3218–3078 BCE. (Sin, “spirit”; nong, “farming.”) Often romanized from Chinese as Shen Nong. In China, he is known as the second mythical emperor, but he was in fact a lord in ancient Korea’s Baedal dynasty (3898–2333 BCE). He was called Sin-nong because of his contribution to the development of agriculture. He is also renowned as the father of Eastern medicine.
