This was also the case with Heraclitus and his followers, who worshipped fire as the first cause; for this fire others named Hephæstus. The Persian Magi, too, and many of the inhabitants of Asia, worshipped fire; and besides them, the Macedonians, as Diogenes relates in the first book of his Persica. Why specify the Sauromatæ, who are said by Nymphodorus, in his Barbaric Customs, to pay sacred honours to fire? or the Persians, or the Medes, or the Magi? These, Dino tells us, sacrifice beneath the open sky, regarding fire and water as the only images of the gods.
