The Cypress of Kashmar is a mythical cypress tree of legendary beauty and gargantuan dimensions. It is said to have sprung from a branch brought by Zoroaster from Paradise and to have stood in today's Kashmar in northeastern Iran and to have been planted by Zoroaster in honor of the conversion of King Vishtaspa to Zoroastrianism. According to the Iranian physicist and historian Zakariya al-Qazwini King Vishtaspa had been a patron of Zoroaster who planted the tree himself. In his "ʿAjā'ib al-makhlūqāt wa gharā'ib al-mawjūdāt", he further describes how the Al-Mutawakkil in 247 AH (861 AD) caused the mighty cypress to be felled, and then transported it across Iran, to be used for beams in his new palace at Samarra. Before, he wanted the tree to be reconstructed before his eyes. This was done in spite of protests by the Iranians, who offered a very great sum of money to save the tree. Al-Mutawakkil never saw the cypress, because he was murdered by a Turkish soldier (possibly in the employ of his son) on the night when it arrived on the banks of the Tigris.
