This quote has been also attributed to

- Cicero (Orator and statesman of Ancient Rome)
- Pascal Blaise (French mathematician, physicist, and theologian)
- Voltaire (French philosopher)

That's something that's never gonna be resolved, except someone comes up with that ancient letter. Therefore, everybody seems to prefer their compatriots :)
