How is scene one used for exposition?

The first scene introduces Brother Jero as a confident, self-righteous character with little conscience. He has no qualms about deceiving his old tutor, and is confident in his ability to convince the audience that his actions are warranted. Soyinka makes clear that he speaks with "accustomed loftiness," emphasizing that he is well versed in the art of influence, which Jero aims to show the audience by presenting them with a day of his life.

Also important is the managerial nature of Jero's profession and the language with which he discusses it. Jero must sell his prophecies like a businessman, eagerly convincing the audience of his authenticity and capabilities. Yet he also admits to recent hardships, posed by modernity, in what he calls "the trade." Already the audience has a sense of Soyinka's satire, as Jero's entire sense of self is built off a phony prophecy and actions unbefitting of a true prophet.
