吟遊詩人ビードルの物語 The Tales of Beedle the Bard

I'm curious about the selection process for these stories and whether they were inspired by existing folklore or entirely original creations.

The tales seem simple on the surface but carry deeper messages. What moral lessons stood out the most for others?

The artwork adds such charm to the tales — I wonder if the illustrator aimed to evoke a particular mood or era.
