This scholarly classic looks at medieval Catholicism through the lens of pilgrimage, but from a distinctly non-Catholic perspective, which is to say, through a glass darkly. There is much here to challenge a Catholic's view of his Church history (mine, for one), from the cult of saints to the abuse of indulgences, but the book lacks a necessary spiritual dimension. Great saints and mystics, from Augustine to Bridget of Sweden, are featured not for their interiority or personal spiritual experience but rather as counterpoint to the mass movements that swirled around them . Still, more than 100 pages of end matter (notes, bib, index) suggest the depth of research that went into the writing of this book—and the rich detail that the reader will take out of it. Recommended with reservation.
