There are three systematic collections associated with bishop Ivo of Chartres the earliest of which is a collection edited in 1561 and known since then as the Decretum. The other two are the ''Collectio B''  [{{FM|194}}] of the ''Tripartita'' and the ''Panormia'', both dependent on the Decretum. One of the abbreviated versions of the Decretum attributes the collection to Ivo. In the Ms Cambridge, Corpus Christi College 19 there is a 13th century ascription to Ivo and in the Ms Paris, BnF, lat. 3874 a late ascription to him as well. The collection is divided into 17 parts in most of the manuscripts, in others the final part is missing.


The first edition was published by Jean van der Meulen (Molinaeus) in 1561 at Louvain. His edition was based on two copies, a „codex regius“ and a Cologne manuscript which no one has been able to identify. The surviving manuscript closest to the edition is Vat. Pal. lat. 587. Jean Fronteau published in Paris in 1647 a second, inferior edition as the first volume of the ''Opera omnia'' of Ivo. This second edition was reprinted in {{Author|Migne PL}} 161. 47–1036. At present Martin Brett is preparing an annotated copy of this edition. The draft of the text, with identification of the formal sources, will become available on his web-site; this is much needed. One of the most important reasons is that the rubrics in the copy in the ''Patrologia latina'' are not those found in the manuscripts.
There are three systematic collections associated with Bishop Ivo of Chartres: the ''Tripartita'', the ''Decretum'', and the ''Panormia''. Only the ''Decretum'' can be linked with certainty to Ivo, who began to collect material when still at Saint-Quentin and had a mature version of the collection at hand in 1095.


The most recent text in the Decretum is a letter that pope Urban II sent to Grenoble sometime between 1091–1093. Christof Rolker has compared the content of the collections attributed to Ivo with the canons that Ivo cites in his letters. Peter Landau divides the surviving copies of the Decretum into a French and an English group, not on the basis of where they were made, but rather on the basis of their present location. The copies in his so-called French group are found in the Mss Paris, BnF, lat. 14315 (near Chartres according to Brett) and Vat. lat. 1357, which is very close to that of the Paris manuscript. The present analysis is based on the Ms Paris, BnF, lat. 14315 ({{Coll|ID}}). Landau has established that the „French“ version was used in compiling ''Collectio B'' of the ''Tripartita'', the ''Panormia'', the ''Collectio S. Genoveve'' and a collection on fol. 314r–393v of the Ms Paris, BnF, lat. 4809.
== Structure and content ==
The ''Decretum'' is one of the most comprehensive systematic collections of canon law of the Middle Ages. The material (approximately 3760 canons) is organised thematically into seventeen books of varying length. The first two books are devoted to the sacraments, followed by individual books, for example on the ecclesiastical hierarchy (Book 5), marriage law (Book 8) and a book ‘on lay matters’ (Book 16: ''De officiis laicorum''); the last book is devoted to speculative theology. In general, canon law and theology are inseparable in Ivo's work; the ''Decretum'' contains an extraordinary amount of theological material (above all, from the writings of St Augustine).  


Rolker has examined the appendix of three folia at the end of the Ms Vat. lat. 1357 (fol. 244va–247rb). It is written in the main hand and contains the canons found in the „English“ copies. The appendix also contains material suggesting a provenance in northern France in the last third of the 12th century.
Ivo wrote a prologue to the ''Decretum'' that is found with all copies of his collection but also a number of other collections; almost all ''[[Panormia]]'' copies, the ''Panormia''-derivative ''[[Collectio X partium]]'', one ''[[Collectio Tripartita|Tripartita]]'' copy, an [[Exceptiones ecclesiasticarum regularum|abbreviation of Gratian's ''Decretum'']], and other works all begin with Ivo's prologue (which also was copied as part of his epistolary and enjoyed a separate circulation).


The „English“ copies are in the Mss Cambridge, Corpus Christi College 19 (Brett describes the script as Anglo-Norman minuscule), London, BL Royal 11. D. VII and the Ms Paris, BnF, lat. 3874 (Colbertine). Brett specifies that the London Royal copy is related to, [{{FM|195}}] but not a direct copy of the Cambridge copy. An English copy was used by the compiler of an excerpted form of the Decretum which survives in several manuscripts: Rome, Biblioteca dell’Accademia Nazionale dei Lincei Corsini 41 E 1 (1808); London, BL Harley 3090; Vienna, ÖNB Cod. 2196 and Leipzig, UB 955. Related to the English group is the Ms Vat. Pal. lat. 587, which breaks off with canon 6. 432.
== Formal sources ==
The ''Decretum'' contains almost all material found in the [[Burchard of Worms, Liber decretorum|''Liber decretorum'' of Burchard of Worms]], and the division of the books is clearly inspired by Burchard. Ivo and his collaborators presumably used two different versions of the ''Liber decretorum''; [[Chartres, BM, 161]] is closely related to one of the copies they used. While Burchard's collection is comprehensive, it contributed only about half of the material that Ivo included in his own collection. The most important major sources are [[Collectio Tripartita#Tripartita A|part A of the ''Tripartita'']] and the ''[[Collectio Britannica]]''. The first of the two so-called [[Collectio canonum in Paris, Bibliothèque de l'Arsenal, 713|Arsenal collections]] is the best witness of the working materials Ivo and his team must have produced in the course of compiling the ''Decretum''. It served as a preparatory collection to the ''Decretum'' in that it contained most non-Burchardian materials that ultimately were included in the ''Decretum''. Another preparatory collection was a florilegium on the Eucharist Ivo had compiled when still canon at Saint-Quentin. Among the smaller sources, Ivo used Nicholas' ''Responsa'' perhaps from a manuscript related to [[Città del Vaticano, BAV, Vat. lat. 3827|Vat. lat. 3827]], the [[Collectio canonum in Chartres, BM, 193|collection of Chartres, BM, 193]], and the [[Collectio canonum in Paris, BnF, lat. 13368|''Collectio canonum'' in Paris, BnF, lat. 13368]].


The 17th and final part of the collection, which is found in most of the complete manuscripts (''Speculativas sanctorum patrum sententias de fide, spe et caritate''), is missing in the Ms Paris, BnF, lat. 3874 and in the group of excerpts based on the English group mentioned above. According to Landau this probably represents an early shorter form. The 17th part is not to be found in two important immediate derivatives of the Decretum either, the ''Tripartita B'' and the ''Panormia'', nor is there anything of this part of the collection in the Ms Paris, Bibliothèque de l’Arsenal 713, one of the major sources of the collection.
== Editions ==
The first edition was published by Jean van der Meulen (Molinaeus) in 1561 at Louvain. His edition was based on two copies, a „codex regius“ and a Cologne manuscript which no one has been able to identify. The surviving manuscript closest to the edition is Vat. Pal. lat. 587. Jean Fronteau published in Paris in 1647 a second, inferior edition as the first volume of the ''Opera omnia'' of Ivo. This second edition was reprinted in {{Author|Migne PL}} 161. 47–1036. At present Martin Brett is preparing an edition he makes available at https://ivo-of-chartres.github.io/decretum.html
== The ''Decretum'' in the ''Clavis'' Database ==
The present analysis ({{Coll|ID}}) is based on [[Paris, BnF, lat. 14315]]. Landau has established that the „French“ version was used in compiling ''Collectio B'' of the ''Tripartita'', the ''Panormia'', the ''Collectio S. Genoveve'' and a collection on fol. 314r–393v of the Ms Paris, BnF, lat. 4809.


Brett has identified the canons that the compiler of the ''Collectio Caesaraugustana'' took from the Decretum and established that that compiler used an early version of the Decretum which contained canons found only in the „French“ as well texts found only in the „English“ version. He points to the fragmentary copy of the Decretum in the Ms Sigüenza, Archivo de la Catedral 61 as a possible example of such an early, more complete version. On the basis of the recent work of Christof Rolker, however, this might mean a „French“ or „English“ copy with an appendix.
==Extant Manuscripts ==
Only a relatively small number of complete copies have survived, but as relatively many fragments make clear, the impact of Ivo's collection was wide and rapid; already in his lifetime, it was read, used, and copied well outside his diocese.


There are further abbreviated forms of the Decretum in the Mss: Leiden, Bibliotheek der Rijksuniversiteit 184; Lincoln, Cathedral Library 193, fol. 1–158; Antwerp, Musaeum Plantin-Moretus M.144, fol. 90–146v (from Oxford) and Plantin-Moretus M. 227, fol. 80r–154v.
===Sigla of the edition===
The ''sigla'' for the major manuscripts in the following table are those of the edition by Martin {{Author|Brett}}.


The Decretum is accompanied by a prologue sometimes used also for the ''Panormia''. Jean Werckmeister calls Ivo, on the basis of this prologue, the first true canonist because it deals theoretically with such essential aspects of canon law as reconciliation of apparent contradictions, immutable and contingent law, dispensation and judgment versus mercy. The prologue refers to the collection itself as a ''Liber extractionum sive excerptarum ecclesiasticarum regularum partim ex epistolis Romanorum pontificum, partim ex gestis conciliorum catholicorum episcoporum et regum''. There is still no agreement about which collection the prologue originally belonged to, however. Franz Bliemetzrieder thought the prologue was written expressly for the Decretum, Paul Fournier that it was written for the ''Panormia'', [{{FM|196}}] Bruce Brasington that it was an autonomous treatise. Christof Rolker notes that the prologue draws on material in the ''Collectio A'' of the ''Tripartita'' and Decretum, but not on material specific to the ''Panormia''.

=== English vs. French manuscripts ===
{{Author|Landau}} divided the surviving copies of the ''Decretum'' into a French ('''P''' and '''V''') and an English group ('''C''' and '''R'''). As {{Author|Brett}} has shown, '''P''' and '''V''' share many readings against '''C''' and '''R''' (and vice versa). There are also some texts found in group but not the other. While there is some evidence that the exemplars behind '''PV''' and '''CR''' were reworked independently (when eliminating doublets, they made different choices), the workshops producing these two versions were apparently in contact with each other ({{Author|Rolker}}). An appendix of three folia at the end of the French Vat. lat. 1357 (fol. 244va–247rb), written in the main hand, contains the canons found in the „English“ copies.  


The most recent listing of the sources was made by Martin Brett. The major sources are the ''Liber decretorum'' of Burchard, the ''Collectio A'' of the ''Tripartita'', the ''Britannica'' and the collection in the Ms Paris, Bibliothèque de l’Arsenal 713. The compiler of the Decretum  [{{FM|197}}] used most of the canons in the ''Liber decretorum''. I have shown elsewhere that both the French and the Italian versions of Burchard were used or at least a mixed version. As for the ''Collectio A'', Brett notes that if it was compiled merely as preparation for the Decretum, the compiler was wasteful to the point of extravagance. Brett also points to the gap between the Decretum and the ''Tripartita'' „both in interests and sources“. Unlike the ''Tripartita'', the Decretum does not use any of the material in the ''Brugensis'' or ''Quadripartitus''. Furthermore, a form of the ''Britannica'' was used in which extracts from letters of pope Alexander II were present, in other words, a „better ''Britannica''“. Brett reveals that the Arsenal collection supplied long passages of texts for books 1, 4–5, 7–14 and 16 of the Decretum.
===Manuscript descriptions on this wiki===
For manuscripts, see [[:Category:Manuscript of ID]] (number of entries: {{PAGESINCATEGORY:Manuscript of ID}}).


As I have argued below (see p. 209 ff), I maintain that the Decretum was compiled well before 1110 because it was used for the ''Panormia'' of Ivo and that collection is at the basis of the first version of the ''Collectio X partium'' compiled at Thérouanne.
== Influence on other collections ==
The ''Decretum'' was used widely in northern France and England in the first half of the twelfth century, and copied well beyond that date. Several compilers took the massive ''Decretum'' as the starting point for their own, shorter collections. The most famous abbreviations of this kind are [[Collectio Tripartita#Tripartita B|part B of the ''Tripartita'']] and the extremely influential ''[[Panormia]]'' (which took additional material from the ''[[Collectio IV librorum]]'') Another short version is the Harly Abbreviation named after [[London, British Library, Harley 3090]].

There are three systematic collections associated with Bishop Ivo of Chartres: the Tripartita, the Decretum, and the Panormia. Only the Decretum can be linked with certainty to Ivo, who began to collect material when still at Saint-Quentin and had a mature version of the collection at hand in 1095.

Structure and content

The Decretum is one of the most comprehensive systematic collections of canon law of the Middle Ages. The material (approximately 3760 canons) is organised thematically into seventeen books of varying length. The first two books are devoted to the sacraments, followed by individual books, for example on the ecclesiastical hierarchy (Book 5), marriage law (Book 8) and a book ‘on lay matters’ (Book 16: De officiis laicorum); the last book is devoted to speculative theology. In general, canon law and theology are inseparable in Ivo's work; the Decretum contains an extraordinary amount of theological material (above all, from the writings of St Augustine).

Ivo wrote a prologue to the Decretum that is found with all copies of his collection but also a number of other collections; almost all Panormia copies, the Panormia-derivative Collectio X partium, one Tripartita copy, an abbreviation of Gratian's Decretum, and other works all begin with Ivo's prologue (which also was copied as part of his epistolary and enjoyed a separate circulation).

Formal sources

The Decretum contains almost all material found in the Liber decretorum of Burchard of Worms, and the division of the books is clearly inspired by Burchard. Ivo and his collaborators presumably used two different versions of the Liber decretorum; Chartres, BM, 161 is closely related to one of the copies they used. While Burchard's collection is comprehensive, it contributed only about half of the material that Ivo included in his own collection. The most important major sources are part A of the Tripartita and the Collectio Britannica. The first of the two so-called Arsenal collections is the best witness of the working materials Ivo and his team must have produced in the course of compiling the Decretum. It served as a preparatory collection to the Decretum in that it contained most non-Burchardian materials that ultimately were included in the Decretum. Another preparatory collection was a florilegium on the Eucharist Ivo had compiled when still canon at Saint-Quentin. Among the smaller sources, Ivo used Nicholas' Responsa perhaps from a manuscript related to Vat. lat. 3827, the collection of Chartres, BM, 193, and the Collectio canonum in Paris, BnF, lat. 13368.

Editions

The first edition was published by Jean van der Meulen (Molinaeus) in 1561 at Louvain. His edition was based on two copies, a „codex regius“ and a Cologne manuscript which no one has been able to identify. The surviving manuscript closest to the edition is Vat. Pal. lat. 587. Jean Fronteau published in Paris in 1647 a second, inferior edition as the first volume of the Opera omnia of Ivo. This second edition was reprinted in Migne PL 161. 47–1036. At present Martin Brett is preparing an edition he makes available at https://ivo-of-chartres.github.io/decretum.html

The Decretum in the Clavis Database

The present analysis (ID) is based on Paris, BnF, lat. 14315. Landau has established that the „French“ version was used in compiling Collectio B of the Tripartita, the Panormia, the Collectio S. Genoveve and a collection on fol. 314r–393v of the Ms Paris, BnF, lat. 4809.

Extant Manuscripts

Only a relatively small number of complete copies have survived, but as relatively many fragments make clear, the impact of Ivo's collection was wide and rapid; already in his lifetime, it was read, used, and copied well outside his diocese.

Sigla of the edition

The sigla for the major manuscripts in the following table are those of the edition by Martin Brett.

English vs. French manuscripts

Landau divided the surviving copies of the Decretum into a French (P and V) and an English group (C and R). As Brett has shown, P and V share many readings against C and R (and vice versa). There are also some texts found in group but not the other. While there is some evidence that the exemplars behind PV and CR were reworked independently (when eliminating doublets, they made different choices), the workshops producing these two versions were apparently in contact with each other (Rolker). An appendix of three folia at the end of the French Vat. lat. 1357 (fol. 244va–247rb), written in the main hand, contains the canons found in the „English“ copies.

Influence on other collections

The Decretum was used widely in northern France and England in the first half of the twelfth century, and copied well beyond that date. Several compilers took the massive Decretum as the starting point for their own, shorter collections. The most famous abbreviations of this kind are part B of the Tripartita and the extremely influential Panormia (which took additional material from the Collectio IV librorum) Another short version is the Harly Abbreviation named after London, British Library, Harley 3090.

Literature

For the manuscripts, the editions and the classification of the copies and some of the excerpts see Landau, Das Dekret, pp. 1–44; reprinted in his: Kanones und Dekretalen, pp. 117*–160* and 473*f. He also lists the canons peculiar to each version. For the manuscripts, the sources and the use of the Britannica see Brett, Urban II, pp. 41–44. – For the prologue see Bruce Brasington, The Prologue of Ivo of Chartres: A fresh consideration of the manuscripts, in : Proceedings of the 8th ICMCL, pp. 3–22. Idem, Studies in the Nachleben of Ivo of Chartres: The Influence of his Prologue on Several Panormia-Derivate Collections, in: Proceedings of the 9th ICMCL, pp. 63–85. –For the translation of the prologue into English, see Somerville and Brasington, Prefaces, pp. 132–158. Jean Werckmeister has published the Latin text, a translation into French together with an introduction: Yves de Chartres, Prologue, texte latin et traduction française (Sources canoniques 1, Paris 1997). See also from Werckmeister, Le premier „canoniste“: Yves de Chartres, RDC 47/1 (1997), pp. 53–70. – For the use of two copies of Burchard see Fowler-Magerl, Fine Distinctions, pp. 146–152. – For the papal decretals see Jasper, The Beginning of the Decretal Tradition, passim. Jasper has established the use of the Britannica for letters of popes Honorius (see p. 90 n. 5) and Leo IV (p. 109) and the use of both the Tripartita and the Britannica for some of the letters of pope Nicholas I (p. 124). Most of the letters of popes John VIII and Stephen V were also taken from the Britannica. For the letters of pope Leo I, see p. 57 n. 237, for the letters of pope John VIII, p. 129 f, for the letters of pope Stephen V, p. 131. – For the use of a synodal ordo taken from an Italian copy of the Liber decretorum of Burchard see Schneider, Die Konzilsordines, pp. 36 f [198] and 89. – For the excerpt in the Ms Lincoln see Paul Fournier, Notes sur les anciennes collections, RHD 12 (1933), pp. 130–132. – I would like to express my gratitude to Martin Brett who lent me his analyse of the excerpt in the Ms Antwerp, Musaeum Plantin-Moretus M. 144 and to Hans Van de Wouw who lent me his analyse of the Ms Leiden, BPL 184.
