We began our lesson talking about the ancient storytelling form of the 'tale'.
For thousands of years, stories were literally told by a teller to an audience, who could refer to them directly or even engage them in the process of storytelling.
The 'completely hidden' storyteller is a relatively modern development, over the last few hundred years, which might have something to do with the invention of new types of media (including books) and increasing realism and naturalism in narrative and dramatic art.
So this idea of 'breaking the fourth wall' and addressing the audience directly is historically not unusual.
