Ananga Ranga

The book "Ananga Ranga" (Stage of Love) was written by Kalyana Malla as an Indian sex manual in the 15th or 16th century in the Sanskrit language. The book was translated by Richard Francis Burton into English in 1885 and includes nine chapters and two appendixes. 

The "Ananga Ranga" is one of the three great erotic texts of the East. Most passages describe sexual contortions, but some pertain more to the conjuring of demons. Certain sections strangely resemble passages of the "Key of Solomon" and other ceremonial magic texts.

The poet wrote the work in honour of Lad Khan, son of Ahmed Khan Lodi. He was related to the Lodi dynasty, which from 1451 to 1526 ruled from Delhi. Later commentators have said it is aimed specifically at preventing the separation of a husband and wife.
