Here's my take on Grimm brothers' tale "Iron John".Iron John was a king wo was once transformed into a forest creature with a skin red like rust (the origin of his nickname). One day he was captured by another king and put in jail. It's the king's son himself (the little boy on his back here) who set him free and left the castle with him to live in the forest ...This is just the beginning of that nice tale of course, many things happened after that, but it is better to read the tale
