The idea of the Middle Ages
The term and concept before the 18th century
From the 4th to the 15th century, writers of history thought within a linear framework of time derived from the Christian understanding of Scripture—the sequence of Creation, Incarnation, Christ’s Second Coming, and the Last Judgment. In Book XXII of City of God, the great Church Father Augustine of Hippo (354–430) posited six ages of world history, which paralleled the six days of Creation and the six ages of the individual human life span. For Augustine, the six ages of history—from Adam and Eve to the Flood, from the Flood to Abraham, from Abraham to King David, from David to the Babylonian Exile, from the Exile to Jesus Christ, and from Christ to the Second Coming—would be followed by a seventh age, the reign of Christ on earth. World history was conceived as “salvation history”—the course of events from Creation to the Last Judgment—and its purposes were religious and moral. Thus, all the references by Augustine and other early authors to a “middle time” must be understood within the framework of the sixth age of salvation history. Early Christian interpretations of the biblical Book of Daniel (Daniel 2:31–45, 7), especially those of the Church Father Jerome (c. 347–419/420) and the historian Paulus Orosius (flourished 414–417), added the idea of four successive world empires—Babylon, Persia, Greece, and Rome. Late writers in this tradition added the idea of the translation imperii (“translation of empire”): from Alexander the Great to the Romans, from the Romans to the Franks under Charlemagne in 800, and from Charlemagne to the East Frankish emperors and Otto I. A number of early European thinkers built upon the idea of the translation of empire to define European civilization in terms of scholarship and chivalry (the knightly code of conduct). All these ideas were readily compatible with the Augustinian sequence of the six ages of the world.
The single exception to this trend was the work of the late 12th-century Calabrian abbot and scriptural exegete Joachim of Fiore (c. 1130– c. 1201). According to Joachim, there were three ages in human history: that of the Father (before Christ), that of the Son (from Christ to an unknown future date, which some of Joachim’s followers located in the late 13th century), and that of the Holy Spirit (during which all Christendom would turn into a vast church with a universal priesthood of believers). But Joachim’s view was also firmly expressed in terms of salvation history. Many chroniclers and writers of histories, of course, wrote about shorter periods of time and focused their efforts on local affairs, but the great Augustinian metanarrative underlay their work too. From several confessional perspectives, this view still survives.
In the 14th century, however, the literary moralist Petrarch (1304–74), fascinated with ancient Roman history and contemptuous of the time that followed it, including his own century, divided the past into ancient and new—antiquity and recent times—and located the transition between them in the 4th century, when the Roman emperors converted to Christianity. According to Petrarch, what followed was an age of tenebrae (“shadows”), a “sordid middle time” with only the hope of a better age to follow. Although Petrarch’s disapproval of the Christianized Roman and post-Roman world may seem irreligious, he was in fact a devout Christian; his judgment was based on aesthetic, moral, and philological criteria, not Christian ones. Petrarch’s limitless admiration for Rome heralded a novel conception of the European past and established criteria for historical periodization other than those of salvation history or the history of the church, empire, cities, rulers, or noble dynasties. His followers in later centuries focused primarily on the transformation of the arts and letters, seeing a renewal of earlier Roman dignity and achievement beginning with the painter Giotto (1266/67 or 1276–1337) and with Petrarch himself and continuing into the 15th and 16th centuries.
In the early 16th century, religious critics and reformers, including both the Dutch humanist Desiderius Erasmus and the Protestant reformer Martin Luther, added another dimension to the new conception and terminology: the idea of an evangelical, apostolic Christian church that had become corrupt when it was absorbed by the Roman Empire and now needed to be reformed, or restored to its earlier apostolic authenticity. The idea of reform had long been built into the Christian worldview. This conception of the period between the 4th and 16th centuries was laid out in the great Protestant history by Matthias Flacius Illyricus, Centuriae Magdeburgensis (1559–74; “The Magdeburg Centuries”), which also introduced the practice of dividing the past into ostensibly neutral centuries. The Roman Catholic version of church history was reflected in the Annales Ecclesiastici (“Ecclesiastical Annals”) of Caesar Baronius (1538–1607), completed by Oderico Rinaldi in 1677. Thus, the historical dimension of both the Protestant and the Catholic reformations of the 16th and 17th centuries added a sharply polemical religious interpretation of the Christian past to Petrarch’s original conception, as church history was put to the service of confessional debate.
Petrarch’s cultural successors, the literary humanists, also used variants of the expression Middle Ages. Among them was media tempestas (“middle time”), first used by Giovanni Andrea, bishop of Aleria, in 1469; others were media antiquitas (“middle antiquity”), media aetas (“middle era”), and media tempora (“middle times”), all first used between 1514 and 1530. The political theorist and historian Melchior Goldast appears to have coined the variation medium aevum (“a middle age”) in 1604; shortly after, in a Latin work of 1610, the English jurist and legal historian John Selden repeated medium aevum, Anglicizing the term in 1614 to middle times and in 1618 to middle ages. In 1641 the French historian Pierre de Marca apparently coined the French vernacular term le moyen âge, which gained authority in the respected lexicographical work Glossarium ad scriptores mediae et infimae latinitatis (1678; “A Glossary for Writers of Middle and Low Latin”), by Charles du Fresne, seigneur du Cange, who emphasized the inferior and “middle” quality of Latin linguistic usage after the 4th century. Other 17th-century historians, including Gisbertus Voetius and Georg Horn, used terms such as media aetas in their histories of the church before the Reformation of the 16th century.
The term and idea circulated even more widely in other historical works. Du Cange’s great dictionary also used the Latin term medium aevum, as did the popular historical textbook The Nucleus of Middle History Between Ancient and Modern (1688), by the German historian Christoph Keller—although Keller observed that in naming the period he was simply following the terminology of earlier and contemporary scholars. By the late 17th century the most commonly used term for the period in Latin was medium aevum, and various equivalents of Middle Ages or Middle Age were used in European vernacular languages.
