I've been drafting an article for the principality newsletter, and it got me to remembering something I'd been thinking when working with Egerton 1146: that, despite our writs and scrolls being framed rather than bound, we tend to follow exemplar patterns of one border heavier/thicker than another. What's more, I've found myself, and noted many others doing the same, we tend to favour the verso setup of a thicker left-hand border, rather than the recto. (Vast generalisation, of course, but still). If we completely leave out the side of a border, again, we tend to leave out the right-hand side, privileging the verso layout.
I find this very interesting. Any thoughts? Are we just sinister scribes?
