This image is taken from the 23rd image in a series of drawings from the seventeenth century alchemical work attributed to Eugenius Philalethes, the Speculum Veritatis (Mirror of Truth.) This simple symbol of a fire triangle with three radiating arrows below represents the “Perfect Red King,” the Sulfur of the Philosophers.
In alchemy, sulphur represents Sol, the fiery male element (the counterpart of Luna, mercury, the female element) of the Celestial marriage (conjunctio). Chemically, the red sulfur was a mixture of mercury (spirit) and sulfur (soul), the marriage of which also represented the spiritual goal of alchemical work. This emblem appears in the Constantine, the movie adaptation of the Hellblazer Comic Book series, as a tattoo worn as a protective device by the title character, used to summon the angel Gabriel.
