I don’t think prostitution is the world’s oldest profession. For most part of human history men have lived as hunter-gatherers. No instances of prostitution are seen in societies organised in this manner. It is a fact, however, that a similar phrase is found in the morality play “The Fall of Rightness” (c. 1340). Cain, having been exiled, is wandering in the wilderness when he is visited by Lilith, an agent of Satan. Her function is to explain to him the nature of the post-Fall society he is to encounter and, during her description of the world of sin, she says:” Whoredom is the original busines of woman”. This is a statement that, of course, can be taken as an example of medieval misogeny rather than a statement of fact!
