Excellent post and excellent selection of legends and myth.

As a parent and teacher who specialized in children's literature I can attest to the power of literature (of any kind), espeially the one that stimulates children's imagination.

I have recently been working on a project, alongside some of my ex-students, now colleagues. We have been reading children's books in poor areas where children rarely receive that kind of stimuli.
We have also given away used books for them to own and share with their friends. Thus far it has been a very successful initiative.

I think that one of the key aspects in promoting this kind of literature is that it is a vital part of global culture. It gives kinds who are exposed to it the upper hand in developing language, cultural awareness, and critical thinking. Stories like the Trojan Horse or Robbin Hood are part of the world langauge and carry additional meanings in political, economic, and even psychological contexts. By being exposed to these stories at early age, children have the possibility of catching up with trends and ideas and develop faster the skills they'll need as grown-ups.
