Note to As You Like It, 3.5.38-39: "I see no more in you / Than without candle may go dark to bed"
I see no more in you / Than without candle may go dark to bed: i.e., As far as I can see, if you don't carry a candle, you'll have to go to bed in the dark. Behind this witticism is the widespread notion that a true beauty would light up the night, as Juliet seems to do in Shakespeare's Romeo and Juliet.
