Did a cataclysmic event plunge humankind into the period known as the early Dark Ages? Scientists now believe the early Dark Ages may have been triggered by a natural event that occurred around 535 A.D. Science writer David Keys is convinced that the cause was a phenomenon of cataclysmic proportions. At the center of a complex chain of events seems to be "a loud bang" -- a volcanic explosion equal to "two thousand million Hiroshima size bombs." The subsequent environmental calamity, Keys believes, affected human civilization from Mongolia to Constantinople, precipitating plague, famine, death, great migration, the fall of the great Mexican city of Teotihuacan, the Anglo-Saxon victory over the Celts and perhaps even the rise of Islam.

The Battle of Towton in North Yorkshire, fought during the Wars of the Roses, was reputedly the bloodiest battle ever seen on English soil. In 1996 a mass grave of soldiers was discovered there by chance. This was the catalyst for a multi-disciplinary research project, still unique in Britain ten years after the initial discovery, which included a study of the skeletal remains, the battlefield landscape, the historical evidence and contemporary arms and armour. The discoveries were dramatic and moving; the individuals had clearly suffered traumatic deaths and subsequent research highlighted the often multiple wounds each individual had received before and, in some cases, after they had died. As well as the exciting forensic work the project also revealed much about medieval weaponry and fighting. Blood Red Roses contains all the information about this fascinating discovery, as well as discussing its wider historical, heritage and archaeological implications. (UK/PBS)
