Berkeley: University of California Press, 1979. First edition. Hardcover. Fine. Massive and exquisite production from the University of California Press. Three volumes plus the original prospectus still in the envelope. This set is as new. It remains in its original shipping box. Bound in light tan cloth with red leather spine labels, lettered in gilt. Issued without dust jacket. This monumental effort was accomplished based entirely on the existence of a 9th century drawing of a Benedictine compound - a small walled city if you will - containing church, infirmary, houses, stables. It looks to my eye like an much expanded plan for what became eventually the original Colleges of Oxford or Cambridge. From five parchment sheets sewed together, this plan has survived and remains a topic of intense scholarly dispute. It is believed that the late and much missed Umberto Eco referenced St. Gall in his "The Name Of The Rose." The structure was never built and thus we are left with the faded red ink drawing of the ideal Medieval Monastic complex. These volumes are acknowledged as the finest study in English to date. This is as fine a set as one could hope to find.
