Garga Muni

One of the greatest sages of the Puranic times. Garga was the son of Rishi Bharadwaja and Susheela.He was better known as Garga Muni. He was the family priest of the family of Nanda (the foster-father of Krishna).

He named Krishna as "Krishna" after receiving the name by meditation. From the Vishnu Purana and other Puranas, one understands that although basically of Kshatriya origin, a branch of Gargas became Brahmins and migrated westwards and joined the Yavanas (Ionians).

This could be the possible reason that later day Indians referred to Greek mathematicians and astronomers as Gargacharyas while they also maintained that a Vridha-Garga (Earlier or Older Garga) was the pioneer in astronomy.
