Tribulus

[Matt Lukes]

I would think the size varied quite a lot depending on whether the tribulus was meant for infantry, cavalry or whatever. One picture I have shows tribuli varying in size by a factor of maybe as much as 40-50%. The one I chose is probably among the larger (ones made to protect from elephants, if such were ever made, notwithstanding). That's the one from Alesia. I had wondered about forge welding, but it seemed rather more difficult a method than this simple splitting, and bending of a single piece. It's interesting to hear that it was done as well.
