"And where is Persia?"
"It is a kingdom of Asia."
"Is Darius still king there?"
"Nay, sire; he fought against Alexander the Great."
"Ah, I have heard of Alexander. He was a famous king and general, was he not?"
"Like your Majesty, he both ruled wisely and led his armies victoriously."
"And was King of Persia, you say?"
"No, sire; of Macedonia. It was Darius who was King of Persia."
The king frowned, for the slightest correction was offensive to him.
"You do not seem very clear about the matter, and I confess that it does not interest me deeply," said he. "Pray turn to something else."
