Bhrigu (Sk.). One of the great Vedic Rishis. He is called “Son” by Manu, who confides to him his Institutes. He is one of the Seven Prajâpatis or progenitors of mankind, which is equivalent to identifying him with one of the creative gods, placed by the Purânas in Krita Yug, or the first age, that of purity. Dr. Wynn Westcott reminds us of the fact that the late and very erudite Dr. Kenealy (who spelt the name Brighoo), made of this Muni (Saint) the fourth, out of his twelve, “divine messengers” to the World, adding that he appeared in Tibet, A.N. 4800 and that his religion spread to Britain, where his followers raised the megalithic temple of Stonehenge. This, of course, is a hypothesis, based merely on Dr. Kenealy’s personal speculations.
