Khwarrahbud
Khwarrahbud was a 4th-century Iranian scribe ("dabir") active during the reign of the Sasanian king (shah) Shapur II (). Attested in Armenian as "Khorōhbowt", Khwarrahbud was captured during Shapur II's wars against the Romans. During his stay in Roman territory, Khwarrahbud learned Greek and wrote a book on the accomplishments of Shapur II and Julian. Furthermore, Khwarrahbud also later translated into Greek a Persian book written by Rāstsakhwan (attested in Armenian as "Rastsohown"), one of his captive associates. The book was later used by the 6th-century historian Agathias.
