The article focuses on the play "Epidicus" by Titus Maccius Plautus. Epidicus starts speaking with an imaginary voice and turns the scene into a dialogue during the soliloquy. The dialogue between them does not start in earnest until line 94 while the split between the two voices happens at the opening of the scene, when the newly introduced voice (belonging to the unmasked actor) cautions Epidicus (as the mask).
