Tepegöz

Tepegöz is a one-eyed monster in the Book of Dede Korkut, a collection of Turkic epic tales. A. Guseynova says he was born to a shepherd and a peri, and Wikipedia says Basat killed him.

A. Guseynova, writing in 2010, says old tales of Turkic peoples, among them the Book of Dede Korkut, Gagauz stories and folklore from Siberia, Kazakhstan, Uzbekistan and Turkey, tell of Tepegöz (also Depegöz or Kellegöz) being born to a shepherd, a man of the earth, and a peri, a being from beyond it. She also claims that Iranian kings knew the story, and adds that Bozorgmehr, vizier to the Sasanian shah Anushirvan, had a book in Middle Persian whose title she gives as Ulu-khan ata bitigchi.

In V. V. Bartold's Russian translation, published in 1962, Aruz-Koja gets down from his horse and touches a heap with his spurs. The heap splits open and a boy steps out with a man's body and a single eye in his head. Aruz wraps him in the skirt of his coat and asks Bayundur Khan to give him the child, promising to raise him with his own son Bisat, and the khan agrees. At home a wet nurse puts the baby, whom the text calls Depe-Gez, to her breast. With his first pull he drains all her milk, with the second her blood, and with the third her soul.

Wikipedia calls Basat his half-brother and the only man able to kill him. Basat relies on his wits over his strength: he strikes Tepegöz in the eye, then cuts off his head with a magic sword, saving himself and his people. I. Z. Guseynov (2009) notes that G. Diez already argued the Tepegöz story is older than Homer's tale of Polyphemus, and that many scholars treat a hero's fight with a one-eyed giant as a standing motif of Eurasian epic. The writer Anar, in Azerbaijan International in 1998, described the story of Basat and Tapagoz as a fairy tale whose subject is a one-eyed monster, one of several genres mixed in the book.
