Agnivesha

Agnivesha is a legendary rishi in Hinduism, reputedly one of the earliest authors on Ayurveda. He is described to have codified the knowledge of his preceptor, Atreya, and arranged it in the form of a treatise, named the Charaka Samhita.

Legend

Agnivesha is described to be the chief pupil of Punarvasu Atreya. The Agnivesha Samhita, dated back to 1500 BCE, is based on Atreya's teachings, and is a lost text on Ayurveda. The Agniveśatantra, consisting of 12,000 verses, is stated to be the foundational text of the Agnivesha school, one of the six schools of early Ayurveda.
The text is mentioned in the Charaka Samhita: "the tantra as written by Agnivesha is compiled, edited and modified by Charaka"
