At the moment in which he arrived at the palace and announced himself, the king gave orders for him to be allowed to enter.
"Have you thought out the answers to the questions that I asked you?" asked King Pedro.
"Yes, sire."
"Well, begin then. What is the distance between the earth and the sun?"
"Eight hundred and forty-seven thousand leagues. Not one more, nor one less. And if your majesty does not believe me, have it measured."
As this was impossible, the king was obliged to say that he was satisfied.
"Not bad," he said. "Now the second: How much am I worth?"
"Twenty-nine pieces of silver."
"And why twenty-nine pieces?"
"Because your majesty is not worth so much as our Saviour, Jesus Christ, and He was sold for thirty."
