In my thinking, the Rosettes folio causeways are crucial to the identification of the page as a map. And it is my contention that most researchers, especially those who think the page is not a map, completely ignore these causeways.
So, I thought I would go through the causeways one by one. Here below to start off is one of them. I think that this causeway represents a map or what one might call a sub-map, as I believe it constitutes part of the larger map that is the page in itself, but also serves as a small map in its own right.
If you are interested in my precise interpretation of this causeway map then you can find it on my full annotated analysis of the rosettes folio which is available to download.
For this causeway and most of the others, non-map theorists seem to have no interpretation of the specific peculiarities of this causeway drawing and, in fact, seem to be quite happy to ignore them. Yet this causeway like many of the others is very distinctive in its own right and I doubt that the author drew it the way he/she/they did for no reason whatsoever.
The following causeway below has lots of specific details and yet those who view the page as not being a map seem quite happy to ignore all or most of them.
I, again, believe that this causeway constitutes a sub-map or map in its own right and part of the larger map which is the page as a whole.
Again my interpretation of those details can be found in my annotated image of the page.
The following causeway below I believe to be another sub-map or map in of itself as part of the larger map that is the whole page. This has many specific details and yet these details and their interpretations seems to be something that most researchers who comment on this page seem to be quite happy to ignore and essentially dismiss as meaningless.
My own interpretation can be found elsewhere as described.
As I have stated elsewhere I view the rosettes causeways very much like the strips that comprise Matthew de Paris's stripmap of his journey from London to Jerusalem.
As is clear these causeways on the rosettes folio are quite distinct and different. If they all are essentially meaningless then why did the author pay for such a large piece of vellum to illustrate lots of details that have no meaning? If they have a meaning what is that meaning other than the specific geographical details of a map?
The following causeway below I regard as a being another sub-map or map in and of itself, which constitutes part of the larger map. I believe that all the details we see in this drawings are architectural or geographical. When one looks closely there are more specific details that I think need to be explained than at first glance.
I created a specific thread for causeways as I believe that this topic is woefully under-discussed.
The following causeway below has a number of very specific details, which rarely or never are discussed. I believe it represents another sub-map or map that constitutes part of the larger part that is the page.
My own interpretation I have discussed elsewhere.
I have broken down the page into specific parts and images as I wonder if the whole page is so large and so detailed that it is difficult for people to come to terms with.
Even the two least detailed causeways from the Bottom Centre to Bottom Right and also the Bottom Right to the Centre Right show some specific details, which I believe are consistent with the map interpretation.
Obviously it is not only the causeways that fit the map interpretation, but also the Top Right Rosette fits the interpretation of the page as a map. And I would also say that the Bottom Left rosette fits the map interpretation, if one accepts that the blue and white wavy lines represent bodies of water.
