The Kamasutra is the oldest extant Indian scientific treatise on the subject of pleasure. It was written in the 3rd century CE by Vatsyayana Mallanaga. Concerning more than just the positions of sexual intercourse, the Kamasutra includes many other topics and has continued to be a significant cultural touchstone in India and the rest of the globe. Large portions of the Kamasutra are clearly written for men, yet the women in the Kamasutra speak in Sanskrit, and Vatsyayana argues at some length that some women, at least, should read this text, and that others should learn its contents in other ways (L3.1-14]. The correct answer is Kama Sutra . Key Points The Kama Sutra was written by the ancient Indian scholar Vatsyayana. He was a brahmin and lived in Pataliputra, India, in the second or third century CE (modern-day Patna in Bihar). He should not be mistaken for Pakilasvamin Vatsyayana. His name is occasionally mistakenly conflated with that o f Mallanaga, the Asuran seer who is credited with creating erotic science. Additional Information Arthashastra: Vishnugupta wrote Arthashastra. Vishnugupta ... Vatsayana Mallanaga is the author of KamaSutra . Note: Vatsayana Mallanaga was an author of ancient India who is mainly popularized only for Kamasutra so do not confuse Vatsayana with other ancient scholars or mathematicians who wrote a number of texts like Charaka or Bhaskaracharya.
