Read this excerpt from Hamlet discussed in "Behind the Curtain." Shakespeare, in particular, had an extraordinary gift for conjuring entire worlds through dialogue alone. Take the opening scene of Hamlet, for example. Two guards—strangers in the dark—exchange terse, cautious words: Barnardo: Who's there? Francisco: Nay, answer me. Stand, and unfold yourself. Barnardo: Long live the King! Francisco: Barnardo? Barnardo: He. From this brief exchange, we learn a great deal about the atmosphere: it's nighttime because the characters are having trouble seeing each other; the air is cold because at least one of the men is wearing a cloak. How can the Early Modern English expression "unfold yourself” be paraphrased to better understand its meaning?
