FIGURE CAPTION
The map covers a wide area in Western Europe, between the rivers Loire and Rhine, and reports geographical names explicitly quoted by Richer.
The circles and straight lines represent Richer’s (unbiased and biased) perception radii, and Richer’s (biased) principal axes of perception.
The (red) continuous and broken lines represent respectively the approximate track of the Via Francigena (with Sigeric’s stations) and the path
of Richer’s journey to Chartres.
