An old man wanted to leave all of his money to one of his three sons, but he didn't know which one he should give it to. He gave each of them a few coins and told them to buy something that would be able to fill their living room. The first man bought straw, but there was not enough to fill the room. The second bought some sticks, but they still did not fill the room. The third man bought two things that filled the room, so he obtained his father's fortune. What were the two things that the man bought and what was able to fill the room?
The wise son brought a candle and a box of matches. After lighting the candle, the light filled the entire room.
500 at the beginning, 500 at the end,
5 in the middle is seen,
The first of all letters, the first of all figures
Take up their stations between,
String them all together, and you will see
The name of an ancient king.
