12th century England, the yeomanry crushed beneath the heel of their Norman overlords. Shooting a deer to feed your family is a capital offense. The people cry out to their ancestral god to free them.
And Herne, ancient god of the forest, hears his people's cry. He calls a dispossessed young English nobleman, Robin of Loxley, to be his son and to lead his people in their struggle against Norman oppression.
This is the heady premise of Richard Carpenter's landmark Robin of Sherwood, which aired in the UK from 1983 to 1985, the first television series to be shaped by the newly-emergent paganisms of the West. In the process, it transformed forever both the Robin Hood mythos and modern paganism itself.
That's a lot to say for one TV series.
