German philologist and folklorist Jakob Ludwig Karl Grimm in 1822 formulated Grimm's Law, the basis for much of modern comparative linguistics. With his brother Wilhelm Karl Grimm (1786-1859), he collected Germanic folk tales and published them as Grimm's Fairy Tales (1812-1815).
Indo-European stop consonants, represented in Germanic, underwent the regular changes that Grimm's Law describes; this law essentially states that Indo-European p shifted to Germanic f, t shifted to th, and k shifted to h. Indo-European b shifted to Germanic p, d shifted to t, and g shifted to k. Indo-European bh shifted to Germanic b, dh shifted to d, and gh shifted to g.
Exactly who starts off a story like this? The Grimm Brothers, that's who. Three stars because of some slip-ups. For example, the son runs away from the enchantress, but later states to a beautiful princess "I fear nothing." Maybe the Grimms meant to write "Because of you, I fear nothing", but who knows?
An enchantress is paranoid that her three sons will eventually steal power from her, so she changes two into animals but the third son runs away.
The third son, our hero, is clever and takes a wishing cap away from two giants. This kind of thievery is common in fairy tales, where a hero acts like he'll be a judge on who receives a gift but takes it for himself.
The son wants to save a princess from another enchanter and is helped by his two brothers in their animal form. By taking the crystal ball after a convoluted task, the enchanter gives up and everyone is merry. It's a very weird ending - the enchanter doesn't come across as a bad guy since he's so diplomatic in his defeat.
The princess first appears an ugly old woman and a mirror reveals her true youth and beauty. Based on what I read from Grimm, mirrors don't actually pop up a whole lot so this magical effect of a normal mirror was a welcome element.
There's a lot to like about the story but the original enchantress/mother is forgotten about, and the brothers somehow know to help out the hero even though no communication was done between them. That's just the nature of fairy tales.
Kind of an odd tale, with a grab-bag of plot lines knitted together in one short story. The mother of three sons turns the two older boys into animals but the youngest of the three runs away to try to find a mysterious castle. There, a beautiful princess is imprisoned there, awaiting rescue. He must complete a series of tasks before he can free the princess. I can see someone taking this, polishing it up a bit and making a nice, more cohesive adaptation.
Found this a nice change, for once his brothers are helping him, not hindering, very rare in a fairy-tale, and perfect length in the story, just enough to the point across without drowning me in it.
