I've just finished The Second Maiden's Tragedy. (Yes, I'm flying through them now.)
This play's authorship is contested, but the general consensus seems to be that it's the work of Thomas Middleton. It's part of the Shakespeare apocrypha as it was loosely attributed to Shakespeare in the 17th century. By virtue of the fact that his name was scribbled upon the manuscript by someone (the play was never printed). However, two other names (Thomas Goffe and George Chapman) also had the same honour. So such scribblings are likely estimated guesses or wishful thinking on the part of the various scribblers.
A tyrannical king, simply named Tyrant in the play, tries to woo the lady of the former king he's usurped.
"He's lost the kingdom, but his mind's restor'd ;Which is the larger empire ? pr’ythee tell meDominions have their limits, the whole earthIs but a prisoner, nor the sea, her jailor,That with a silver hoop locks in her body ;They're fellow prisoners, though the sea looks bigger,Because it is in office and pride swells him ;But the unbounded kingdom of the mindIs as unlimitable as heav'n , that glorious court of spirits."
