Linothorax vs Quilted linen vs spolas

[PMBardunias]

Although the view here is from the rear, the corselet could still be a 'one-piece' Tube-and Yoke' ( of which there are many representations) and from the front would still have the characteristic shoulder-pieces....

I didn't mean to imply that the armor depicted is not a T-Y, the opposite actually. If a quilted T-Y could be presented with such detail, it begs the question of why we see no evidence of quilting on the vast majority of T-Ys. Perhaps stiff panels of close stitched quilting under a shell? But it does at least show that there is no single construction method and that quilting was a viable option, though most may have been leather.
