Ptolemy, considered a proto-Humanist by some, combined the principles of Northern Italian republicanism with Aristotelian theory in his De Regimine Principum, a book that influenced much of the political thought of the later Middle Ages, the Renaissance, and the early modern period. He was the first to attack kingship as despotism and to draw parallels between ancient Greek models of mixed constitution and the Roman Republic, biblical rule, the Church, and medieval government. In addition to his translation of this important and radical medieval political treatise, written around 1300, James M. Blythe includes a sixty-page introduction to the work and provides over 1200 footnotes that trace Ptolemy's sources, explain his references, and comment on the text, the translation, the context, and the significance.

From the time of its composition (c.1280) for Philip the Fair of France until the early sixteenth century, Giles of Rome's mirror of princes, the De regimine principum, was read by both lay and clerical readers in the original Latin and in several vernacular translations, and served as model or source for several works of princely advice. This study examines the relationship between this didactic political text and its audience by focusing on the textual and material aspects of the surviving manuscript copies, as well as on the evidence of ownership and use found in them and in documentary and literary sources. Briggs argues that lay readers used De regimine for several purposes, including as an educational treatise and military manual, whereas clerics, who often first came into contact with it at university, glossed, constructed apparatus for, and modified the text to suit their needs in their later professional lives.

Ancient Greeks and Romans often wrote that the best form of government consists of a mixture of monarchy, aristocracy, and democracy. Political writers in the early modern period applied this idea to government in England, Venice, and Florence, and Americans used it in designing their constitution. In this history of political thought James Blythe investigates what happened to the concept of mixed constitution during the Middle Ages, when the work of the Greek historian Polybius, the source of many of the formal elements of early modern theory, was unknown in Latin. Although it is generally argued that Renaissance and early modern theories of mixed constitution derived from the revival of classical Polybian models, Blythe demonstrates the pervasiveness of such ideas in high and late medieval thought. The author traces medieval Aristotelian theories concerning the best form of government and concludes that most endorsed a limited monarchy sharing many features with the mixed constitution. He also shows that the major early modern ideas of mixed constitutionalism stemmed from medieval and Aristotelian thought, which partially explains the enthusiastic reception of Polybius in the sixteenth century.

This volume brings together papers by a group of scholars, distinguished in their own right, in honour of James Brundage. The essays are organised into four sections, each corresponding to an important focus of Brundage's scholarly work. The first section explores the connection between the development of medieval legal and constitutional thought. Thomas Izbicki, Kenneth Pennington, and Charles Reid, Jr. explore various aspects of the jurisprudence of the Ius commune, while James Powell, Michael Gervers and Nicole Hamonic, Olivia Robinson, and Elizabeth Makowski examine how that jurisprudence was applied to various medieval institutions. Brian Tierney and James Muldoon conclude this section by demonstrating two important points: modern ideas of consent in the political sphere and fundamental principles of international law attributed to sixteenth century jurists like Hugo Grotius have deep roots in medieval jurisprudential thought. Patrick Zutshi, R. H. Helmholz, Peter Landau, Marjorie Chibnall, and Edward Peters have written essays that augment Brundage's work on the growth of the legal profession and how traces of a legal education began to emerge in many diverse arenas. The influence of legal thinking on marriage and sexuality was another aspect of Brundage's broad interests. In the third section Richard Kay, Charles Donahue, Jr., and Glenn Olsen explore the intersection of law and marriage and the interplay of legal thought on a central institution of Christian society. The contributions of Jonathan Riley-Smith and Robert Somerville in the fourth section round-out the volume and are devoted to Brundage's path-breaking work on medieval law and the crusading movement. The volume also includes a comprehensive bibliography of Brundage's work.

The concepts of popular consent and limit as applied to the exercise of political authority are fundamental features of parliamentary democracy. Both these concepts played a role in medieval political theorizing, although the meaning and significance of political consent in this thought has not been well understood. In a careful, scholarly, and readable survey of the major political texts from Augustine to Ockham, Arthur Monahan analyses the contribution of medieval thought to the development of these two concepts and to the correlative concept of coercion. In addition, he deals with the development of these concepts in Roman and canon law and in the practices of the emerging states of France and England and the Italian city- states, as well as considering works in legal and administrative theory and constitutional documents. In each case his interpretations are placed in the wider context of developments in law, church, and administrative reforms. The result is the first complete study of these three crucial terms as used in the Middle Ages, as well as an excellent summary of work done in a number of specialized fields over the last twenty-five years.
