VishtaspaVishtaspa (𐬬𐬌𐬱𐬙𐬁𐬯𐬞𐬀 ; 𐎻𐏁𐎫𐎠𐎿𐎱 ; گشتاسپ ; Ὑστάσπης ) is the Avestan-language name of a figure of Zoroastrian scripture and tradition, portrayed as an early follower of Zoroaster, and his patron, and instrumental in the diffusion of the prophet's message. Although Vishtaspa is not epigraphically attested, he is – like Zoroaster – traditionally assumed to have been a historical figure, although obscured by accretions from legend and myth. In Zoroastrian tradition, which builds on allusions found in the Avesta, Vishtaspa is a righteous king who helped propagate and defend the faith.
Persian mythologyPersian mythology or Iranian mythology (Persian: اساطیرشناسی ایرانی) is the body of the myths originally told by ancient Persians and other Iranian peoples, and a genre of Ancient Persian folklore. These stories concern the origin and nature of the world, the lives and activities of deities, heroes, and mythological creatures, and the origins and significance of the ancient Persians' own cult and ritual practices.
KeyumarsKeyumars or Kiomars (کیومرث) was the name of the first king (shah) of the Pishdadian dynasty of Iran according to the Shahnameh. The name appears in Avestan in the form of 𐬔𐬀𐬌𐬌𐬊 𐬨𐬆𐬭𐬆𐬙𐬀𐬥 Gaiio Mərətan, or in medieval Zoroastrian texts as Gayōmard or Gayōmart. In the Avesta he is the mythological first human being in the world. The corresponding name in Middle Persian is 𐭪𐭣𐭬𐭫𐭲 Kayōmart. In Ferdowsi's Shahnameh he appears as the first shah of the world. He is also called the pišdād (پيشداد), the first to practice justice, the lawgiver.
AneranAnērān (Middle Persian, 𐭠𐭭𐭩𐭥𐭠𐭭) or Anīrân (Modern Persian, انیران) is an ethno-linguistic term that signifies "non-Iranian" or "non-Iran" (non-Aryan). Thus, in a general sense, 'Aniran' signifies lands where Iranian languages are not spoken. In a pejorative sense, it denotes "a political and religious enemy of Iran and Zoroastrianism." The term 'Aniran' derives from Middle Persian anērān, Pahlavi ʼnyrʼn, an antonym of ērān that in turn denoted either the people or the Sasanian Empire.
Avestan geographyAvestan geography refers to the investigation of place names in the Avesta and the attempt to connect them to real-world geographical sites. It is therefore different from the cosmogony expressed in the Avesta, where place names refer to mythical events or a cosmological order. Identifying such connections is important for localizing the people of the Avesta and is therefore crucial for understanding the early history of Zoroastrianism and the Iranian peoples.
