In demonology, Beleth also spelled Bilet, Bileth, Byleth and Bilith is a mighty and terrible king of Hell, who has eighty-five legions of demons under his command. He rides a pale horse, and all kinds of music is heard before him, according to most authors on demonology and the most known grimoires. According to Pseudomonarchia Daemonum Ham, Noah's son, was the first in invoking him after the flood, and wrote a book on Mathematics with his help.
When appearing he looks very fierce to frighten the conjurer or to see if he is courageous. The conjurer must be brave, and holding a hazel wand in his hand must draw a triangle by striking towards the South, East, and upwards, then commanding Beleth into it by means of some conjurations.
If he does not obey, the conjurer must rehearse all threatens the conjurations said and then Beleth will obey and do all that he is commanded. But the conjurer must be respectful and do homage unto Beleth due to his rank, and hold a silver ring in the middle finger of the left hand against his face, as it is the use of hellish kings and princes before Amaymon.
In Tolkien's legendarium, the House of Bëor (pronounced [ˈbɛɔr]) were the family of Men who ruled over the eldest of the Three Houses of the Edain that had allied with the Elves in the First Age.
The First House of Men, called the House or Folk of Bëor, was the smallest of the Three, having at the time of their coming to Beleriand "no more than two thousand full-grown men; and they were poor and ill-equipped, but they were inured to hardship and toilsome journeys carrying great loads, for they had no beasts of burden." Most of the Folk of Bëor had brown hair with grey eyes, and some of them were swarthy in skin. They were taller than the Folk of Haleth, but still less in height than the House of Hador. The Bëorians were "steadfast in endurance of hardship and sorrow, slow to tears and to laughter; their fortitude needed no hope to sustain it." They were akin to the Folk of Hador and spoke a closely related language, though its knowledge was mostly lost later.
