Kal-i Jangal Parthian carved stone

Khorasan as origin of Parthian questionably faces lack of historical remnant of Parthian. Discovering Birjand Kal_i Jangal Parti carved stone and epigraph in 1330 as one of the scant remnants of this era is very significant. In this paper we tried to present a new and spacious analysis of this matter considering all the researches done in this field. Thus considering stone carved that shows battle arena between a warrior and a lion which this kind of arts in ancient Iran before and after Parthian era was rampant, we tried to analyze stone carved comparing with other remnants such as Lakh-i Mazar Parthian and Elymais tang-i Sarvak stone carved. Also we want to investigate politicians perusing titles used in Parthian epigraph from political service aspects.
