Anonymous Founder of Agriculture and Leader of the Deghani

In Iranian mythology, we rarely find the name of Wekard. In the few remaining texts from pre-Islamic Iran, it is briefly mentioned that he was Houshang's brother and the founder of agriculture, which was also called Pishdadi. In Islamic texts, although he is mentioned as a prophet, there is not much news about him. But Abu Rihan al-Biruni is one of the few writers who has paid more attention to his life and his character that based on some theories suggested about his name, origin, duties and his relationship with social classes. Abu Rihan al-Biruni by equating dehghani and writing, has considered the dehghani as the dignity of the Dibiris class and has considered the star of Mercury to be the special star of writers and dehghani. However, in this article it has been tried to introduce Dehghans and to examine their role in transmitting the culture and literature of ancient Iran to the Islamic era and their relationship with the Debirs, as well as to the educated class of Iranian society. In addition, by analyzesing the role and position of Wekard in ancient times, we try to find out the causes of the anonymity of this mythical character.
