If one looks at a map of all the present Camino routes, all have one thing in common - they ultimately terminate at Santiago de Compostela. Again. looking at the map of routes, one cannot but notice that for most of the routes, the
Camino Frances is the spine or backbone of the Camino.
All paths may lead to Santiago, but perhaps half of them eventually join and merge with the
Camino Frances. The begin literally all over Europe. I think this might be the origin of the feeling many people have for regarding the Frances as "the Camino."
Similarly, St. Jean Pied de Port has the historical reputation for being THE starting point for the
Camino Frances. I think, again if you look at a map, this is simply because the town sits on the French side of one of the three passes through the Pyrenees Mountains. Many Camino routes starting in northern, western, or eastern Europe converge at St. Jean for the walk into Spain and joining the Spanish segment of the
Camino Frances at Roncesvalles.
Again, in a similar manner, I suggest this is parenthetically, also where the scallop shell analog as a description for the Camino, writ large, developed. Many paths from many different points of origin, all converging on one end-point, Santiago de Compostela.
In 1214 Saint Francis of Assisi walked the
Camino Frances (named NOT because of St. Francis but because it originates in France) from Puente la Reina. He came on the Camino Aragones from the eastern (Somport) pass across the Pyrenees. Since about the year 850 +/-, kings, political figures, Popes, writers and philosophers have also walked some or all of this central spine common to many of the Camino routes.
Paulo Coelho documented his Camino along the Frances in his writings. Several movies (more than The Way) have been made in various languages - mostly about the Frances. So, I suppose the
Camino Frances has become the metaphor for "the Camino" over the millennia.
To be sure the
Camino Frances is not the only Camino. It may not be the most physically challenging, the most scenic or beautiful (that is subjective), the longest, or the "best" (again subjective). However, it is sort of like telling someone that you have been to Paris. They usually envision the Eiffel Tower and proceed to ask you if you saw the Eiffel Tower. When you tell someone you have or will walk the
Camino de Santiago, people who have heard about it in any form, are likely to presume you MEAN the
Camino Frances.
