A courtezan, well dressed and wearing her ornaments, should sit or stand at the door of her house, and without exposing herself too much, should look on the public road so as to be seen by the passers-by, she being like an object on view for sale. She should form friendships with such persons as would enable her to separate men from other women, and attach them to herself, to repair her own misfortunes, to acquire wealth, and to protect her from being bullied, or set upon by persons with whom she may have dealings of some kind or another.
