Krishna-Dwaipayana Vyasa

Krishna Dvaipāyana Vyāsa, also known as Vyāsa or Veda-Vyāsa (वेदव्यास, the one who classified the Vedas into four parts) is a central and revered figure in most Hindu traditions. He is traditonally regarded as the author of the Mahābhārata, although it is also widely held that he only composed the core of the epic, the Bhārata. A significant portion of the epic later was only added in later centuries, which then came to be known as the Mahābhārata. The date of composition of this epic is not known - It was definitvely part of the traditions in Indian subcontinent at the time Gautam Buddha (~500 BCE) which would suggest it having been already around for atleast a few centuries. It was chiefy put down in the written form only somewhere between 300 BCE to 300 CE.

As the name would suggest, Vyāsa is believed to have categorised the primordial single Veda into its four canonical collections. He is also considered to be the scribe of Purānās, ancient Hindu texts eulogizing various deities, primarily the divine Trimurti God in Hinduism through divine stories.
