[1] The festival is recorded by many authors including Biruni, Gardizi, Asadi Tusi, Anwari etc.
According to Biruni and Gardizi, in Khorasan, an assortment of meat and all sorts of grain, vegetables, and fruits were cooked together in a pot called dīg-e Bahmanjana (the pot of Bahmanagān).
According to Gardizi, the flowers of the plant named the red-Bahman (Persian: Bahman-e Sorkh) were mixed with fresh milk.
He further continues that the people believed it to be beneficial for the memory as well to keep away the evil eye.
This plant is the same as the equivalent modern Persian term zardak-e ṣaḥrāʾī (a wild carrot), which blooms in the month of Bahman (January–February).
