A gold and garnet eagle brooch atrributed to Germanic Visigoths, who settled in what is now Spain. Ah, Visigoths. They are most famous for taking down Rome in 410 AD - though it sounds like Rome was falling down anyway. And they weren't the only ones moving in to the power vacuum:
.. the Roman Empire was overrun by waves not only of Ostrogoths, Vizigoths and even Goths, but also of Vandals (who destroyed works of art) and Huns (who destroyed everything and everybody, including Goths, Ostrogoths, Vizigoths and even Vandals) ...
1066 and all that by W.C. Sellar and R.J. Yeatman
I should point out that the information on this blog is not always taken from 1930s comedy, but it's the only book I own which mentions Visigoths. If you do not care much for Visigoths or historical accuracy, I do recommend you read 1066 and All That, particularly the first half of the book (the chapters before "Anne. A Dead Queen") which are the best and funniest. As Sellar & Yeatman say:
"...The object of this History is to console the reader. No other history does this.
History is not what you thought. It is what you can remember. All other history defeats itself."
