When the Peries are unable to withstand their foes, they solicit the aid of some mortal hero. Enchanted arms and talismans enable him to cope with the gigantic Deevs, and he is conveyed to Jinnestân on the back of some strange and wonderful animal. His adventures in that country usually furnish a wide field for poetry and romance to expatiate in. The most celebrated adventurer in Jinnestân was Tahmuras, surnamed Deev-bend (_Deev-binder_),[30] one of the ancient kings of Persia. The Peries sent him a splendid embassy, and the Deevs, who dreaded him, despatched another. Tahmuras, in doubt how to act, consults the wonderful bird Seemurgh,[31] who speaks all languages, and whose knowledge embraces futurity. She advises him to aid the Peries, warns him of the dangers he has to encounter, and discloses his proper line of action. She further offers to convey him to Jinnestân, and plucks some feathers from her breast, with which the Persian monarch adorns his helmet. Mounted on the Seemurgh, and bracing on his arm the potent buckler of Jân-ibn-Jân,[32] Tahmuras crosses the abyss impassable to unaided mortality. The vizier Imlân, who had headed the Deev embassy, deserting his original friends, had gone over to Tahmuras, and through the magic arts of the Deev, and his own daring valour, the Persian hero defeats the Deev-king Arzshenk. He next vanquishes a Deev still more fierce, named Demrush, who dwelt in a gloomy cavern, surrounded by piles of wealth plundered from the neighbouring realms of Persia and India. Here Tahmuras finds a fair captive, the Peri Merjân,[33] whom Demrush had carried off, and whom her brothers, Dâl Peri and Milân Shâh Peri, had long sought in vain. He chains the Deev in the centre of the mountain, and at the suit of Merjân hastens to attack another powerful Deev named Houndkonz; but here, alas! fortune deserts him, and, maugre his talismans and enchanted arms, the gallant Tahmuras falls beneath his foe.
