Woven Silver Cone from 10th Century Dublin

There are three separate strands of silver, each composed of between 15 and 18 wires. Yet, Halpin says, it is very hard to find where all these wires end. The visual effect is that of a single thread turning endlessly around itself. There are traces of some kind of organic material inside the cone, probably a wax shape around which the wires were woven. The visual imagination and the physical deftness required to do so are of the highest order.
