Aryana: Homeland of the Ancient Aryan Religion according to scripture
Aryana according to Eratosthnese
The Holy Aryan Empire - Acheamenid Persia
Monotheism's East to West Development
The word "Aryan" designates Indian and Iranian culture and "most justly" the latter where the term still lives on and is interchangeable with the linguistic, national, and religious identifier Iranian. The Aryans are recalled as the Airya in the ancient Iranian scriptures known as the Avesta, the oldest portions of which were composed by the ancient Aryan “poet-praiser” historians identify as ‘’Zarathushtra’’ (Gk. Zoroaster Ger. Zarathustra), and who were closely tied to speakers and clans or nations of Indo-Europe’s ancestral past including the Scythians, Sarmatians, and Cimmerians also included within the category of “Aryan.” Similarly the Aryans are recalled as the Arya in the ancient Indic scriptures known as the Vedas. The Avestan and Vedic Sanskrit languages of these respective Aryan speakers are almost identical and henceforth must trace back to a period shortly after the linguistic divergence of their hypothetical common ancestor known as Proto-Indo-Iranian. Scholars have dated these languages to a period ranging from 6000 BCE to no later than 1000 BCE. The homeland of the Aryans is recalled in the Avesta as Airyana Vaejah and roughly corresponds to the modern day territories of Afghanistan, Tajikistan, Georgia, Iran, Azerbaijan, Kurdistan, and Pakistan. Alternatively there is no record of an Aryan homeland in the Vedas although the place-name Arya-Varta which identifies the "abode of the Aryans" does appear in post-Vedic texts such as the Manusmirti, and indicates "the tract between the Himalaya and the Vindhya ranges, from the Eastern Sea to the Western Sea." The Aryan religion of the Avesta, also known as the "Magical or Ethical Religion," demonstrates elements of monotheism sometimes referred to as "monotheistic dualism" which contributed to the core of the Abrahamic belief system. Similarly there are traces of monotheism in the Vedas, but evidence of polytheism appears already in the most ancient of the Vedic compositions, the Rig Veda. The religion of the Vedic Aryans, also known as ancient Hinduism, in its refined form, developed into Buddhist philosophy. In addition to having made contributions to the Abrahamic faiths, the religion of the Avestic Aryans also made significant contributions to several other movements throughout the course of history including Greek philosophy  the Mithraic Mysteries of the pre-Christian Roman Empire  both Shiaism and Sufism, the Renaissance Europe's Volk movement, and Freemasonry (eg. the Sarastro Lodge named after Zarathushtra himself). In specific the Aryan religion of the Avestan people has also had a significant influence on a handful of individuals in modern day times including Friedrich Nietzsche (eg. Thus Spoke Zarathustra), Richard Strauss (eg. Also Spoke Zarathustra), Mozart (eg. The Magic Flute), Thomas Edison (inventor of the Mazda Bulb), President Truman (quoted for his reference to the Persian Emperor of Aryan lineage: “I am Cyrus”), Stanley Kubrick (having incorporated Strauss’s Also Spoke Zarathustra into the beginning score of his 2001: A Space Odyssey). In their orthodox forms the religion of the Avestic and Vedic Aryans live on, respectively, with the Zartushtis or Parsis of Irano-Afghanistan and India, and the Hindus of South Asia, many of whom have also taken up residence in Europe and the United States.
Proto-Indo-Iranian religion or Proto-Iranic religion: The various beliefs and practices from which the later indigenous religion of the Iranian peoples evolved. This religion also influenced the development of the Indian religions.
Zoroastrianism: The present-day umbrella term for the indigenous native beliefs and practices of the Iranian peoples. While present-day Zoroastrianism is monolithitic, a continuation of the elite form of Sassanid times, in antiquity it had several variants or denominations, differing slightly by location, ethnic affiliation and historical period. It once had large population and high diversity.
Mandaeism: A gnostic monotheism of (at the latest) the 1st century CE observed Mandā d-Heyyi - "Knowledge of Life". Mandaean theology is based more on a common heritage than on any set of religious creeds and doctrines.
Manichaeism: 3rd century ditheistic gnosticism that may have been influenced by Mandaeism. Manichaens believed in a "Father of Greatness" (Aramaic: Abbā dəRabbūṯā, Persian: pīd ī wuzurgīh) and observed Him to be the highest deity (of light).
The early Islamic period saw the development of Persian mysticism, a traditional interpretation of existence, life and love with Perso-Islamic Sufi monotheism as its practical aspect. This development believed in a direct perception of spiritual truth (God), through mystic practices based on divine love.
Khurramites, a 9th-century religious and political movement based on the 8th century teachings of Sunpadh, who preached a syncretism of Shia Islam and Zoroastrianism. Under Babak Khorramdin, the movement sought the redistribution of private wealth and the abolition of Islam.
Behafaridians, an 8th-century cult movement around the prophet Behafarid. Although the movement is considered to have its roots in Zoroastrianism, Behafarid and his followers were executed on charges (made by Zoroastrians) of harm to both Zoroastrianism and Islam.
Yarsan, a religious order of Yazdanism, which is believed to have been founded in the 16th century. Yazdanism promulgated the belief in a God manifest as one primary and five secondary avatars to form with God the Holy Seven.
^J.P. Mallory | 1989 | p=125-126 "As an ethnic designation, the word is most properly limited to the Indo-Iranians, and most justly to the latter where it still gives its name to the country Iran (from the Avestan genitive plural airyanam through later Iranian eran to iran)."
^Albert De Jong |1997 |p= 320 “The only reliable tradition that can be found is the passage, possibly from Hecataeus of Abdera, in Diodorus Siculus 1.94.2, which connects Zathraustes with the Ariani. This mirrors the Avestan (and later Zoroastrian) idea of Zarathustra living in Airyana Vaejah and proclaiming his message to “the Aryans.”

The result was a mixture of forms from different parts of eastern Greece. The result was a mixture of forms from different dialects and from different chronological stages. Each poet drew on a repertory of inherited and memorized formulaic poetic language, but in composing the epics in performance would inject newer material of his own devising. Bards constantly adapted the poetic language, and to make the verses scan they would sometimes create forms that from a historical point of view are wrong.” Cite error: Invalid <ref> tag; name "Indo-European_Language_and_Culture" defined multiple times with different content (see the help page).
