Editions for medieval canon law

For a long time only a relatively small number of critical editions for medieval canon law existed, but during the last decades a number of important editions has appeared. Many edition were rather old. In the Patrologia Latina published by J.P. Migne canon law texts have been reprinted from old editions, but these are often not critical text editions. The situation is more positive for conciliar acts and decrees and the libri paenitentiales, the penitentials. Because of their sheer number references to them have been kept fairly general. The Decretum Gratiani (around 1140) forms the watershed between early and classical canon law. Literature on the decretal collections of the twelfth century is mentioned here, too. For all kinds of sources editions are being prepared. Some of them are in an advanced stage, among others at the Institute of Medieval Canon Law in Munich. I mention some reprints of old editions, because one cannot always consult manuscripts. Clearly these old editions are to be used with caution.

The texts in Migne’s Patrologia Latina can be searched online within the Corpus Corporum (Universität Zürich), the original volumes are accessible online in the Hathi Trust Digital Library. The Virtual Medieval Canon Law Library tries to build a single virtual location for digital resources concerning medieval canon law. It is worthwhile to search also among the manuscripts and editions digitized by the Münchener Digitalisierungszentrum. For searching patristic texts in Latin you can also benefit from the Patrologia Latina database of the ARTFL, Chicago, the Patristic Text Archive (Berlin-Brandenburgische Akademie der Wissenschaften), and the Clavis Clavium. Translations of a number of patristic and later works into German, French or English are available online in the Bibliothek der Kirchenväter (Université de Fribourg).

Councils

For the councils of the early Church new editions have appeared in the Corpus Christianorum, Series Latina (published by Brepols). There is a subseries Corpus Christianorum: Conciliorum Oecumenicorum Generaliumque Decreta (4 volumes published since 2007, more will appear (II, V, VI and VII)). For early councils an index exists by A. Weckwerth, Clavis conciliorum occidentalium septem prioribus saeculis celebratorum (Turnhout 2013). Editions of the Carolingian councils are prepared by the Monumenta Germaniae Historica at Munich and published in their series MGH Concilia, available online at their platform dMGH. The following older editions of ecumenical councils are still important:

  • Conciliorum omnium generalium et provincialium collectio regia (37 vol., Paris 1644) – councils until 1640; online, Universitätsbibliothek Paderborn
  • Labbe, Ph., and G. Cossart (eds.), Sacrosancta concilia ad regiam editionem exacta (17 vol., Paris 1671-1672) – online, Hathi Trust Digital Library – supplement by Etienne Baluze, Collectio nova conciliorum I (Paris 1683; online, Internet Archive)

  • Coleti, N. (ed.), Sacrosancta concilia ad regiam editionem exactam (23 vol., Venice 1728-1833) – online, Hathi Trust Digital Library / Universidad Complutense, Madrid (alas no link for the set); there is also a set at the Bayerische Staatsbibliothek
  • Mansi, J.D. (ed.), Sacrorum conciliorum nova et amplissima collectio (31 vol., Florence-Venice 1759-1798) – until 1439; this collection is the one most often used, reprinted and extended (53 vol., Paris 1901-1927; Graz 1960-1962); several online versions exist, for example the volumes 1-31 in Vienna, at FSCIRE; an overview of them is offered at Patristica.net

Mansi is certainly the best known, but other old editions of sources on ecclesiastical law are important. They contain not just conciliar acts and decrees, but also sermons and orations during councils

  • D’Achery, Luc (ed.), Spicilegium sive collectio veterum aliquot scriptorum (3 vols., Paris 1732-1735) – online, Hathi Trust Digital Library.
  • Martène, E., and U. Durand (eds.), Thesaurus novus anecdotorum (5 vols., Paris 1717) – online, Bayerische Staatsbibliothek, Munich.
  • Martène, E., and U. Durand (eds.), Veterum scriptorum et monumentorum historicorum dogmaticorum et moralium amplissima collectio (9 vols., Paris 1724-1733) – online, Hathi Trust Digital Library.
  • Würdtwein, Stephan Alexander (ed.), Subsidia diplomatica ad selecta juris ecclesiastici Germaniae… (14 vols., Heidelberg, etc., 1772-1780); online, Österreichische Nationalbibliothek, Vienna – see also his Nova subsidia… (14 vols., Heidelberg 1781-1792), also online in Vienna.

An introduction and a useful overview, in particular of private collections and provincial synods, is offered by Joseph Avril, ‘Les décisions des conciles et synodes’, in: Jacques Berlioz et alii (ed.), Identifier sources et citations (Turnhout 1994) 177-189. Both editions in German of Carl Joseph von Hefele, Conciliengeschichte (5 vol., 1855-1864; 9 vol., Freiburg im Breisgau, 1873-1890) have been digitized by the Bayerische Staatsbibliothek, the French translation Histoire des conciles d’après les documents originaux (12 vol., Paris 1869-1878) is online in the Hathi Trust Digital Library.

For the following (general) councils separate editions exist outside the great series mentioned above:

  • Concilios Visigóticos e Hispano-Romanos, J. Vives (ed.) (Barcelona-Madrid 1963).
  • The early councils of pope Pascal II, 1100-1110, Uta-Renate Blumenthal (ed.) (Toronto 1978).

  • Synodicon Hispanum, A. García y García et alii (eds.) (14 vol., Madrid 1981-2020).

Two CD-ROMs enhance access to early medieval canonical collections:

  • Ausgewählte Kanonessammlungen zwischen 1000 und 1400 außerhalb Italiens. Eine Aufarbeitung mittels EDV (A Selection of Canon Law Collections Compiled outside Italy between 1000 and 1400. Access with data processing), L. Fowler-Magerl (ed.) (Piesenkofen 1998; CD-Rom KANONES 1.0).
  • Clavis Canonum. Selected Canon Law Collections before 1140, L. Fowler-Magerl (ed.) (Munich 2005; MGH Hilfsmittel 21) – with a separate book length introduction; the database is now also available online and even updated with new collections.

Among early medieval canonical collection the Collectio Vetus Gallica (around 600) stands out. Its has been edited and explored in depth by Hubert Mordek, Kirchenrecht und Reform in Frankenreich : die Collectio Vetus Gallica, die älteste systematische Kanonessammlung der fränkischen Gallien. Studien und Edition (Berlin-New York 1975). Lotte Kéry, Canonical Collections of the Early Middle Ages (ca. 400-1140): A Bibliographical Guide to the Manuscripts and Literature (Washington, D.C., 1999) is the indispensable guide for the collections before Gratian.

For the wide variety of sources around the Council of Basle (1431-1438) a very useful bibliographical notice by Markus Wesche (2010) is available online at Geschichtsquellen des deutschen Mittelalters, as is an overview of primary sources at this portal, and you can benefit from A companion to the Council of Basel, Michiel Decaluwe, Thomas Izbicki and Gerald Christianson (eds.) (Leiden 2017). For the Council of Constance (1414-1418), too, a very useful online bibliographical guide exists at Geschichtsquellen, and you can benefit also from A Bibliographical Register of the Sermons & Other Orations Delivered at the Council of Constance (1414-1418) by Chris Nighman and Philipp Stump.

For synods between 1215 and 1500 you can benefit from the bibliography, repertory and digital repository of the Corpus Synodalium. Local ecclesiastical legislation in medieval Europe created by Rowan Dorin and his team at Stanford, see also the project blog. Late medieval and Early Modern Iberian councils and synods, also for Spanish America, can be traced using Max Deardorff, Synods and Councils of the Hispanic World, 1300-1700 (2022; online).

The volume with essays Creating and shaping legal knowledge in the twelfth century. Sankt Gallen, Stiftsbibliothek, 673 and its context, Stephan Dusil and Andreas Thier (eds.) (Leiden-Boston 2023; available in open access) guide you to many questions surrounding the Decretum Gratiani.

The papal decretals of the twelfth century

The collections of decretals from the twelfth century form a special subject in the study of medieval canon law. Decretals, papal judgments by delegated judges in letter form on cases of ecclesiastical law, have an intricate and complicated transmission before one finds them collected into the great papal collections such as the Liber Extra of Gregory IX in 1234 and the Liber Sextus of Boniface VIII in 1298. The early decretal collections, made by individuals, form a difficult but rewarding field of research, for which the Institute of Medieval Canon Law founded by Stephan is a very important research institute. A preliminary edition of the ninth century collection of Pseudo-Isidorian decretals, a famous conglomerate of forged texts, is available online, as are the collections created around Benedictus Levita. Eric Knibbs (MGH) tells you about current research and progress with the edition of Pseudo-Isidore. Klaus Zechiel-Eckes wrote anout the earliest decretal letters, Die erste Dekretale. Der Brief Papst Siricius’ an Bischof Himerius von Tarragona vom Jahr 385 (JK 255), Detlev Jasper (ed.) (Munich 2013; MGH Studien und Texte, 55). The Institute of Medieval Canon Law has created a database with the card files of Walther Holtzmann concerning the origin of twelfth-century decretals and their presence in canonical collections.

Other sources

Of course other sources touching the field of medieval canon law exist. The Online Medieval Sources Bibliography is one of the online resources to find other relevant source editions available in print and/or online. It is difficult to give here a sensible selection of relevant resources. For example, a very restrictive list of texts about papal elections would at least contain the following modern text editions:

  • Anton, Hans Hubert (ed.), Der sogenannte Traktat “De ordinando pontifice” : ein Rechtsgutachten in Zusammenhang mit der Synode von Sutri (1046) (Bonn 1982).
