Crown or diadem. A tall felt hat often worn by the leader of a religious (Ṣúfí) order. On the first day of the Festival of Riḍván, Bahá'u'lláh set out from His home in Bag̲h̲dád for the Garden of Riḍván wearing a finely embroidered táj instead of His usual headgear. It was noted as a symbolic sign of His divine authority.
