Two neighbors came before Jupiter and prayed him to grant their hearts’ desire. Now the one was full of greed, and the other eaten up with envy. So to punish them both, Jupiter granted that each might have whatever he wished for himself, ut only on condition that his neighbor had twice as much. The greedy man prayed to have a room full of gold. No sooner said than done; but all his joy was turned to grief when he found that his neighbor had two rooms full of the precious metal. Then came the turn of the Envious man, who could not bear to think that his neighbor had any joy at all. So he prayed that he might have one of his own eyes put out, by which means his companion would become totally blind.
