As emceed by the celebrated revisionist historian Bettany Hughes, the epic documentary When the Moors Ruled in Europe challenges traditional perceptions of the titular anthropological group as brutal, crass barbarians, and suggests that this image was handed down to successive generations by those who "wrote" history - the Spanish historians whose countries were invaded by the Moors. As a product of careful research, Hughes cuts against the grain of popular thought by detailing the Moors' groundbreaking advancements in such arenas as medicine, agriculture, astronomy, mathematics and architecture. ~ Nathan Southern, All Movie Guide
