Fire is one of the four classical elements along with earth, water and air in ancient Greek philosophy and science.
In one Greek myth, Prometheus stole fire from the gods to protect the otherwise helpless humans, but was punished for this charity.
He described how fire gave rise to the other elements as the: "upward-downward path", (ὁδὸς ἄνω κάτω),[3] a "hidden harmony" [4] or series of transformations he called the "turnings of fire", (πυρὸς τροπαὶ),[5] first into sea, and half that sea into earth, and half that earth into rarefied air.
[7] He was known as the "weeping philosopher" and died of hydropsy, a swelling due to abnormal accumulation of fluid beneath the skin.
In the Timaeus, Plato's major cosmological dialogue, the Platonic solid he associated with fire was the tetrahedron which is formed from four triangles and contains the least volume with the greatest surface area.
[9] According to Aristotle, the four elements rise or fall toward their natural place in concentric layers surrounding the center of the Earth and form the terrestrial or sublunary spheres.
Other things associated with fire and yellow bile in ancient and medieval medicine included the season of summer, since it increased the qualities of heat and aridity; the choleric temperament (of a person dominated by the yellow bile humour); the masculine; and the eastern point of the compass.
In alchemic tradition, metals are incubated by fire in the womb of the Earth and alchemists only accelerate their development.
In Indian tradition fire is also linked to Surya or the Sun and Mangala or Mars, and with the south-east direction.
As an element, fire has mixed symbolism because it represents energy, which can be helpful when controlled, but volatile if left unchecked.
Freemasonry takes the ancient symbolic meaning of fire and recognizes its double nature: creation, light, on the one hand, and destruction and purification, on the other.
