Tahmuras

He invented the spinning and weaving of wool, learned to domesticate chickens, how to store up fodder for livestock instead of merely grazing them, and how to train animals like dogs and falcons to hunt for people.

Georges Dumézil provides a summary of a bawdy and scatological, but nonetheless instructive account of the death of Taxmoruw (Tahmures) preserved in a Parsi revayat translated by Danish orientalist and historian Arthur Christensen and published by Friedrich von Spiegel.

Meanwhile, Jamshid, Taxmoruw's devoted brother (not son, as in the Shahnameh), scours the world in search of his body until eventually he learns from Srosh, the well-nigh omniscient confidant of Ahura Mazda, that it is hidden in Ahriman's bowels.

The excited Ahriman agrees readily to the bargain and bends over, presenting his anus, whereupon Jamshid plunges his hand up the demon's rectum, deep into his belly, quickly pulls out his brother's corpse, places it on the ground and flees.

Thankful that he has at last been able to give his brother a fitting funeral, Jamshid can finally take time to glance at the hand which has been up Ahriman's anus and sees, to his horror, that it is pale and stinking, starting to waste away with a foul disease similar to leprosy.

Thus comes about the discovery of gōmēz - cow urine, considered as the purificatory liquid par excellence in Zoroastrianism and used as such in the nine-night ritual of Barashnûm, (as detailed in the ninth chapter of the Vendidad).

[2] According to verses 8–9 of the eighteenth chapter of the cosmological treatise known as the Bundahishn, the three preeminent Atar (Great Fires) of ancient Iran—Farnbag, Gushnasp and Burzin Mihr—were brought thither on the back of the ox Srishok from a place named Khwaniratha, during the reign of the primordial ruler Takhmurup—presumably with his knowledge and possibly at his command.

[3][4] The unusual concept of fire burning in the midst of water is found also in relation to the ancient Indo-Iranian deity Apam Napat and both occurrences of the mythological motif may owe something to early observation of flames (derived from the welling up of natural hydrocarbons) hovering near the surface of the Caspian Sea—more specifically the Southwestern part, exploited currently by the Absheron gas field near Baku in Azerbaijan.
