extra-regional connections of this area with the neighboring areas, a wide survey was conducted in this area of ​​the plain. It was concluded that during this archaeological investigation, 61 ancient sites from the Sassanid era were found in the east of Varamin and south of Peshwa. It is most likely that Varamin is considered a part of Ray State and based on the available evidence, it is possible that it is the main center of Ray State as well. According to historical texts and archeological data, the state of Ray was one of the important areas of human settlement during the Sassanid period in Iran. Historical texts mention Ray in the Sassanid period, and the number of sites attributed to the Sassanid period in the geographical area of ​​Varamin has not been found until today. Despite this, based on the prominent geographical location of the Varamin region and the references of the historical texts to the Ray state, this region was probably one of the important regions of the historical period in Iran. In the present article, an attempt has been made to describe the historical geography of Ray State in the Sassanid period, while using the archaeological data of the Sassanid period of Varamin, to draw a part of the archeology and historical geography of Varamin in the Sassanid period.

Situated approximately 3 kilometers south of Shushter, Gelālak is nestled between two branches of the Karun River: Gargar and Shatit. Gelālak is a locality within the extended site of Dastowā. Archaeological excavations in Gelālak (1986-87, 1987-88, and 1989-90) led to the discovery of a rich collection of tombs, sarcophagi, ceramic and glass vessels, ornaments, metal objects, seals, and coins dating back to the Elymaean Elymaean dynasty of the Kamanskiris.
