15thc perception on swallowtail merlons?

[Mark Knowles]

I am so glad that you have undertaken this exercise as it is something that I think needed to be done for a long time. It is something that I tried to do a few years ago, myself, but much less thoroughly. Although to be fair to me in my approach swallow tail merlons were only part of my consideration as I was also focused on geographical features especially those related to water.

My interest in this exercise may seem surprising as I already have an opinion as to where the two sets of swallow tail merlons represent as I have discussed on Nick Pelling's blog(Castello di Porta Giova in Milan, Murata in Bellinzona).

An another, probably more difficult, but similar exercise would be to consider the other buildings and where buildings looking like them are to be found.
