The DEAF is a basic dictionary of Old French covering the period from 842 to the mid-14th century. The entries are arranged alphabetically by word families and are compiled according to strict philological principles (Ad fontes!). Further information can be found in our brief description. The project draws on the entire corpus of Old French literature, which is cataloged in the separately published Complément bibliographique. The publication appears online in DEAFél (DEAF électronique) as well as in print in installments of 192 columns. We leave the assessment of the work accomplished to others; here, we will content ourselves with presenting a few exemplary results that illustrate the encyclopedic aspects of the work.

Duration: 1984 to 2021

Why Old French?

Old French spans the period from 842 to the mid-14th century, an era that is fundamental to contemporary European history. Of central importance in this regard are, above all, the cultural and social transformations that took place in the context of the Renaissance of the 12th and 13th centuries: Building on ancient scholarship and enriched by Islamic and Jewish scholars, an Enlightenment spirit—initially taking shape in France—evolved into a form of scholarship critical of dogma, which spread throughout Europe and led to the birth of universities. It was here that the transition from a clerical culture to a lay culture—usually attributed to the age of Humanism—began. Developments in other areas of European culture during the 12th and 13th centuries can also be summarized under the term translatio studii from Greco-Roman antiquity to the French Middle Ages: The rapid development of the sciences finds parallels, for example, in the flourishing of vernacular literature and the emergence of chansons de geste, in the golden age of Romanesque art and the birth of the Gothic style, as well as in the revival of Roman law as the foundation of the European legal system.

The linguistic medium of the socio-cultural transformations described was, alongside Medieval Latin, above all Old French as the most influential vernacular language of the European Middle Ages. The number and geographical origin of the surviving sources give an impression of the historical significance of Old French: Its corpus comprises many thousands of texts originating not only from France but also from England, Cyprus, and the Holy Land, where French was the language of the ruling class for centuries. The prestige of Old French is also evident in an extensive Franco-Italian literary tradition—for example, the Venetian Marco Polo recounted his travels in Old French—and in its influence on alloglot literary traditions: Thus, the most important representatives of the Middle High German classical period (Wolfram von Eschenbach, Hartmann von Aue, and Gottfried von Straßburg) adapted French models in their romances. The commentaries by Rashi and his students from the 11th to the 13th centuries, which contain many thousands of Old French glosses, are still preserved today in all major Jewish editions of the Bible.

Historical lexicography makes a central contribution to research into the cultural foundations of Europe and thus to a better understanding of our present-day world by viewing vocabulary as the key to Europe’s cultural memory and thereby contributing to the holistic integration of historical and cultural knowledge. Given its central importance for the European Middle Ages, Old French appears particularly well-suited to serve as the linchpin of such a research approach. At the same time, the interdisciplinary nature of historical lexicography—understood as part of a comprehensive cultural studies—requires the integration of related philological disciplines—Medieval Latin, German studies, Semitic studies, Jewish studies, etc. —as well as the incorporation of historical studies, particularly disciplines focused on the history of ideas and social history, such as the history of science, the history of ideas, and the history of mentalities. By shedding light on the dynamics of language and extralinguistic culture in the context of the European Middle Ages, the historical lexicography of Old French can fulfill the goal of achieving a historically grounded understanding and evaluation of our contemporary world.
