druid

druid, ancient religious leaders active in Ireland, Britain, and Gaul during the western European Iron Age. They existed from at least 200 bce and in some areas may have survived to about 400 ce. Although little is known with certainty about the druids, they probably constituted a predominantly or exclusively male priesthood that played an important role in the polytheistic religions of these Celtic-speaking societies. Much of what is known about the druids comes from Greek and Roman sources, which portray them as ritual specialists and community leaders who conducted sacrifices, performed divination, and served judicial and administrative functions. Despite limited concrete evidence of their beliefs and practices, druids have had a significant impact on modern culture.

Sources

Variants of the term druid were widespread in the Celtic languages; scholars have reconstructed the original Gaulish term as druis, although parallel terms appear in the medieval Irish druí, draoi, and drua. Pliny the Elder traced the term druid to the Greek word for oak; however, some recent scholarship argues that the term derived from ancient Indo-European language roots that mean “strong knowledge.” The word was absorbed into Latin as druides and entered modern English as druid. Although the term druid was used for religious specialists across Celtic-speaking areas, its connotations may have varied according to time and place—druids in Gaul during the 2nd century bce may have differed from those in Ireland during the 3rd century ce.

The druids left behind no surviving written accounts about themselves. Instead, historical evidence comes from classical and medieval sources, both of which modern historians regard with skepticism. Classical writers, including Julius Caesar, Cornelius Tacitus, and Pliny the Elder, mention the druids and their practices in writings that date from about 200 bce to 400 ce. Many of these writers never encountered druids firsthand, were sometimes informed only by hearsay or other secondary accounts, and in certain cases were motivated by a desire to justify Roman colonial expansion in the region.

The Roman general Julius Caesar is one of the most influential early writers on druids, and it is possible he encountered them in person. Caesar’s descriptions appear in his accounts of the conquest of Gaul, written in the 50s bce. He describes the leaders of society in Gaul as divided into two groups: the equites, or horsemen who may have functioned as warriors, and the druides, who were religious officials in charge of ritual sacrifices. Druids in Caesar’s account held important judicial functions, such as arbitrating disputes, and were excused from military service. He suggests that they were teachers who had training schools for new members, that they were unified under a single leader, and that they held annual meetings in central Gaul. Caesar also claims that druids conducted rituals involving burning alive human victims, typically criminals, inside large wicker figures. Modern historians generally view Caesar’s account with skepticism. Some contend that he projected onto druids the religious duties of Roman senators so as to make Gaulish society appear easy to integrate into Rome’s empire.

Other Classical-era writings often focus on druids’ ritual activities. Diodorus Siculus, writing in 36 bce, claims that druids divined the future by watching the flight of birds (augury), by examining the entrails of sacrifices (haruspicy), and sometimes by observing men’s death throes. Pliny the Elder, writing in the 1st century ce, asserts that druids assembled in oak groves, and he recounts a particular rite in which an officiating druid, clad in a white robe, used a golden sickle to cut mistletoe from an oak tree before performing sacrifices.

Medieval accounts of druids were composed by Christians during a period when the druids themselves were largely or totally extinct. Written principally in Ireland—and to a lesser extent Wales—these accounts usually frame druids as sorcerers who sometimes advised political leaders and who were in conflict with Christian missionaries. However, these medieval Irish and Welsh narratives about druids are often modeled on biblical accounts of wicked magicians such as Simon Magus, and their reliance on Christian literary tropes means that modern historians consider them unreliable as evidence about the pre-Christian druids.

Decline

The decline and disappearance of the druids is likely attributable to the dual impact of Roman imperialism and subsequent spread of Christianity. After the Romans invaded and occupied Gaul and southern Britain, records from the 1st century ce indicate that Roman authorities banned druids from territories under their control, perhaps motivated by concerns that the druids posed a political threat to imperial rule. Roman historian Tacitus recounts how a Roman army massacred a group of Britons, druids among them, at Mona (now Anglesey) off northwestern Wales in 59 or 60 ce. Although historians question Tacitus’s reliability, his report suggests that Roman attitudes toward druids could prove violent.

Roman rule never extended to the northern parts of Britain or to Ireland, and it is likely that druids in these regions survived for several additional centuries. However, from at least the 4th century ce Christianity spread across these areas, gradually supplanting the Iron Age religious traditions with which the druids were associated. In medieval Ireland, the term draideacht (“druidry”) became a synonym for the Christian concept of magic, and it served as a generic label for ritual and religious activities that Christian writers disapproved of. By the high Middle Ages, a time of Christian dominance across western Europe, it is likely that any accurate knowledge of the Iron Age druids had disappeared.

Legacy

In the early modern period, the ancient druids attracted the attention of antiquarians—scholars and collectors who studied ancient remains, manuscripts, and monuments. These antiquarian writers had a profound impact on wider popular perceptions of druids, but, like the Greek and Roman sources, they often came to unreliable conclusions. Conradus Celtis (1459–1508), a humanist scholar in Germany, portrayed druids as hooded and bearded philosophers, creating a visual image that still informs perceptions in the 21st century. Similarly influential were the English antiquarians John Aubrey (1626–97) and William Stukeley (1687–1765), who promoted the idea that druids built stone circles such as Stonehenge. Modern archaeologists, however, have established that stone circles long predate the Iron Age and find no evidence that druids used them as ritual centers.

Influenced by these antiquarian ideas, some people in the 18th century began to actively identify as druids themselves. Among the first to do so were members of certain British fraternal societies, the most notable of which was the Ancient Order of Druids (AOD) that formed in London in 1781. Similar fraternal druid orders later emerged in North America and Australasia. Members of these groups played on existing stereotypes by, for instance, dressing up in fake beards and white robes. The AOD organized a gathering at Stonehenge in 1905, furthering that monument’s association with druids in the popular imagination.

Drawing on the notion that the ancient druids were the forerunners of Wales’s medieval bards, certain Welsh cultural nationalists also started identifying as druids. A key figure in this process was the Welsh writer Edward Williams (1747–1826; known by his bardic name Iolo Morganwg), who gained attention for producing forgeries of what he claimed were medieval bardic texts. In 1861 the first Welsh National Eisteddfod—a formal assembly of Welsh bards—was held, continuing a history of regional eisteddfods, and subsequent Welsh bardic events incorporated senior figures who identified as druids.

From the 1910s several British esoteric groups also embraced druid identities, most notably the Universal Bond. This occult group began performing rituals at Stonehenge in 1912, and through this connection came to think of themselves as Druids. Their efforts produced modern Druidry, a new religious movement whose early practitioners often claimed to be continuing the practices of the ancient druids passed down in secret for two millenniums. By the 1990s many religious Druid groups were closely associated with modern Paganism, pursuing polytheistic traditions and performing rituals at prehistoric ceremonial sites such as Stonehenge and Avebury.

The ancient druids—and their depictions in classical and antiquarian scholarship—also exerted a strong influence on 20th- and 21st-century fantasy and historical fiction. A prominent example is the character Panoramix (in English translations, Getafix), the resident druid of a Gaulish village in the French comic series Asterix. Among Dungeons & Dragons role-players, druids are priests of nature, and in the video game World of Warcraft they have become shape-shifters. These fictional depictions of druids have further molded mainstream perceptions of these ancient religious figures about whom little is known conclusively.
