In this week's blog I take you with me on a little journey to one of the most outstanding form of art within Viking Age jewellry: the tortoise brooch.
Some years ago I had the luck of my collecting life to be able to aquire one and it is still one of the cornerstones in the collection. At this moment, it is on display on the exhibition 'The Norsemen were here' in the Historiehuis in Roermond (south of Holland) http://www.historiehuis.nl/
Although described in more detail here, I'd like to address this beauty piece of art also in this blog.
Viking tortoise brooches, more in specific, tortoise shell brooches in the beginning were domed and far more 'flat' (as 'flat' is a big word here). The further in time in the Viking Age, the more elaborate and 'outbuild' the tortoises did get. The example I have is from the Petersen's P52/P55 type, wich dates him in the second part of the 10th century.
For years I have thought it was gilded originally, as I have seen on several - the most bling-bling examples who had survived - in the National Museum of Norway in Oslo.
At one day the brooch developed a whitish surface and I consulted an archaeological expert in conserving and cleaning and treating artefacts. The developing white surface happened to be an early phase of bronze disease. Luckily I was just 'in time' treating this piece (see for some general advice to collectors on the page on the object where I have linked to above).
The archeaologist said that this viking tortoise brooch never was gilded. Obviously there were non-gilded and gilded types in the day. In my opinion the use of tortoise brooches may seem to have been widespread, it must have something in use with the more 'upper class' Viking Age woman. A few thousand have been excavated, in more or less complete state. Turning up in antique market just a few times in the last 10 years, addresses their rarity also.
On the images beneath in following order:
- an image of the tortoise, taken in 2009 when I aquired it;
- an image of the diverse types of tortoises brooches during the 9th and 10th century;
- images of the tortoise after treatment (mention the needle wich popped up when all the rust was cleaned away ! Being hollow on the inside and the remaing iron on the inside, it was filled up with a form of plastic to be able to preserve it).
- an image of how the tortoises were worn..

A short overview of the types of tortoise brooches in 9th and 10th centuries..
The back of the tortoise brooch after cleaning with a good part of the needle intact.
It is an example wich was found in Karelia, Finland. One could addres this type as 'Viking-Age Finnic'.
An example of this type was on auction a few years ago. See here.
Finally, take a look at this rare matched pair of oval tortoise brooches who were also on auction a few years ago..
