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".
AshaAsha (ˈʌʃə) or arta (ˈɑrtə; 𐬀𐬴𐬀 Aṣ̌aArta) is a Zoroastrian concept with a complex and highly nuanced range of meaning. It is commonly summarized in accord with its contextual implications of 'truth' and 'right' (or 'righteousness'), 'order' and 'right working'. For other connotations, see Meaning below. It is of cardinal importance to Zoroastrian theology and doctrine. In the moral sphere, aṣ̌a/arta represents what has been called "the decisive confessional concept of Zoroastrianism".
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.
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.
SistanSistān (سیستان), also known as Sakastān (سَكاستان "the land of the Saka") and Sijistan, is a historical and geographical region in present-day south-eastern Iran, south-western Afghanistan and north-western Pakistan. Largely desert, the region is bisected by the Helmand River, the largest river in Afghanistan, which empties into the Hamun Lake that forms part of the border between Iran and Afghanistan. Sistan derives its name from Sakastan ("the land of the Saka").
TuranTuran (Tūiriiānəm, Tūrān; Turân, thuːˈɾɒːn, "The Land of Tur") is a historical region in Central Asia. The term is of Iranian origin and may refer to a particular prehistoric human settlement, a historic geographical region, or a culture. The original Turanians were an Iranian tribe of the Avestan age. In ancient Iranian mythology, Tūr or Turaj (Tuzh in Middle Persian) is the son of the emperor Fereydun. According to the account in the Shahnameh, the nomadic tribes who inhabited these lands were ruled by Tūr.
AshiAshi (Avestan: 𐬀𐬴𐬌 aṣ̌i/arti) is the Avestan language word for the Zoroastrian concept of "that which is attained." As the hypostasis of "reward," "recompense," or "capricious luck," Ashi is also a divinity in the Zoroastrian hierarchy of yazatas. Avestan 'ashi' is a feminine abstract noun, deriving from the root ar-, "to allot," with a substantivizing -ta suffix, hence aṣ̌i/arti "that which is granted." In the Avesta, the term implies both material and spiritual recompense.
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.
Middle Persian literatureMiddle Persian literature is the corpus of written works composed in Middle Persian, that is, the Middle Iranian dialect of Persia proper, the region in the south-western corner of the Iranian plateau. Middle Persian was the prestige dialect during the era of Sassanid dynasty. The rulers of the Sassanid Empire (224–654 CE) were natives of that south-western region, and through their political and cultural influence, Middle Persian became a prestige dialect and thus also came to be used by non-Persian Iranians.
