I happened to watch 2 movies in the same week ("Live and Let Die" and "Scorpion King") both of which had a common trope of a fortune teller virginal female who is supposed to lose her prescient powers upon physical intimacy (having sex, to put it crudely), though in the former the powers were lost and in the latter the prediction ended up being a fake invented by the fortuneteller bloodline to protect against kingly advances.
What is the cinematic origin (first use) of this trope?
