Druidism

← Encyclopedia

Druidism names two things that are easy to confuse: the learned class of the pre-Roman Celtic peoples of Gaul and Britain, and the modern movement that, from the eighteenth century onward, revived the name and built a new practice around it. The two are joined by a word and very little else, and keeping them apart is the first task any account of the subject has to perform.

The Druids of antiquity

Of the ancient Druids almost nothing survives from their own hand. They left no writings — the classical notices agree that their teaching was committed to memory, not to script — so what is known descends through a small corpus authored entirely from the outside, by Greeks and Romans with reasons of their own. The longest single description is Caesar’s, in De Bello Gallico VI.13–20, written about 52 BCE in the course of a war of conquest. There the Druids appear as the learned order of Gaul: a class set apart from the warrior nobility, set over divine worship and the conduct of public and private sacrifice, the arbiters of nearly every dispute, the teachers of the young, exempt from war and tribute, organized under a single chief and gathering once a year at a consecrated place in the territory of the Carnutes. Caesar reports that they hold nothing in writing, that students sometimes remain in training for as long as twenty years, and that the order’s prestige rests in part on this very secrecy.

The doctrine Caesar singles out as central is one of the soul. The Druids teach, he says, that souls do not perish but pass after death from one body into another, and that this teaching kindles courage by stripping away the fear of death — a soldier who knows his soul will live again does not fight as a man with one life. The same belief recurs in the other notices. Diodorus Siculus, drawing (as Strabo also did) on the lost ethnography of Posidonius of Apamea, records that the Pythagorean conviction prevails among the Celts: that souls are immortal, and that after a set number of years they live again, the soul entering a second body. The comparison is the ancient world’s own. To a Greek or Roman observer the Druidic teaching on the soul looked like the doctrine already familiar from Pythagoras and the Pythagorean schools, and behind them from the Orphic poetry of reincarnation — the migration of the deathless soul through successive lives. Whether the resemblance reflects a genuine kinship of belief, a shared Indo-European inheritance, or simply the reflex of Mediterranean writers reaching for a category they already possessed cannot be settled from the sources. What it does establish is that the people who described the Druids placed them, at once, among the philosophers.

Alongside this learning the same writers report a darker register. Caesar describes human sacrifice, including the burning of victims in great figures of wickerwork; Strabo and Diodorus echo it; Tacitus, in the Annals, records the Roman destruction of the Druidic groves on the island of Anglesey in 60 or 61 CE, the priests cursing the legionaries from the shore. Pliny the Elder preserves the single most enduring image, the rite of oak and mistletoe in Natural History XVI: the mistletoe found growing on an oak, cut on an appointed day of the moon by a white-robed priest with a sickle of gold, caught in a white cloak, with two white bulls sacrificed beneath the tree. How much of all this is observation and how much the standard vocabulary for describing a conquered people as barbarous is a question that cannot be resolved from a record written by the conquerors. The Druids were a priestly class — the role belongs to the general history of the priest — and they practiced divination, reading omens and, in the hostile telling, the death-throes of victims. They were suppressed under Roman rule and their order did not survive the first century in any continuous form. What can be established with confidence is thin: such a class existed across Celtic Europe, it combined sacral, judicial, and educational authority, it held a doctrine of the soul’s survival, and every word about it comes from its enemies.

The long silence and its filling

Between the suppression of the order and the eighteenth century the Druids passed almost entirely out of view. They had left no scripture for a tradition to carry forward and no institution to carry it; the medieval West knew them, when it knew them at all, through the same handful of classical pages. The modern Druidism that bears the name is therefore not a survival but a reconstruction, and its history — because it is recent — can be told with a precision the ancient layer will never allow. It assembled itself in three strata, each governed by different evidence and producing different texts.

The first stratum is antiquarian. As the great megalithic monuments of southern Britain drew learned attention in the seventeenth and eighteenth centuries, the silence around their builders was filled with conjecture, and the Druids — the only pre-Roman priesthood the classical record named — were the natural candidates. John Aubrey first proposed, in manuscript, that Stonehenge and Avebury were pre-Roman British work and tentatively credited the Druids. William Stukeley made the connection canonical. His Stonehenge: A Temple Restor’d to the British Druids (London, 1740) and its companion Abury (1743) bound the stones to the Druids permanently in the British imagination. Stukeley’s plates and surveys remain valuable as fieldwork — he coined the term “trilithon” and recorded features since lost — but his interpretive frame was theology, not archaeology: he held that the Druids had practiced a primitive monotheism, a patriarchal religion descended through Abraham and the Phoenicians that prefigured Christianity, and that Stonehenge memorialized it. The thesis that Druids built Stonehenge has been untenable since stratigraphic excavation and radiocarbon dating: the monument’s principal phases fall roughly between 3000 and 1600 BCE, some two millennia before any people the sources would recognize as Druids. The “Druidic Stonehenge” is an eighteenth-century invention, and a durable one.

The second stratum is literary and Welsh. The Romantic age extended Stukeley’s overlay into a full Druidomania, from the prophetic books of William Blake, who set giant Druid temples in the mythic landscape of ancient Albion, to the speculative volumes of Edward Davies and Godfrey Higgins, the latter arguing that the Druids were emigrant Indian Brahmins. The decisive figure was Edward Williams, the Glamorgan stonemason and poet known as Iolo Morganwg. A forger of genius, he did not merely interpret the Druids; he invented an entire bardic-Druidic tradition and seeded it through Welsh letters. In 1792, on Primrose Hill in London, he convened the first Gorsedd of the Bards, a ceremony of his own design; he produced a forged “Third Series” of Welsh Triads, an invented bardic alphabet, a cyclical cosmology, and a body of doctrine that he claimed to have copied from old Glamorgan manuscripts and that scholarship has since shown he largely wrote himself. The Gorsedd was attached to the Carmarthen Eisteddfod in 1819 and became, from the mid-nineteenth century, a central institution of the National Eisteddfod of Wales — a living ceremony to this day. Its custodians no longer claim ancient descent: the National Library of Wales states plainly that Iolo devised the Gorsedd’s rituals from the Druids but gave them a strong Christian coloring, to assert that the heritage of the Celts belonged to the Welsh. It is a near-perfect specimen of what historians call an invented tradition — fabricated in its pedigree, wholly genuine as a cultural fact.

The third stratum is fraternal and, later, religious. The Ancient Order of Druids, founded in London in 1781 by Henry Hurle, was a benevolent society on the pattern of Freemasonry — lodges, regalia, and a Druidic dress rather than a Druidic creed; an 1833 split produced the friendly society known as the United Ancient Order of Druids. A separate lineage, the later Druid Order, traced itself to a meeting supposedly convened by John Toland at a Covent Garden tavern in 1717 — Toland did write a posthumously published history of the Druids — but that genealogy is a twentieth-century retrofit, modeled on the genuine 1717 founding of the Grand Lodge of England and built up around 1909 by George Watson MacGregor Reid. Out of these orders, and out of the wider occult and ceremonial-magical revival of the nineteenth and twentieth centuries, the modern nature-centered Druidry took shape: seasonal in its calendar, drawing on Celtic imagery, Romantic poetry, Iolo’s bardic cosmology, and the broader Western esoteric current. The Order of Bards, Ovates and Druids, founded in 1964, is the largest of these bodies. Practitioners hold a range of self-understandings, from those who frame the work as honoring an ancestral spirituality to those who treat it frankly as a modern creation worth keeping for its own sake — and the more reflective among them say so openly.

The scholarship and the texts

The study of the Druids is, to an unusual degree, the study of how the Druids have been imagined. The classical corpus that anchors everything is small and fully available: Caesar’s account in De Bello Gallico VI.13–20, hosted in the public-domain McDevitte and Bohn translation, can be read in full (Penelope/Thayer), and Pliny’s mistletoe rite from Natural History XVI is collected with its nineteenth-century translation in the survey of the ritual of oak and mistletoe. To these the standard ancient testimonies add Tacitus on Anglesey, Strabo’s fourth book, and Diodorus’s fifth — the last two preserving, at one remove, the lost Posidonian ethnography that stands behind much of the rest.

For the antiquarian layer the primary documents survive intact. Stukeley’s Stonehenge: A Temple Restor’d to the British Druids (1740) is freely readable (Project Gutenberg #61567) and is best approached as evidence for the eighteenth-century imagination rather than for the stones it claims to explain; its companion Abury (1743) survives in the same form. The Iolo Morganwg materials — the Myvyrian Archaiology of Wales (1801–1807), the posthumous Iolo Manuscripts (1848), and above all Barddas (edited by John Williams “Ab Ithel,” 1862 and 1874) — are likewise in the public domain, but they require a permanent caution: they are not records of ancient Druidic religion but the fullest articulation of a cosmology Iolo himself composed, and the National Library of Wales now describes them as such on the basis of more than a century of textual criticism, from Sir John Morris-Jones at the turn of the twentieth century through Griffith John Williams’s foundational studies of the 1920s and 1950s to the modern academic Welsh and Celtic studies project led by Geraint H. Jenkins (A Rattleskull Genius, 2005).

The controlling modern synthesis is Ronald Hutton’s Blood and Mistletoe: The History of the Druids in Britain (Yale University Press, 2009), with its shorter companion The Druids (2007). Hutton’s method is to make Druid scholarship itself the object of study, tracing how a priesthood about whom almost nothing certain can be said has been continuously remade across five centuries — as patriots, philosophers, proto-Christians, bloodthirsty pagans, or Indian sages — according to the needs of each generation. For the historical order, Stuart Piggott’s The Druids (Thames and Hudson, 1968) remains a lucid bridge: his distinction among the Druids as known, as inferred, and as wished-for anticipated the reception-historical turn by decades, and his earlier monograph on Stukeley established that the antiquary’s Druids were a function of his theology. T. D. Kendrick’s older The Druids (1927) is valuable chiefly for assembling the entire classical corpus in one place. The line of inquiry these works define is not “what did the Druids believe?” — a question the evidence forbids — but “whose Druids are these, written by whom, for what purpose, and under what rules of proof?”

The two Druidisms

Between the two Druidisms lies a gap that scholarship insists on and the revival has often wished away. There is no demonstrable line of transmission from the ancient priesthood to the modern orders; the continuity is one of name and aspiration, not of inheritance. That does not make the modern movement unserious — a tradition can be young and still be meant, and Iolo’s Gorsedd, for all that it was conjured from forgery, is now a genuine fixture of Welsh life. But the documentary record offers no bridge across the centuries when the original class was gone, and the revived practice is, on the evidence, a reconstruction reaching back toward a figure it can know only at second hand.
