What is that circular disk which early medieval samurai wear over their swords? Is it a weight, to keep it from flopping around while horseriding?
That’s my best guess at this point. I’ve done a little research on this, but haven’t come up with answers, but my collection’s a bit thin on armor parts.
I’ve seen it in the Heiji Scroll, and a few other pre-Warring States images, but I don’t recall seeing it after about the Onin War.
I get this question every time I show my students the War Scrolls, but I’ve never had a good answer. Help?
