Overview
In the first half of the 12th century
Gratian, ''clusinus episcopus'',
[Reali, Francesco (ed.), , 2009, pp. 63-73 and p. 244 has found and re-evaluated a Kalendarium of the Sienese Church owned by the Library of the Intronati of Siena (Ms FI2, f. 5v) in which, in Carolina minuscule writing with a date that at most can be placed in the mid-12th century, reads the following (after ): ; Reali observes that the text conforms to another reliable source of the 12th century, in which the author of the Decretum (who drafted the work in 1130) is referred to as (Robertus de Monte, Cronica, Bethman d. ''MGH Scriptores'' VI, Hanover 1844, p. 490) and that other sources of the twelfth and thirteenth centuries also speak of Gratian as bishop or as bishop of Chiusi.] probably a jurist of the ecclesiastical forum and a teacher, at the monastery of Saints Nabor and Felix (according to the Bolognese

Camaldolese monk,
[ composed the work he called , and others titled , or the more commonly accepted name, , a living text, characterized by multiple editorial stages. He did this to obviate the difficulties which beset the study and the forensic application of practical, external theology (), i.e., the study and the forensic use of canon law. In spite of its great reputation and wide diffusion, the has never been recognized by the Church as an official collection.
The so-called or vulgate version (an advanced editorial stage) of the is divided into three parts (, , ).
* The first part is divided into 101 distinctions (), the first 20 of which form an introduction to the general principles of canon law (); the remainder constitutes a , relative to ecclesiastical persons and function.
* The second part contains 36 causes (), divided into questions (), and treat of ecclesiastical administration, procedural issues and marriage. 3 of 33 on penance () is treated separately and subdivided into 7 distinctions.
* The third part deals with sacramental and liturgical law and contains 5 distinctions.
Each distinction or question contains , or maxims of Gratian, and . Gratian himself raises questions and brings forward difficulties, which he answers by quoting , i. e. canons of councils, decretals of the popes, texts of the Scripture or of the Fathers. These are the ; the entire remaining portion, even the summaries of the canons and the chronological indications, are called the maxims or .
Many have been inserted in the by authors of a later date. These are the , so called from Paucapalea, the name of the principal commentator on the . The Roman revisers of the 16th century (1566–1582) corrected the text of the "Decree" and added many critical notes designated by the words .

Citing the
The is cited by referring to the larger units of the distinction or the cause and question, and then the specific canon or dictum. For clarity, the distinctions of 33, 3 of the second part are referred to as (or ), while the distinctions of the third part are referred to as (or ). The Part is usually not included, as the citation form is different for each.
Citation styles for the have changed over time and can generally be categorised under the modern, obsolescent, and obsolete forms.
Modern form
This form, common since the twentieth century, cites all units in Arabic numerals, from largest unit to smallest unit.
Distinctions are referenced by an uppercase "D.", Causes by an uppercase "C.", questions by a lowercase "q.", and canons by a lowercase "c.". Gratian's are referred to with a lowercase "d. a. c." (, for commentary preceding the canon) or "d. p. c." (, for commentary following the canon).
Examples:
* art ID. 23 c.7
* art IIC. 15 q. 2 c. 4
* art IIC. 23 q. 8 d. p. c. 25
* art II, D. 3 de pen. c. 24
* art IIID. 2 de cons. c. 82
Obsolescent form
Commonly used between the seventeenth and early twentieth centuries, this form generally begins with a reference to the smallest unit in Arabic numerals, followed by the Distinction or Cause in Roman numerals and (if required) the question in Arabic numerals, e.g. "c. 5, C.3 q.1".
Obsolete form
This is the form used by medieval and early modern writers, falling out of use after the eighteenth century. Major divisions () were cited with (usually Roman) numerals. Since the numbering of the 's capitula only became standard in the sixteenth century, canons were cited by their opening word(s). Two or more canons beginning with the same word/phrase might be distinguished with numbers, e.g. .
Examples (using the same references as above):
*
*

Early commentators might also refer to the first few canons by number (e.g. for the third canon of a distinction), or to the last few canons as (, that is, third to last), (or or , second to last), and () or (last).

However, from the first editorial stages of the it is clear that Gratian had little knowledge of Roman law and that he had a great sense of depth in the disputes dealt with in the ecclesiastical seats, especially in the appeal judgments dealt with in the Roman curia.

) where Roman law was known and applied for years, it being plausible that he came from an episcopal city in which all jurisdiction, both civil and ecclesiastical, was dealt with by the only court present: the ecclesiastical one. Perhaps also for this reason he feels the need to create a legal work to be applied only in ecclesial courts and only for cases relating to canon law, putting an end to the mixture between civil and ecclesiastical jurisdictions. It is no coincidence that Dante Alighieri writes that he helped "one and the other forum", that is, he separated the canonical jurisdiction from the civil one.[Reali, Francesco, , in 30 (2020), 27–114] Gratian's work was an attempt, using early scholastic method, to reconcile seemingly contradictory canons from previous centuries.

Textual history
The vulgate version of Gratian's collection was completed at some point after the Second Council of the Lateran of 1139, which it quotes. Research by Anders Winroth established that some manuscripts of an early version of Gratian's text, which differs considerably from the mainstream textual tradition, have survived.
With later commentaries and supplements, the work was incorporated into the . The quickly became the standard textbook for students of canon law throughout Europe, but it never received any formal, official recognition by the papacy. Only the of 1917 put it out of use.[Crompton (2006):174]
As late as 1997, scholars commonly set the date of completion at 1140, but this accuracy in dating is not possible after Anders Winroth's groundbreaking scholarship. Winroth's research shows that the existed in two published recensions. The first dates to sometime after 1139, while the second dates to 1150 at the latest. There are several major differences between the two recensions:
*The first recension is a more coherent and analytical work.
*The second recension places a much greater emphasis on papal primacy and power.
*The second recension includes Roman law extracts taken directly from the , whereas the first recension does not demonstrate substantial familiarity with Roman jurisprudence.
These differences led Winroth to conclude that Roman law was not as far developed by 1140 as scholars had previously thought. He has also argued that the second recension was due not to the original author of the first recension (whom he calls Gratian 1), but rather another jurist versed in Roman law. However, Winroth's thesis of two Gratians remains controversial.
This field of inquiry is hampered by ignorance of the compiler's identity and the existence of manuscripts with abbreviated versions of the text or variant versions not represented by Winroth's two recensions. One of these is the manuscript St. Gall, , 673 (=Sg), which some have argued contains the earliest known draft (Larrainzar's ) of the , but which other scholars have argued contains an abbreviation of the first recension expanded with texts taken from the second recension.

Influence
Gratian himself named his work – "Concord of Discordant Canons". The name is fitting: Gratian tried to harmonize apparently contradictory canons with each other, by discussing different interpretations and deciding on a solution, as a judge in a case. This dialectical approach allowed for other law professors to work with the and to develop their own solutions and commentaries. These legists are known as the decretists.
These commentaries were called glosses. Editions printed in the 15th, 16th or 17th century frequently included the glosses along with the text. Collections of glosses were called "gloss apparatus" or (see also glossator). Systematic commentaries were called . Some of these were soon in circulation as well and obtained the same level of fame as the itself. Early commentators included Paucapalea and Magister Rolandus. The most important commentators were probably Rufin of Bologna (died before 1192) and Huguccio (died 1210). Less well-known was the commentary of Simon of Bisignano, which consisted of the ''Glosses on the '' and the .
Peter Lombard borrowed and adapted from the when discussing penance in his '' Sentences'' (c. 1150).[See Appendix B in Larson, ''Master of Penance''.]
Importance in Western law
Because of its influence as a source of canon law, the served as an influence for 12th-century jurists in the development of Western legal systems and their rules of evidence, which in canon law (including in the Decretum) did not include trial by ordeal and by battle.
The same author, Woods, called the "the first comprehensive and systematic legal treatise in the history of the West, and perhaps in the history of mankind – if by 'comprehensive' is meant the attempt to embrace virtually the entire law of a given polity, and if by 'systematic' is meant the express effort to codify that law as a single body, in which all parts are viewed as interacting to form a whole." The made a direct contribution to the development of Western law in areas that it dealt with such as marriage, property and inheritance. Specific concepts preferred included consent for marriage, and wrongful intent in determining whether a certain act constituted a crime. The Corpus Juris Civilis and Digesta were 'comprehensive' and preceded it, and so did the 'systematic' Institutes
