In a 2014 flyer for teachers by Science Foundation Ireland Education and Public Engagement for primary schools’ science week competition, it’s noted that “bag-pipes were invented in Persia, not Scotland”…

According to Rirchard Noll’s 1994 book on Swiss psychotherapist Dr. Carl Jung, “around 1900 a ‘Cult of Mazdaznan’ was founded in the United States by a German immigrant from Poznan, Otto Hanisch (1854-1936).  Hanisch, who used an Iranian-sounding alias (Ottoman Zar-Adusht Ha’nish), alleged that he was born in Tehran and that his cult was remnant of the Zoroastrianism of ancient Iran….  By 1910 the cult had spread to Europe…”

The following is from a 1901 book by English historian and translator George Mead on a well-known 1st c. philosopher and reformist Apollonius of Tyana, who was of Greek heritage in Roman-controlled Cappadocia, Asia Minor (note the word “Cappadocia” is Iranian in origin given Iranians, Anatolians, Armenians, and Greeks lived in that region for thousands of years prior to the arrival of the Romans):

“And even if we cannot go so far as to entertain the possibility of direct personal contact, there has to be taken into consideration the fact that Pherecydes, the master of Pythagoras, may have been acquainted with some of the main ideas of Vaidic lore.  Pherecydes taught at Ephesus, but was himself most probably a Persian, and it is quite credible that a learned Asiatic, teaching a mystic philosophy and basing his doctrine upon the idea of rebirth, may have had some indirect, if not direct, knowledge of Indo-Aryan thought.”

~ Indo-Aryans refer to sister culture Vedic Sanskrit to Avestan-Aryans or Iranians… the separation of the Indo-Iranians may have been around 1800 BCE…

In noting an Iranian term is used for bow and quiver in the Greek language and the Achaean culture with ties to the Mycenaeans has Indo-Iranian attribution, Elena Kuz’mina writes in her 2007 book on the Indo-Iranians that:

“In Greek myth Apollo, the Sun god, was born in the north, in the Ripa mountains.  In the vernal equinox [Spring equinox or March 20 = Zoroastrian Iranian New Year] white swans harnessed to a chariot carry him to Greece….  Ripa is the name of the Ural mountains, which are situated according to Indo-Iranian mythology in their homeland….  In the Urals, on the vernal equinox, there is a mass swan migration….  These facts support the existence of the areal Greek-Indo-Iranian contacts and the corresponding localization of the homeland in the steppes, to be more exact, in the Urals.”
