The relative and long-term stability brought about by the Safavid government in Iran made urbanization and its requirements to be reviewed, next to the issue of public health. Some physicians began to run new experiments and produce treatises. One of these outstanding treatises is the Risala Ateshak, written by Imad al-Din Mahmoud bin Masoud Shirazi. For the first time, by writing an independent treatise, he described the symptoms, methods of prevention, and treatment of syphilis. To him, the treatise issued before his, except that of Baha'u'l-Razi, were not discussed and were considered a phenomenon from abroad (the West). He sought to explain the manners of transmission, prevention, and treatment of this disease in different temperaments through the available methods, which were mostly based on herbal medicine. He also expressed his belief about the effectiveness of consuming Chinese wood in treating this disease. The accuracy of this treatise's contents and its writing period makes it clear that syphilis is not an imported disease contrary to the idea that existed. The reason for our ignorance of its existence was the inability to distinguish it from other diseases.

Luristan is located in the Central Zagros Chains and it plays an important role in the events of the first millennium BC. Therefore, archeological and historical studies of this region lead to a better understanding of the events and the role of Lorestan in this period. The purpose of this research is to investigate the role of Lorestan in the first millennium BC based on historical and archeological sources. This research was done with a descriptive-analytical method with a historical approach. The Results show According to the Assyrian documents, Greek and Roman sources an ethnic group lived in the Zagros Mountains. Their land more probably was bigger than the administrative borders of Lruistan. Presumably, it should be somewhere between the Greater Media and Susa or Chaospes River. Luri is the common language of these peoples in this area.

The cavalry battle scene depicted on the Himyarite bronze plaque, being possibly a part of horse harness, reveals some relation with Iranian iconography of Parthian and Sasanian times. The relation is not direct and there are numerous differences with the Iranian fighting scenes. The composition does not directly refer to any of the Parthian or Sasanian battle reliefs or toreutics and seems to follow earlier, Hellenistic traditions, enriched by the Iranian and local detail. The direct confrontation, without immediate determination of the victorious and defeated sides, was avoided in Iranian iconography which aimed in glorification of royal heroism, being always victorious and only victorious cosmic power. The differences between the equipment of the depicted personages, clashing in cavalry combat, allow to identify the scene as a local version of classical amazonomachia with some Iranian iconographic elements added. Generally, the long lances were in Parthian and Sasanian times perceived as Iranian element of warfare and included to Iranian iconography of royal power, even if the tactical idea of employment of long lances, most likely, reached Iran with the Macedonians. It is possible that the female warriors in capalin/morion types of helmets of post Hellenistic origin clash with the warriors wearing scale armour covering entire body. The possibly-female warriors are shown in garments or nude and they seem to refer to iconographies of Athena-type goddesses in oriental environments. The latter motif of naked Amazon in combat is not popular in main-stream classical art but is occasionally attested. Scale overalls may refer to Roman imagery of heavy cavalry of Sarmatian origin. The piece, together with another rock relief, prove knowledge of Iranian-type heavy cavalry among Himyarites who attempted to follow or imitate the prestige of both great empires of the time.
