This poem tells a folktale about an old woman who was turned into a woodpecker by Saint Peter as punishment for her greediness. Saint Peter, who was faint from fasting, asked the woman for a cake while visiting her cottage. However, the woman grew increasingly stingy and kept making smaller and smaller cakes, unwilling to part with even the tiniest scrap. As a result, Saint Peter transformed her into a woodpecker so that she would have to constantly bore into trees for sustenance, just as she bored into ever smaller pieces of dough. The moral of the story is about the dangers of greed and selfishness.
