Porphyry, De antro nympharum 2: "For, as Eubulus says, Zoroaster was the first who consecrated in the neighbouring mountains of Persia, a spontaneously produced cave, florid, and having fountains, in honour of Mithra, the maker and father of all things; |12 a cave, according to Zoroaster, bearing a resemblance of the world, which was fabricated by Mithra. But the things contained in the cavern being arranged according to commensurate intervals, were symbols of the mundane elements and climates."
