The traditional tales and stories of ancient Persia describe confrontations between good and evil, the victories of the gods, and the exploits of heroes and fabulous supernatural creatures. The Avesta is one of the primary sources for these stories. It describes the mother of all trees, the Saena, which stood within the Vourukasha Sea. In the Saena tree's branches lived a great falcon, the so-called great Saena bird (Pahlavi Senmurv). It sat on top of the tree and when it beat its wings it scattered the seeds, which were then carried away by the wind and the rain and distributed all over the earth.
