Zarathustra
A historic personality whose life became “enshrowded in legend. He lived not later than the 6th century B.C. in ancient Persia (Iran or Bactria) and is credited with establishing a dualism called after him Zoroastrianism (q.v.). In Also sprach Zarathustra, Nietzsche makes him, though dissociated from his doctrines, the bearer of his message. — K.F.L.
