ious traditions. Studies published since 1988 have pointed particularly to
the Waldensians in the Dauphine and Fribourg (Switz). Two essential issues
are still to be settled: why did the Waldensians embrace the Reformation? W
hat remained of their Waldensian religious past, once they had become Prote
stants?
