Some design scholars believe the buta is the convergence of a stylized floral spray and a cypress tree: a Zoroastrian symbol of life and eternity. It is a bent cedar, and the cedar is the tree Zarathustra planted in paradise. The heavenly tree was “bent” under the weight of the Arab invasion and Muslim conquest of Persia. The "bent" cedar is also the sign of strength and resistance but modesty. The floral motif was originated in the Sassanid dynasty and later in the Safavid dynasty of Persia (1501–1736), and was a major textile pattern in Iran during the Qajar and Pahlavi dynasties. In these periods, the pattern was used to decorate royal regalia, crowns, and court garments, as well as textiles used by the general population.
