In demonology Bifrons was a demon, Earl of Hell, with six legions of demons (twenty-six for other authors) under his command. He teaches sciences and arts, the virtues of the gems and woods, herbs, and changes corpses from their original grave into other places, sometimes putting magic lights on the graves that seem candles. He appears as a monster, but then changes his shape into that of a man.

The origin of the name is, without any doubt, the Roman god Bifrons (Janus).

Other spellings: Bifrovs, Bifröus.

Bifrons was also one the names given to the baphomet allegedly worshipped by the Knights Templar, and which description was as a statue with two heads surely inspired in the Roman god Bifrons, one looking towards the left to tell the past, and the other looking towards the right to tell the future, all this by means of the power of a demon (there were other suppositions on the figure of the baphomet).
