This map is a lucky find of mine, from the 1885 book En suivant Jeanne d’Arc sur les chemins de France. It was shipped to me from Lorient Bretagne of all places (a separate story!)
The maps, with some deviations, follow the same routes as described by Frances Caddy who travelled them personally on foot and by bicycle the next year, 1886. Her very-well documented account was published in London under the title Footsteps of Jeanne d’Arc: A Pilgrimage.
The print quality is very good.
It is fairly easy to transfer the routes into Google maps and Garmin. The job, however, is daunting when it comes to actually following them on a bicycle.
