A historical person, in calendar years (not on the Y axis). In Episode 4 the boy plays his side: the teacher makes him "a Duke. ...And a Count." and the boy guesses the Duke's moves before he is told them. When the board becomes the Duke's box in 1858, the Duke is a living engraving, certain the prima donna is looking at him, overruling the Count's better ideas. Their talk is invented, and the teacher says so. In the box world he is still on the stage at the final position, taking the prompter's move as the one he always meant, while the queen sings Edge's account of him not listening.
