In all fairness the TV series 'Robin of Sherwood' also included a moor as a
member of the merry men. However to the best of my knowledge this is a modern
addition with no basis in the ballad tradition - which admittedly doesn't make
it a bad idea. There were also witches, wizards and a pagan god in RoS - but
of course they did it well.

Hadn't Mayan civilization already crashed and burned well before the Conquest?
