Cervantes, Don Quixote
, Part II, Chapter XII (tr. Walter Starkie):
"Now tell me, have you never seen a play acted in which kings, emperors, pontiffs, knights, ladies, and divers other characters are introduced? One plays the bully, another the rogue, this one the merchant, that the soldier; one the wise fool, another the foolish lover. When the play is over and they have divested themselves of the dresses they wore in it, the actors are all again on the same level."
"Yes, I've seen it," answered Sancho.
"Well, then," said Don Quixote, "the same happens in the comedy and life of this world, where some play emperors, others popes, and in short, all the parts that can be brought into a play; but when it is over, that is to say, when life ends, death strips them all of the robes that distinguished one from the other, and all are equal in the grave."
"A brave comparison!" said Sancho. "Though not so new, for I've heard it many a time, as well as that one about the game of chess. So long as the game lasts, each piece has his special office, and when the game is finished, they are all mixed, shuffled, and jumbled together and stored away in the bag, which is much like ending life in the grave."
