At its worst, microhistory is merely antiquarian button counting. But at its best, as exemplified here, small things serve as touchstones for studies of wider-ranging significance. McCormick examines the Basel Roll, a ninth-century manuscript relating the information gathered by envoys of Charlemagne, who inquired into the financial needs of churches in and around Jerusalem. The roll preserves three documents that provide personnel numbers and sizes of building roofs in area churches and monasteries, as well as partial annual expenditures for the patriarch of Jerusalem...McCormick shows that the Jerusalem church had shrunk since late antiquity; that contemporary Frankish houses were larger and richer; and that Einhard did not exaggerate Charlemagne's interest in faraway Christian communities. Among the many strengths of the book is the full-size facsimile of the Basel Roll included as a stand-alone poster.-- (11/01/2012)Biografía del autorMichael McCormick is Francis Goelet Professor of Medieval History at Harvard University.
