Zoroastrianism was founded by Zarathushtra sometime between 2000 and 600 B.C. in Persia, which is now modern day Iran. They believe in a single god, Ahura Mazda, who is a supreme being and communicates with humans by a number of attributes, called Amesha Spentas or Bounteous Immortals. The Zoroastrian holy book is termed the Avesta, which includes the original words of the founder Zarathushtra preserved in a series of five hymns, called the Gathas. The Afrinagan ceremony is a multi-part service that is central to Zoroastrian public ceremonies. The photomicrograph above depicts a flower stem, representing the flowers that are heavily used in the Afrinagan service.
