Context_1 : Bozorgmehr-e Bokhtagan (Middle Persian: "Wuzurgmihr ī Bōkhtagān"), also known as Burzmihr, Dadmihr and Dadburzmihr, was an Iranian nobleman from the Karen family, who served as minister of the Sasanian emperor Kavadh I (498-531), and later as Grand Vizier under his son Khosrow I (reign 531–579), and then as "spahbed" under Hormizd IV. According to Persian and Arabic sources, he was a man of "exceptional wisdom and sage counsels" and later became a characterisation of the expression. His name appears in several important works in Persian literature, most notably in the Shahnameh. The historian Arthur Christensen has suggested that Bozorgmehr was the same person as Borzuya, but historigraphical studies of post-Sasanian Persian literature, as well as linguistic analysis show otherwise. However, the word "Borzuya" can sometimes be considered a shortened form of Bozorgmehr.
