15thc perception on swallowtail merlons?

[Pierre Dumont Himself]

One important point: from my experience so far, some kind of merlons are most likely to show up in paintings of Saint George (San Giorgio), Archangel Michael (Arcangelo Michele), the Annunciation (Annunciazione), Crucifixion (Crocifissione), The Deposition/Pietà (Deposizione di Gesù), Martyrdom Scenes (Martiri), Passion of Christ cycles (Passione di Gesù), and other depictions of Jerusalem (Gerusalemme). It's rather shocking how often merlons appear in the Crucifixion and the Annunciation. Look for these when you google churches or read manuscripts.
