Tur (mythology) Tur (Tur – son of Fereydun) (Persian: تور‎ ‎ ) is a character in the Persian epic Shahnameh. He is the second son of the legendary Iranian king Fereydun and brother of both Salm and Iraj. His name, meaning "brave", was given to him by his father when the young prince bravely fights the dragon that had attacked him and his brothers. When Fereydun divides his empire among his sons, he gives Turkistan and China to his second son Tur. This is the beginning of the nation of Turan, the neighbor and rival of the Iranians. Some of the most important characters of Shahnameh, such as Afrasiab, are his descendants. He was killed by Manuchehr.
