Sasanian EmpireThe Sasanian Empire (səˈsɑːniən,_səˈseɪniən), officially known as Eranshahr ("Land/Empire of the Iranians"), was the last Iranian empire before the early Muslim conquests of the 7th–8th centuries AD. Named after the House of Sasan, it endured for over four centuries, from 224 to 651 AD, making it the longest-lived Persian imperial dynasty. The Sasanian Empire succeeded the Parthian Empire, and re-established the Persians as a major power in late antiquity alongside its neighbouring arch-rival, the Roman Empire (after 395 the Byzantine Empire).
Kayanian dynastyThe Kayanians (Persian: دودمان کیانیان; also Kays, Kayanids, Kaianids, Kayani, or Kiani) are a legendary dynasty of Persian/Iranian tradition and folklore which supposedly ruled after the Pishdadians. Considered collectively, the Kayanian kings are the heroes of the Avesta, the sacred texts of Zoroastrianism, and of the Shahnameh, the national epic of Greater Iran. As an epithet of kings and the reason the dynasty is so called, Middle 𐭪𐭣 and New Persian kay(an) originates from Avestan 𐬐𐬀𐬎𐬎𐬌 kavi (or kauui) "king" and also "poet-sacrificer" or "poet-priest".
ZurvanismZurvanism is a fatalistic religious movement of Zoroastrianism in which the divinity Zurvan is a first principle (primordial creator deity) who engendered equal-but-opposite twins, Ahura Mazda and Angra Mainyu. Zurvanism is also known as "Zurvanite Zoroastrianism", and may be contrasted with Mazdaism. In Zurvanism, Zurvan was perceived as the god of infinite time and space and was aka ("one", "alone"). Zurvan was portrayed as a transcendental and neutral god, without passion, and one for whom there was no distinction between good and evil.
DenkardThe Dēnkard or Dēnkart (Middle Persian: 𐭣𐭩𐭭𐭪𐭠𐭫𐭲 "Acts of Religion") is a 10th-century compendium of Zoroastrian beliefs and customs during the time. The Denkard is to a great extent considered an "Encyclopedia of Mazdaism" and is a valuable source of information on the religion especially during its Middle Persian iteration. The Denkard is not considered a sacred text by a majority of Zoroastrians, but is still considered worthy of study.
BundahishnBundahishn (Middle Persian: , "Primal Creation") is the name traditionally given to an encyclopedic collection of Zoroastrian cosmogony and cosmology written in Book Pahlavi. The original name of the work is not known. Although the Bundahishn draws on the Avesta and develops ideas alluded to in those texts, it is not itself scripture. The content reflects Zoroastrian scripture, which, in turn, reflects both ancient Zoroastrian and pre-Zoroastrian beliefs.
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.
AvestaThe Avesta (ə'vɛstə) is the primary collection of religious texts of Zoroastrianism, composed in the Avestan language. The Avesta texts fall into several different categories, arranged either by dialect, or by usage. The principal text in the liturgical group is the Yasna, which takes its name from the Yasna ceremony, Zoroastrianism's primary act of worship, and at which the Yasna text is recited. The most important portion of the Yasna texts are the five Gathas, consisting of seventeen hymns attributed to Zoroaster himself.
ZoroasterZoroaster, also known as Zarathustra, is regarded as the spiritual founder of Zoroastrianism. He is said to have been an Iranian prophet who founded a religious movement that challenged the existing traditions of ancient Iranian religion, and inaugurated a movement that eventually became a staple religion in ancient Iran. He was a native speaker of Avestan and lived in the eastern part of the Iranian plateau, but his exact birthplace is uncertain.
