Pyromancy (from Greek 'pyros', fire, and 'manteia', divination) is the art of divination by means of Greek society, virgins at the Temple of Athena in Athens regularly practiced pyromancy. It is also possible that followers of Hephaestus, the Greek god of fire and the forge, practiced pyromancy.
Types of Pyromancy
The most basic form of pyromancy is that in which the diviner observes flames, from a sacrificial fire, a candle, or another source of flame, and interprets the shapes that he or she sees within them. There are several variations on pyromancy, however, some of which are as follows:
Alomancy, divination by salt, one type of which involves casting salt into a fire
Botanomancy, divination by burning plants
Capnomancy, divination by smoke
Daphnomancy (also, Empyromancy), divination by burning laurel leaves
Causinomancy, divination by burning (non-specific as to the object burned)
