Cristoforo Colombo

Father Perez: I see you're a scholar, my son, as well as a traveler.

Christopher Columbus: Certainly a traveler, Father. I've sailed as far north as Iceland, as far south as Guinea, and eastward to the Golden Horn.

Father Perez: But that is to have reached the limits of the World.

Christopher Columbus: Of the known world? Yes, Father, but the actual world... not by a thousand leagues.

Father Perez: How can you say that - never having seen it?

Christopher Columbus: Have you ever seen Heaven or Hell?

Father Perez: We have sound reasons for believing they exist.

Christopher Columbus: I have sound reasons too.

Father Perez: What are they?

Christopher Columbus: The same as yours, Father, and revelations to which I can add cosmography and mathematics.
