In showing just how much was entrusted and demanded, Bernhardt reveals a governmental system at work: for anyone interested in medieval life and thought, his book is indispensable. Janet L. Nelson King's College London Rom im hohen Mittelalter: Studien zu den Romvorstellungen und zurRompolitik vom 10. bis zum 12. Jahrhundert (Reinhard Elze zur Vollendung seines siebzigsten Lebensjahres gewidmet). Edited by Bernhard Schimmelpfennig and Ludwig Schmugge. (Sigmaringen: Jan Thorbecke Verlag. 1992. Pp. xiv, 186. DM 88,-.) The core of this handsome volume is a set of revised papers from a symposium which was convened in 1987 at Augsburg, on conceptions of Rome and Roman politics from the tenth to the twelfth century (augmented by four studies, by Blumenthal, Schieffer, Schmidt, and Wolfzettel, not delivered there). It was published as a Festschrift in celebration of the seventieth birthday of Reinhard Elze, formerly professor at the Free University in Berlin, and from 1972 to 1987 director of the German Historical Institute at Rome. Professor Elze is renowned for his studies on medieval papal and imperial "Herrschaftszeremoniell" and institutions, and best known for his work on the ordines for imperial coronations. Following a laudatio to the dedicatee by Arnold Esch, and an introduction by Bernhard Schimmelpfennig to the genesis of the collection, which reaches back to a colloquium in 1982 at Dumbarton Oaks on imperial symbols and symbolism of the eighth to twelfth centuries, the essays herein are grouped under four headings: "The Emperor," "The Popes," "The City," and "Rome Seen from the Outside." The essays treat a wide variety of interrelated themes—art historical, religious, political, canonical, liturgical/ceremonial, and literary—as follows. A single contribution appears under the heading "The Emperor," by Hermann Fillitz, on real and imaginary insignia as symbols of imperial Roman dominion. Four papers are grouped under "The Popes": Werner Maleczek, on control and renovation of Rome by the papacy; Uta-Renate Blumenthal, on Rome in canon law during the period ofthe Gregorian Reform; Horst Fuhrmann, on the concepts "Roman church" and "universal church"; and Bernhard Schimmelpfennig, on the significance of Rome in papal ceremony. "The City" includes articles by Ingrid Baumgärtner, on the relation between notions of Roman renewal, on the one hand, and practice, on the other, focusing on the office ofbibliotecarius (librarian) in the context ofthe twelfthcentury Roman commune; Hans Martin Schaller, on symbols of power of the Roman commune; and Peter Cornelius Claussen, on renovatio Romae in view BOOK REVIEWS645 of eleventh- and twelfth-century Roman architecture (including twenty-two black and white plates, among which are views of the central interior of the churches of SS. Quattro Coronati, S. Clemente, S. Crisogono, and S. Maria in Trastevere [according to an early-modern drawing]). The final section comprises studies by Rudolf Schieffer, on descriptions of Rome by German historians of the tenth to the twelfth centuries; Friedrich Wolfzettel, on Rome in Old French literature, with emphasis on the late twelfth-century writer Gautier of Arras; Paul Gerhard Schmidt, on Rome from the viewpoint of the thirteenth-century Parisian scholar Johannes de Garlandia; and a final paper by Ludwig Schmugge, useful but somewhat out of place under this heading, offering a summary of the proceedings of the conference at Augsburg and the printed papers, tided "Kirche—Kommune—Kaiser." An index to persons and places will help readers to see the variety of issues dealt with in this important collection, and no one concerned with papal and imperial history from Ottoman times through the twelfth century should neglect to do so.
