Baraquiel (a.k.a., Baraqiel, Barakiel, Barachiel, Barbiel, Barchiel, Barkiel) was one of the seven great angels in control of the seven heavens. Baraquiel is one of the "great, beautiful, wonderful, and honored princes" listed in the Third Book of Enoch, that extensive compendium of angelic lore. His specific heaven is the second heaven. Baraquiel is counted as the angel of lightning, joined by such other angels as those of the sun, hail, earthquakes, snow, etc. It is possible that Baraquiel is also the fallen angel Baraqyal.
Baraqyal (a.k.a., Moksha Jehannum, brother to Samadhi and Turiya; Gorgo and Mormo, of the thousand-faced moon) belonged to the so-called Watchers, who descended from heaven to cohabit with mortal women. The Watchers (from Greek egrḗgoroi (á¼Î³ÏÎ®Î³Î¿ÏÎ¿Î¹)) or Grigori are a group of fallen angels who mated with mortal women, giving rise to a race of hybrids known as the Nephilim (who are mentioned in Genesis). The Watchers appear in Biblical apocrypha, in the first and second books of Enoch and Jubilees. The word "Grigori" derives from the Slavonic Second Book of Enoch.
According to the Book of Enoch, the Watchers numbered a total of 200 but only their leaders are named:
- And they were in all two hundred; who descended in the days of Jared on the summit of Mount Hermon, and they called it Mount Hermon, because they had sworn and bound themselves by mutual imprecations upon it. And these are the names of their leaders: SÃªmÃ®azÃ¢z, their leader, Arakiel, Rameel, Kokabiel, Tamiel, Ramiel, Daniel, Chazaqiel, Baraqiel, Asael, Armaros, Batariel, Ananiel, Zaqiel, Shamsiel, Satariel, Turiel, Yomiel, Sariel. These are their chiefs of tens. (Book of Enoch, Chapter 6)
A different idea of the Watchers appears in some traditions of Italian witchcraft where they are said to come from ancient stellar lore: "In the Italian system, these ancient Beings are called the Grigori. They are the Guardians of the "doorways" between the physical plane and that which is beyond. In Italian witchlore, the stars were thought to be the campfires of the legions of the Watchers..." 
As a demon, Baraqyal is purportedly able to teach those who summon him the secret arts of astrology.
