Zoroastrianism or Mazdayasna is one of the world's oldest continuously practiced religions, based on the teachings of the Iranian-speaking prophet Zoroaster (also known as "Zaraθuštra" in Avestan or "Zarthost" in Modern Persian). Zoroastrianism has a dualistic cosmology of good and evil and an eschatology, predicting the ultimate conquest of evil. Zoroastrianism exalts an uncreated and benevolent deity of wisdom, Ahura Mazda ("Wise Lord"), as its supreme being. The unique historical features of Zoroastrianism, such as its monotheism, messianism, judgment after death, heaven and hell, and free will may have influenced other religious and philosophical systems, including Second Temple Judaism, Gnosticism, Greek philosophy, Christianity, Islam, the Baháʼí Faith, and Buddhism.
