Zoroaster in the context of "Zoroastrianism"

Friedrich Wilhelm Nietzsche (15 October 1844 – 25 August 1900) was a German philosopher. He began his career as a classical philologist, turning to philosophy early in his academic career. In 1869, aged 24, Nietzsche became the youngest professor to hold the Chair of Classical Philology at the University of Basel. Plagued by health problems for most of his life, he resigned from the university in 1879, and in the following decade he completed much of his core writing. In 1889, aged 44, he suffered a collapse and thereafter a complete loss of his mental faculties, with paralysis and vascular dementia, living his remaining 11 years under the care of his family until his death. His works and his philosophy have fostered not only extensive scholarship but also much popular interest.

Nietzsche's work encompasses philosophical polemics, poetry, cultural criticism and fiction, while displaying a fondness for aphorisms and irony. Prominent elements of his philosophy include his radical critique of truth in favour of perspectivism; a genealogical critique of religion and Christian morality and a related theory of master–slave morality; the aesthetic affirmation of life in response to both the "death of God" and the profound crisis of nihilism; the notion of Apollonian and Dionysian forces; and a characterisation of the human subject as the expression of competing wills, collectively understood as the will to power. He also developed influential concepts such as the Übermensch and his doctrine of eternal return. In his later work he became increasingly preoccupied with the creative powers of the individual to overcome cultural and moral mores in pursuit of new values and aesthetic health. His body of work touched a wide range of topics, including art, philology, history, music, religion, tragedy, culture and science, and drew inspiration from Hebrew literature, Indian literature and Greek tragedy, as well as figures such as Zoroaster, Arthur Schopenhauer, Ralph Waldo Emerson, Richard Wagner, Fyodor Dostoevsky and Johann Wolfgang von Goethe.

The Gathas (/ˈɡɑːtəz, -tɑːz/) are five hymns in the Avestan language from the Zoroastrian oral tradition of the Avesta. The oldest surviving text fragment dates from 1323 CE, but they are believed by scholars to have been composed before 1000 BCE and passed down orally for centuries. They are traditionally believed to have been composed by the prophet Zarathushtra (Zoroaster) himself. They form the core of the Zoroastrian liturgy (the Yasna). They are arranged in five different modes or metres.

The Avestan term gāθā (𐬔𐬁𐬚𐬁 "hymn", but also "mode, metre") is cognate with Sanskrit gāthā (गाथा), both from the Proto-Indo-Iranian word *gaHtʰáH, from the root *gaH- "to sing".

Ancient Iranian religions were a set of ancient beliefs and practices of the Iranian peoples before the rise of Zoroastrianism. The religion closest to it was the historical Vedic religion that was practiced during the Vedic period. The major deities worshipped were Ahura Mazda and Mithra from Iran to Rome, but Atar was also worshipped, as names of kings and common public showing devotion to these three exist in most cases. But some sects, the precursors of the Magi, also worshipped Ahura Mazda, the chief of the Ahuras. With the rise of Zoroaster and his new, reformatory religion, Ahura Mazda became the principal deity, while the Daevas were relegated to the background. Many of the attributes and commandments of Varuna, called Fahrana in Median times, were later attributed to Ahura Mazda by Zoroaster.

The Iranian peoples emerged as a separate branch of the Indo-Iranians in the 2nd millennium BC, during which they came to dominate the Eurasian Steppe and the Persian Plateau. Their religion is derived from Iranian religions, and therefore shares many similarities with the Vedic religion of India. Although the Persian peoples left little written or material evidence of their religious practices, their religion is possible to reconstruct from scant Iranian, Babylonian and Greek accounts, similarities with Vedic and other Indo-European religions, and material evidence.

The Avestan period (c. 1500 – c. 400 BCE) is the period of Iranian history when the collection of canonical texts of Zoroastrianism called the Avesta was produced. The period saw important developments to religious thought and to Persian mythology and the tradition of epic poetry exemplified by the Shahnameh.

Scholars can reliably distinguish between two different linguistic strata in the Avesta labeled "Old Avestan" and "Young Avestan". These two strata represent two different stages in the development of the Avestan language and the society of its speakers. The Old Avestan society is the one to which Zoroaster and his immediate followers belonged. The Young Avestan society is less clearly delineated and reflects a longer time span.

Manichaeism (/ˌmænɪˈkiːɪzəm/; in Persian: آئین مانی, romanized: Āʾīn-i Mānī; Chinese: 摩尼教; pinyin: Móníjiào) was a major world religion founded in the third century CE by the Parthian Iranian prophet Mani (C.E. 216–274) in the Sasanian Empire. Variably described as a Christian heresy and a Gnostic movement, Manichaeism was an organized and doctrinal religious tradition in its own right. It taught an elaborate dualistic cosmology describing the struggle between a good spiritual world of light, and an evil material world of darkness. Through an ongoing process that takes place in human history, light is gradually removed from the world of matter and returned to the world of the divine.

Mani's teachings were intended to integrate, succeed, and surpass the "partial truths" of various prior faiths and belief systems, including Platonism, Christianity, Zoroastrianism, Buddhism, Marcionism, Hellenistic and Rabbinic Judaism, Gnostic movements, Ancient Greek religion, Babylonian and other Mesopotamian religions, and mystery cults. Some forms of Manichaeism see Mani as the final prophet after Zoroaster, the Buddha, and Jesus. The Manichaean scriptural canon includes seven works attributed to Mani, written originally in Syriac. Manichaean sacramental rites included prayers, almsgiving, and fasting. Communal life centered on confession and the singing of hymns.

Georgios Gemistos Plethon (Greek: Γεώργιος Γεμιστὸς Πλήθων; Latin: Georgius Gemistus Pletho c. 1355/1360 – 1452/1454), commonly known as Gemistos Plethon, was a Greek scholar and one of the most renowned philosophers of the Late Byzantine era. He was a chief pioneer of the revival of Greek scholarship in Western Europe. As revealed in his last literary work, the Nomoi or Book of Laws, which he circulated only among close friends, he rejected Christianity in favour of a return to the worship of the classical Hellenic gods, mixed with ancient wisdom based on Zoroaster and the Magi.

In 1438–1439 he reintroduced Plato's ideas to Western Europe during the Council of Florence, in a failed attempt to reconcile the East–West schism. Plethon also formulated his political vision in several speeches throughout his life. The boast in one of the speeches that "We are Hellenes by race and culture" and his proposal of a reborn Byzantine Empire following a utopian Hellenic system of government centered in Mystras, have generated discussion about Byzantine and modern Greek identity. In this regard, Plethon has been labelled both "the last Hellene" and "the first modern Greek".
