15thc perception on swallowtail merlons?

[Koen G]

That's a good one! I will still be adding all manuscripts to the map. The Dutch site seems to be somewhat badly hastily translated though (it still contains the phrase "Pliny's Natural History" in English, as if Pliny was Shakespeare). 

Our convention for placing manuscripts on the map is to use our best guess of where the manuscript was made. S. Pietro in Ciel d'Oro appears to have been in Pavia (Milan region) rather than Padua (Veneto). So unless there is an objection, I will use Pavia as the location.
