Retold Not Rewritten

My girlfriend's son had to read this for school the other day, and this fit right in to our discussion about folklore being rewritten to Americanized standards.  With this Native American legend, there is no whitewashing done by Richard Vaughan.  There is no different ending to entice the readers.  There is no different structure because he felt the Native Americans didn't tell it well enough.  All he did was retell this legend and added illustrations so that children could visualize the legend themselves.  I believe it is very important to keep folklore from other cultures protected; in that it isn't restructured or rewritten.  These stories helped build cultures that still exist today and that should be discoverable by any child or human.
