15thc perception on swallowtail merlons?

[Koen G]

Grove: the curved vs straight thing is more of a gradient , which makes it hard to draw a clear line. Moreover, sometimes the same merlons may look more straight or more curved depending on the angle (see the pink walls in Pierre's image above).

Stolfi: I'm still not sure, though Pierre may have more to tell about this some time. There is certainly a shift from strongly political to decorative, but I don't know where we are along that evolution in the early 15th century. I'm certain some of the political sting is lost by this point.

(Aside: another thing I still don't understand is the name "Guelph merlons". These are just standard merlons, basic and square. Isn't it rather that the Guelphs won't use the marked form that's associated with their adversaries?)
