Medieval French literature is, for the purpose of this article, Medieval literature written in Oïl languages (particularly Old French and early Middle French) during the period from the eleventh century to the end of the fifteenth century.

The material and cultural conditions in France and associated territories around the year 1100 unleashed what the scholar Charles Homer Haskins termed the "Renaissance of the 12th century" and, for over the next hundred years, writers, "jongleurs", "clercs" and poets produced a profusion of remarkable creative works in all genres. Although the dynastic struggles of the Hundred Years' War and the Black Death pandemic of the fourteenth century in many ways curtailed this creative production, the fifteenth century laid the groundwork for the French Renaissance.

Language

Up to roughly 1340, the Romance languages spoken in the Middle Ages in the northern half of what is today France are collectively known as "ancien français" ("Old French") or "langues d'oïl" (languages where one says "oïl" to mean "yes"); following the Germanic invasions of France in the fifth century, these Northern dialects had developed distinctly different phonetic and syntactical structures from the languages spoken in southern France. The language in southern France is known as "langue d'oc" or the Occitan language family (a language where one says "oc" to mean "yes"), also known under the name of one of its dialects, the Provençal language. The Western peninsula of Brittany spoke Breton, a Celtic language. Catalan was spoken in the South, and Germanic languages and Franco-Provençal were spoken in the East.

The various dialects of Old French developed into what are recognised as regional languages today. Languages which developed from dialects of Old French include Bourguignon, Champenois, Franc-Comtois, Francien (theoretical), Gallo, Lorrain, Norman, Anglo-Norman (spoken in England after the Norman Conquest of 1066), Picard, Poitevin, Saintongeais and Walloon.

From 1340 to the beginning of the seventeenth century, a generalized French language became clearly distinguished from the other competing Oïl languages. This is referred to as Middle French ("moyen français").

The vast majority of literary production in Old French is in verse; the development of prose as a literary form was a late phenomenon (in the late Middle Ages, many of the romances and epics were converted into prose versions). The French language does not have a significant stress accent (like English) or long and short syllables (like Latin). This means that the French metric line is not determined by the number of beats, but by the number of syllables. The most common metric lengths are the ten-syllable line (decasyllable), the eight-syllable line (octosyllable) and the twelve-syllable line (the "alexandrine"). Verses could be combined in a variety of ways: blocks (of varying lengths) of assonanced (occasionally rhymed) lines are called "laisses"; another frequent form is the rhymed couplet. The choice of verse form was generally dictated by the genre. The Old French epics ("chansons de geste") are generally written in ten-syllable assonanced "laisses", while the chivalric romance ("roman") was usually written in octosyllabic rhymed couplets.

Early texts

The earliest extant French literary texts date from the ninth century, but very few texts before the eleventh century have survived. The first literary works written in Old French were saints' lives. The Canticle of Saint Eulalie, written in the second half of the ninth century, is generally accepted as the first such text. It is a short poem that recounts the martyrdom of a young girl.

The best known of the early Old French saints' lives is the Vie de saint Alexis, the life of Saint Alexis, a translation/rewriting of a Latin legend. Saint Alexis fled from his family's home in Rome on his wedding night and dwelled as a hermit in Syria until a mystical voice began telling people of his holiness. In order to avoid the earthly honor that came with such fame, he left Syria and was driven back to Rome, where he lived as a beggar at his family's house, unrecognized by all until his death. He was only identified later when the pope read his name in a letter held in the dead saint's hand. Although the saint left his family in order to devote his life more fully to God, the poem makes clear that his father, mother, and wife are saved by the Alexis' intercession and join him in Paradise. The earliest and best surviving text is in St. Albans Psalter, written probably at St Albans, England, in the second or third decade of the twelfth century. This provenance is indicative of the fact that many of the most important early texts were composed in Anglo-Norman dialect.

Genres Chansons de geste

At the beginning of the 13th century, Jean Bodel, in his Chanson de Saisnes, divided medieval French narrative literature into three subject areas: the Matter of France or Matter of Charlemagne the Matter of Rome – romances in an ancient setting (see roman below) the Matter of Britain – Arthurian romances, Breton lais (see roman below)

The first of these is the subject area of the chansons de geste ("songs of exploits" or "songs of (heroic) deeds"), epic poems typically composed in ten-syllable assonanced (occasionally rhymed) laisses. More than one hundred chansons de geste have survived in around three hundred manuscripts.La Chanson de Roland. Edited and Translated into Modern French by Ian Short. Paris: Livre de Poche, 1990. p. 12. The chief theme of the earliest French epics was the court of Charlemagne, Charles Martel and Charles the Bald and their wars against the Moors and Saracens, or disputes between kings and their rebellious vassals.

The oldest and most celebrated of the chansons de geste is The Song of Roland (earliest version composed ), seen by some as the national epic of France (comparable with Beowulf in England, the Song of the Nibelungs in Germany and the Lay of el Cid in Spain). It is perhaps no coincidence that the Song of Roland was first written down at a date very close to that of Pope Urban's call (1095) for the First Crusade; its plot may be seen as a glorification of the crusader ethos.

The earliest chansons de geste are (more or less) anonymous. They are popular literature (aimed at a warrior class, some say, though the evidence for this is inconclusive). They use an assortment of stock characters: the valiant hero, the brave traitor, the shifty or cowardly traitor, the Saracen, the giant, and so forth. But they also reveal much of the fears and conflicts that were part of the audience's experience. Kings are vain, foolish, old or wily. Insults that threaten honour or cause shame are seen to provoke bloody conflict, which may arise simply from competitiveness among knights or noble families. For discussion of the much debated origins of this epic genre, see Chanson de geste.

Approximately one hundred chansons survive, in manuscripts that date from the 12th to the 15th century. Not long after Jean Bodel (above), Bertrand de Bar-sur-Aube in his Girart de Vienne set out a grouping of the chansons de geste into three cycles, each named after a chief character or ancestral figure, and each with a central theme, such as loyalty to a feudal chief, or the defence of Christianity. This is a list of the cycles with a few of the chansons that belong to each: The Geste du roi. In these the chief character was Charlemagne or his heirs, and a pervasive theme was his role as the divine champion of Christianity. This cycle contains the earliest and best known of the epics – The Song of Roland ( for the Oxford text, the earliest version: several others exist, including an Occitan version) Fierabras () Aspremont (–1200) Huon de Bordeaux (–1268) Chanson de Saisnes by Jean Bodel (1200) The Geste de Garin de Monglane, whose central character was William of Orange. These dealt with knights who were typically younger sons without an inheritance who sought land and glory through combat with the Saracens. Chanson de Guillaume () Couronnement de Louis (1130) Charroi de Nîmes (1140) Prise d'Orange (1150?) Aliscans (1165) Aymeri de Narbonne and Girart de Vienne by Bertrand de Bar-sur-Aube (1190–1217) The Geste de Doon de Mayence (or the "rebel vassal cycle"); this cycle was concerned with rebels against (often unjust) royal authority and its most famous characters were Renaud de Montauban and Girart de Roussillon. Gormond et Isembart Girart de Roussillon (1160–1170) Renaud de Montauban or Les quatre fils Aymon (end of the 12th century) Raoul de Cambrai (end of the 12th century) Doön de Mayence (mid 13th century) A fourth grouping, not listed by Bertrand, is the Crusade cycle, dealing with the First Crusade and its immediate aftermath, and including: Chanson d'Antioche Les Chétifs Chanson de Jérusalem

New chansons tended to be produced and incorporated into the existing literature in two ways: A separate period or adventure in the life of an established hero was told (for example, his childhood). The adventures of one of the ancestors or descendants of an established hero was told. This method of epic expansion, with its obsession with blood line, was to be an important compositional technique throughout the Middle Ages. It also underscores the symbolic weight placed within this culture on family honor, paternal fidelity and on the idea of proving one's filial worth.

As the genre matured, it began to borrow elements from the French roman and the role of love became increasingly important. In some chansons de geste an element of self-parody appears, as in the Pèlerinage de Charlemagne.

Roman

Jean Bodel's other two categories—the "Matter of Rome" and the "Matter of Britain"—concern the French romance or "roman". The term "roman" signifies, roughly, "vernacular" (i.e. not Latin), but it is used to designate narrative poetry ("romance") usually written in octosyllabic rhymed couplets and telling stories of chivalry and love.

The most famous "romans" are those of the "Matter of Britain" dealing with Arthurian romance, the stories of Tristan and Iseult, the heroic legend of the doomed utopia of Camelot and the Holy Grail. Much of this material derives from Breton (Celtic) legends. The most important of these writers was Chrétien de Troyes (twelfth century).

The "Matter of Rome" concerns romances that take place in the ancient world, such as romances dealing with Alexander the Great, Troy, the Aeneid and Oedipus. Yet Bodel's category leaves little place for another important group of romances: those adventurous romances which are often set in Byzantium.

Sometimes linked with the "roman" are the Breton lais, narrative ballads of Britain by Marie de France, many of which have Celtic themes and origins.

Around a hundred verse romances survive from the period 1150–1220. Antoine Adam, Georges Lerminier, and Édouard Morot-Sir, eds. Littérature française. "Tome 1: Des origines à la fin du XVIIIe siècle," Paris: Larousse, 1967, p. 16. From around 1200 on, the tendency was increasingly to write the romances in prose (many of the earlier verse romances were adapted into prose versions), although new verse romances continued to be written to the end of the 14th century., Antoine Adam, Georges Lerminier, and Édouard Morot-Sir, eds. Littérature française. "Tome 1: Des origines à la fin du XVIIIe siècle," Paris: Larousse, 1967, p. 36-37. and it was chiefly in their prose form that many romances were read from the 14th to the 16th century.

The success of the early Arthurian romances also led, from around 1200 on, to a restructuring and compiling of the material into vast prose cycles. Antoine Adam, Georges Lerminier, and Édouard Morot-Sir, eds. Littérature française. "Tome 1: Des origines à la fin du XVIIIe siècle," Paris: Larousse, 1967, p. 36-37.
