The Anglo-Saxons ruled England from the 5th Century until the Norman Conquest in 1066. Now, with a metal detector, amateur treasure-hunter Terry Herbert has found an enormous hoard of buried gold and silver that one historian says "will make us rethink the Dark Ages." As many as 1500 sword decorations, crosses and other metal artifacts date back to 7th Century England, the era that celebrated Beowulf's battles with monsters and dragons. Gareth Williams is an expert on antiquities and curator at the British Museum.
