Unfortunately, it has brought about a slight narrowing of options, but this isn't necessarily a bad thing! During the first century AD we see a new style of torc (or more accurately, neckring) appearing in the South West of Britain, hinged at the back, fastening at the front, with examples from Wraxall and Pentire. As the century progresses, and moving into later centuries, we see this style extend across Britain, but it starts down here! I had previously been planning a copy of the Pentire Neckring (shown below), but as our new focus starts earlier than the beginning of the century, I have had to reconsider.
An interesting question is raised, however, by the Bryher Burial on the Isles of Scilly, which is a warrior grave, complete with shield and sword, dating from the first half of the 1st Century BC. It is normally assumed that torcs would be worn by high status individuals, but this burial has no torc, but a very nice sword, and a beautiful bronze mirror, both suggesting a high status individual! So perhaps the torc is not quite so ubiquitous for Iron Age British warriors...
What is present, however, is a nice copper alloy spiral ring, of a style found worn by both males and females as both finger and toe rings, although not in great numbers.
This has led me to brave my way out to Dave's workshop in the woods and make a couple of rings, one in copper (for Melistia), and one in bronze (for myself.)
The other new toy I returned from Dave's workshop with this weekend was a nice replica currency bar, based on the style found in Coffinswell in Devon, dated to the 1st/2nd Century BC. Around 80 or so (estimated over 100 originally) were pulled out of the ground in 1991 after a local farmer kept ploughing up the rusty iron bars.
The only reason we know what they were used for is because Caesar writes in his 'Commentaries' that the British tribes used iron bars as well as coins as currency. So, we might not have any shiny coins minted in Dumnonii territory, but we do have currency you can beat a mugger off with... Proper job!
