Gayomart

Keyumars (Persian: کیومرث‎‎) is the Persian form of the name Gayō Marətan (appearing in medieval Zoroastrian texts as Gayōmard or Gayōmart), the Avestan name of the mythological first human being in the world. The corresponding name in Middle Persian is Kayōmart.

In Ferdowsi's Shahnameh he appears as the first shah of the world. He is also called the pishdād (پيشداد), the first to practice justice, the lawgiver.

The Avestan form means "the living mortal", from gaya "life" and marətan "mortal, human being"; cf. Persian mard "human" (Persian: مَرد‎‎).

Keyumars is also a popular first name in contemporary Iran.

According to the Zoroastrian creation myth, Gayōmart was the first human, or, according to the Avesta, he was the first person to worship Ahura Mazda. The Avestan forms Mashya and Mashyana appear as the male and female first humans; their names are versions of the word marətan "mortal".

In the eighth book of the Denkard, a reference is made to the Chethrdāt section of the Avesta, which is divided into 21 sections. Apparently this section dealt with how the world and mankind were created, including the creation of Gayōmart. References are also made to the Varshtmānsar section, which also included information about Gayōmart which Ahura Mazda had given to Zoroaster: "For 30 centuries I kept the world from corruption and decay, when the 30th century came to an end the Dīvs assaulted Gayōmart ... But I finally repelled them and plunged them into the darkness".
