Anglo-Saxon art before the time of Alfred (who ruled from 871–899) is a mixture of Anglo-Saxon and Celtic techniques and styles. The Sutton Hoo treasure is an excellent example of very early Anglo-Saxon metalwork and jewellery. It came from a royal grave of the early 7th century. The period between Alfred and the Norman Conquest saw a distinct Anglo-Saxon style in art. This was due in part to the revival of the English economy and culture after the end of the Viking raids. This later style appears to have been in touch with trends in western Europe.
