Hmmm...all this about which map to use and how they connect...I would like to call your attention to another map...the Carte Cassini...http://cassini.ehess.fr/cassini/fr/html ... gation.php
Click on the map for the department of Aude (having selected Department from the menu below) and then move the map around until you locate yourself in the Rennes area.
"Full Title: ((Composite of) Carte de France. Levee par ordre du Roy. (1750-1815)
Author: (Cassini, Cesar-Francois, 1714-1784); (Cassini family)
The Carte de France was published by four generations of the Cassini family from 1750 to 1815. It consists of 182 sheets at the same scale, allowing the sheets to be joined together to form a physical map of about 39 feet high by 38 feet wide. It is rich both in historical cultural information and exquisite graphic art. The map was the first national survey completed systematically, relying on the latest science of its time."
So in 1750 this is what they saw, noted and recorded. There is a church at St Just, there is a church at Bezu...there is a church at Rennes...there is nothing to note a chateau in the Bezu area (further up the Aude river one can see the notation Chau where the Aude intersects another stream, between Escouloubre and Rouze, as well as another slightly before there, on the other side of the river, between Campagnn and Fountanes). If the Albedun chateau were more than barely noticeable ruins, it would have bee noted (the ruins at Usson les Bains were preserved, the ones between Campagne & Fontaines (modern names) were not--although they did figure in Cathar history.
The first time I saw the church at Bezu was in 2001...one could recongize it as a church but it was in very poor condition (stone-wise) and covered in vines. Two years later the walls were repointed, repares and replastered and the vines gone.
Someone living nearby had a key if one wanted to look inside... I didn't. I like my ruins 'unimproved'.
Myself, I wonder who managed to get possession of the old church (yes, they did a lot of work, inside and out) and what they might have found....there.
While I think it's great to use one's intelligence and time to explore all sorts of possible scenarios and possibilities, I base my involvement on what I have experienced 'on the ground'...what I have been drawn to, or warned away from while in France. I have been drawn to places that are barely discernable on a good map (with very fine resolution). It isn't what I find physically that matters. The search and the discovery that there was 'something' there made it all worthwhile.
My treasure hunt? "Les hauts lieux ou souffle l'Espirit". (accent grave on the 'ou').
But do take a look at the map. You will see the Rennes area with different eyes. Sometimes google maps show too much and too little. The Cassini shows not just what they found, but in their accountings, one can see history as well.
Well if you look at that map you linked to over to the left of Bourges is the Chapel of St Ursin and Philippe de Cherisey in the journal Circuit drew our attention to this
St Ursin is the centre of France.
It is in the former department of Berry and there is a manuscript from that area known as
The anatomical ZODIAC of man.
Eirene is Greek for the Roman PAX.
