Zoroastrianism:
Zoroastrianism is considered an early influence on Judaism, Christianity
and Islam, and one of the first monotheistic religions. It emphasizes
that good and evil are separate entities at war with each other,
in the form of Ormuzd (the god of good, creation and truth) and
Ahriman (the god of evil destruction and lies), both ultimately
descended from the Wise Lord,
Ahura
Mazda. The holy book of Zoroastrianism is the Avesta,
which includes the hymns of Zoroaster (The Gathas, from which most
of his biographical information comes), liturgical texts and prayers.
Zoroastrianism is also sometimes called
Parsiism, after the Parsi community of India where it is practiced...
Zarathustra's story was fictionalized by Friedrich Nietzsche in
his 1885 book Also Sprach Zarathustra. The book, in turn, inspired
Richard Strauss's eerie 1896 composition of the same name, which
Stanley Kubrick used in the caveman sequence at the start of his
1968 film 2001: A Space Odyssey.
