Sasan (Middle Persian 𐭮𐭠𐭮𐭠𐭭 Sāsān > Persian ساسان), considered the eponymous ancestor of the Sasanian (or Sassanid) Dynasty (ruled 224-651) in Persia, was "a great warrior and hunter" and a Zoroastrian high priest in Pars. He lived sometime near the fall of the Arsacid (Parthian) Empire in the early 3rd century. Identity of Sasan Medieval sources There are many slightly different stories concerning Sasan and his relation to Ardashir I, the founder of the Sasanian Empire. The northern Iranian historian Tabari mentions that Sasan married Rambehesht, a princess of the Bāzarangid family, the vassal dynasty of Pārs, and that Sasan was a grandfather of Ardashir I, while Papak is named as Ardashir I's father. According to the Pahlavi book of Karnamak-i Artaxshir-i Papakan, Sasan's wife was a daughter of a nobleman called Papak. The marriage was arranged by Papak after hearing that Sasan has "Achamenian (Achaemenid) blood in him". Their son was Ardashir I. Sasan vanishes shortly after Ardashir appears in the story and Papak is "considered the father of Ardashir".
