Petrus Hispanus’ Tractatus, or Summulae logicales, composed in the mid-thirteenth century, came to occupy a central place in the study of logic from the late thirteenth century onward. Commented in several studia and then by Buridan at the University of Paris, it was gradually adopted across European universities—from Salamanca to Bologna, Vienna, Prague, and Kraków—and remained in use until the seventeenth century, surviving in hundreds of manuscripts and hundreds of printed editions. It served as a principal text for teaching Aristotelian and terminist logic, and its commentaries (in full or abridged form) largely supplanted those on Aristotle’s own logical works. It served as a veritable handbook for the training of Arts students, who would then proceed to the higher faculties, and it was adopted by schools across the full range of philosophical currents—Albertists, Thomists, Scotists, realists, nominalists. 

The summer school aims to survey the current state of the art and to promote further research on the Tractatus and its reception. We welcome contributions on Petrus Hispanus’ Tractatus (Summulae logicales) and its tradition that address, among others, the following themes and questions:

— The Tractatus: content, structure and sources;

— The Tractatus as a handbook and the canonisation of logic;

— Summulist logical terminology and devices: modalities, universals, kinds of syllogism, sophisms, topoi, rules, descensus, suppositio, etc.;

— The logic of the Tractatus in different disciplines (natural philosophy in its several branches, metaphysics, theology, politics, law, medicine);

— The Tractatus and the Paris-Oxford split;

— The Tractatus and other competing logical handbooks (v.g. the Summa Lamberti, the Introductiones in Logicam by William of Sherwood, the Summulae dialectices by Roger Bacon);

— Commentaries and supra-commentaries on the Tractatus;

— The reception of the Tractatus in the universities of continental Europe;

— Medieval Hebrew and Greek translations of the Tractatus;

— The reception of the Tractatus in Latin American studia and universities;

— The Renaissance and Modern replacement of the Tractatus by new textbooks and other approaches to logic;

— Contemporary view of the logic of the Tractatus;

 — The Tractatus in modern logicians and editors of logical texts (19th-21st centuries): C. Prantl, C. S. Peirce, I. Bocheński, A. Maierù, L.M. de Rijk, T. Parsons, etc.

PRESENTATION

Although the study of the Middle Ages has traditionally been approached through the prism of kingship and influenced by a State-centric nationalist logic, the decentralized nature of medieval power obliges the historian to broaden the scope of analysis, add nuance to conceptual terminology and remain mindful of this inherent trait. The conference focuses specifically on examining the relations between vassals of different religions and their lords, rather than the more common focus of relations between nobility and monarchy, although this interdependent dynamic must not be ignored as it also conditions interactions with vassals.

The geographical framework of the conference will consist of the Iberian kingdoms: Portugal, Castile, Navarre, as well as the Crown of Aragon with its extensive Mediterranean possessions. Despite important variations in jurisdiction and lordly authority throughout these regions, they offer certain common historical features that allow for a coherent comparison. Furthermore, the conference focuses on the late Middle Ages –from the thirteenth to the fifteenth centuries– to encompass the period in which the seigneurial system came to fruition.

In the context of the late medieval western Mediterranean, there were many types of lordships –noble, ecclesiastical, military orders– and the jurisdiction vested in the lords varied considerably by kingdom and according to royal concessions. Similarly, the social and legal standings of vassals were also shaped by various parameters, notably religious identity and the authority the town councils exerted over them. The category of vassals encompasses both rural peasantry and town-dwellers who were structured hierarchically, with a Christian elite that slowly came to monopolize most offices in municipal councils and took precedence over the Muslim and Jewish communities. These town councils functioned as institutionalized actors that –at least in theory– represented the interests of the vassals while simultaneously mediating the commands of their lords. Similar dynamics are to be found in the relationship between lords and their Muslim and Jewish vassals –where these exist, as well as within their political organizational entities known as aljamas or comunas. Collectively, these factors defined the complex relationships between lords and their subjects that are still insufficiently studied.

Debating the dynamics that arose between vassals of different religions and their lords can shed light on the multifaceted nature of power in the late medieval western Mediterranean. What constituted the legal and symbolic foundations of lordly power in this period? Through what mechanisms and rituals did lords display and enforce their authority? How did lords negotiate authority with Christians, Muslims and Jews? To what extent did vassals of each religion exercise agency, whether individually or collectively? To what degree were community institutions –be they Christian, Jewish or Muslim– vehicles for community representation or instruments of seigneurial control? How did horizontal dynamics –including cooperation and conflict between town councils and minority communities– shape or constrain lordly authority over their vassals?

This international conference aims to explore these issues and establish a dialogue among senior scholars and early-career researchers from various disciplines privileging a multidisciplinary focus.

CALL FOR PAPERS

Main Thematic Sections

The congress will focus on the following issues concerning the relationships among vassals and lords:

1. LATE MEDIEVAL VASSALAGE AND LORDSHIP. THEORY AND METHOD

Le numéro 273 des Cahiers de civilisation médiévale a été publié en mars 2026. Il est le premier numéro de la revue à comporter un article qui ne soit pas publié en français.

Depuis 2024, le comité de rédaction mène une réflexion sur l’opportunité d’introduire l’usage de plusieurs langues dans la revue. Il lui est apparu qu’en restant édités uniquement en français, les Cahiers de civilisation médiévale se privaient d’articles issus de milieux de recherche extérieurs au monde francophone, alors que le dialogue entre traditions historiographiques est un élément essentiel à la recherche aujourd’hui.

Toutes les langues étrangères sont désormais bienvenues, et non uniquement l’anglais. La revue reste néanmoins une revue essentiellement francophone et tous les numéros ne sont pas destinés à comporter un article en langue étrangère. Les articles publiés en français par des auteurs non-francophones continuent d’être bienvenus, afin de diffuser auprès d’un public français leurs recherches.

Comme les articles en français, les articles rédigés en langue étrangère peuvent être longs et largement illustrés. La rédaction n’acceptera en revanche pas d’article rédigé dans une langue qui ne soit pas la langue d’usage habituel des auteurs, sauf en ce qui concerne les articles en français – pour lesquels elle continuera à donner une aide rédactionnelle aux auteurs allophones si nécessaire.

Élargissement des bornes de la revue

Début 2025, les Cahiers de Civilisation Médiévale ont également élargi les bornes chronologiques de la revue, passant des X-XII^e siècles aux IX-XIII^e siècles. Cette modification, visible dans le sous-titre de la revue, a semblé nécessaire afin de refléter à la fois le contenu actuel de la revue et les évolutions de la réflexion historiographique survenues dans le champ de la médiévistique depuis la période de fondation de la revue, en 1958. S’adaptant au contenu qui est de fait celui des Cahiers, ce nouveau sous-titre a aussi été choisi par le comité de rédaction dans le but de fournir aux auteurs souhaitant proposer leurs articles à la revue une information plus juste.

La revue est toujours résolument pluridisciplinaire, et centrée sur la période romane qui est au cœur des travaux du CESCM (Centre d’études supérieures de civilisation médiévale – UMR 7302), laboratoire poitevin qui édite la revue. L’élargissement des bornes chronologiques a pour but de pointer un cadre chronologique qui soit plus cohérent avec la pluridisciplinarité de la revue, en tant qu’élément constitutif de son originalité, le XIII^e siècle (et ponctuellement le XIV^e siècle) étant déjà régulièrement convoqué dans les travaux traitant de littérature et de musicologie publiés dans les Cahiers. Vers l’amont, l’extension au IX^e siècle se justifie pour des raisons similaires, notamment pour l’archéologie, mais aussi pour ne pas exclure des articles qui prennent en compte l’historiographie qui, depuis plusieurs décennies, met l’accent sur les éléments de continuité entre IX^e et X^e siècle.

Cet ajout des IX^e et XIII^e siècles n’est pas un appel à la soumission d’articles centrés exclusivement sur ces périodes. Il vise en revanche à indiquer que des articles exploitant des sources de l’un ou l’autre de ces deux siècles pour interroger les dynamiques du Moyen Âge central ont toute leur place dans les Cahiers.

Pour rappel, les Cahiers de Civilisation Médiévale est une revue à la fois imprimée (ISSN 0007-9731) et électronique (ISSN 2119-1026 – présente sur OpenEdition et Cairn), qui propose au lecteur des comptes rendus d’ouvrages et des articles qui peuvent aller de 35 000 à 150 000 caractères, voire davantage si le sujet s’y prête. Les illustrations, même en couleur, sont aussi bienvenues, tant que les autorisations de droits sont obtenues.

Il est possible de soumettre un article à la revue à l’adresse ccm.cescm[at]univ-poitiers.fr.
