Query: THIS DOCUMENTARY SEEMS TO HAVE RATTLED A FEW FEATHERS

This documentary focuses on a period in Spain's history (711 A.D - 1400's [a period of Muslims from North Africa rule -- Moors]) that is being consciously wiped away -- in Bettany Hughes estimation. One thing this video is not is an argument against Christianity. Visually, we are able to see some of the great structures built by the Moors: the Córdoba for one, along with a layman's explanation of the geometry that went into its construction. We are able to see ancient texts with translation and additions to Greek philosophy. But Miss Hughes went as far as interviewing the Duchess of Medina Sidonia. The Duchess pulled up documents from the 13th century showing that her ancestor -- the great Guzman El Bueno -- was a Muslim of Moorish decent. The quality of the video is sharp and Bettany Hughes style honest and engaging. I highly recommend this documentary.
