Tansar

Tansar () was a Zoroastrian Herbadan Herbad (Chief judge) in late Parthian Empire And one of the supporters of Ardashir I. Tansar was apparently a Parthian aristocrat, but he turned to Neoplatonic beliefs. Then he joined Ardashir I and became Herbadan Herbad during his reign. He was commissioned to collect the Avesta and died on an unknown date. Tansar's great work is his letter to Goshnasb, which is one of the most important writings in the collection of Middle Persian literature, which provides valuable information about the social and administrative organization of Iran during the Sassanid period.
