The hair of the ancient Celts has been remarked upon, depicted, and satirized for more than two thousand years, and the sight of long-haired, mustachioed Celtic warriors became one of the most enduring images in the visual vocabulary of the classical world. To examine how the ancient Celts styled their hair is to enter a world in which hair was never a trivial matter, in which the length, the color, the arrangement, and even the cutting of a person’s hair could carry religious, social, and political meaning, and in which the warrior class in particular made its hair a defining feature of its public identity. As part of the wider world of Celtic clothing and adornment, the styling of Celtic hair striking features of the broader Celtic culture and daily life.
The Classical Stereotype
The Greek and Roman writers who encountered the Celts from the fourth century BCE onward were almost unanimous in their attention to Celtic hair. They were equally unanimous in finding it remarkable, by Mediterranean standards at least, for its length, its color, and the way in which it was treated. Diodorus Siculus, in the first century BCE, wrote that the Gauls wore their hair long and washed it repeatedly, and that the wealthier among them used a kind of pomade or hair-treatment that was said to make the hair thick and lustrous. The Greek writer Posidonius, whose lost work on the Celts was the principal source for later Greek and Roman accounts, several times described the long hair of the Celtic warriors, and his description was passed on, with variations, by Strabo, Athenaeus, and others.
The Roman stereotype of the long-haired Gaul was established early and persisted for centuries. Roman writers repeatedly contrast the long, flowing hair of the Celtic warrior with the close-cropped hair of the Roman legionary, and the image of the wild-haired, mustachioed barbarian became a stock feature of Roman triumphal art. The coinage minted by Roman commanders to celebrate their victories over the Gauls often showed defeated Celtic warriors with their distinctive long hair, and the image of the Roman general capturing a Gaul by the hair became a standard triumphal motif. The stereotype was not entirely fair to the variety of hairstyles practiced in the Celtic world, but it captured a real feature of Celtic self-presentation, and the Romans were quick to recognize the political and military significance of the long-haired warrior.
Lime-Washing and the Color of Celtic Hair
The most striking feature of Celtic hair, to Mediterranean eyes at least, was its color. The Celts of the Iron Age were, by the testimony of the classical writers, given to washing or treating their hair with a kind of alkaline solution that lightened it, often to a shade that the Greek and Roman writers variously described as reddish, golden, or even whitish. The treatment was produced by steeping the hair in a solution of potash or slaked lime, and the effect was a kind of artificial bleaching. The process is mentioned by several classical writers, including Diodorus Siculus, who described it in some detail.
The archaeological and pictorial evidence confirms the practice. Celtic coins, particularly those of the late Iron Age, often show warriors with long, light-colored hair, and the famous Roman-era statues of defeated Gauls, particularly the so-called dying Gaul of the Pergamene school, show warriors with long, light hair that has clearly been treated in this way. The treatment was a status marker, a deliberate transformation of the natural hair into a color that signified membership in the warrior elite, and it was clearly practiced widely enough to become a recognizable feature of Celtic appearance. The early medieval Irish sources preserve a memory of the practice, and the descriptions of golden-haired warriors and heroes in the Irish tales, including the famous description of Cú Chulainn’s hair, with its three colors of dark, red, and gold, can plausibly be read as a literary echo of the older practice of artificial lightening.
Hair Length and the Warrior Class
The length of a Celtic warrior’s hair was a direct indication of his rank, his status, and his place in the social order. Diodorus Siculus describes how the Celtic warriors wore their hair long in time of peace, in order to enhance their height and to appear more impressive in the eyes of their enemies, and how they tied it back with a golden clasp or pin in time of war, in order to keep it out of their eyes during battle. The contrast between the loose hair of peacetime and the tied-back hair of war striking features of Celtic self-presentation, and the gold or bronze pin that secured the hair in battle, often a finely crafted object in its own right, was another marker of status.
The cutting of the hair, in this context, was an act of enormous social significance. A haircut was a sign of disgrace, of ritual change of status, or of mourning. Caesar, in his account of the Gallic campaigns, describes how the defeated Bituriges were forced to cut their hair as a sign of submission, and the early Irish law texts specify that a person who had been subjected to ritual censure, or who had been excommunicated from his kin group, was to be shaved as a sign of his changed status. The growth of the hair, conversely, marked the transition from boyhood to manhood, and the cutting of the hair by a young man, often in a religious context, marked his entry into the adult world.
Beards, Moustaches, and the Male Face
The moustache, in particular, was a defining feature of the Celtic male warrior, and the careful cultivation of a long, often drooping moustache was a distinctive feature of the Celtic warrior class. The classical writers remark on the moustaches of the Celtic warriors repeatedly, and the Roman stereotype of the long-haired, mustachioed Gaul was based on this real feature of Celtic appearance. The moustache, like the long hair, was a sign of adulthood and of warrior status, and the loss of the moustache through shaving, like the loss of the hair, was a sign of disgrace or ritual change of status.
The beard, worn longer or shorter depending on the fashion of the time, was a common feature of Celtic male appearance, and the combination of long hair, moustache, and beard was the standard look of the Celtic warrior. The early medieval Irish sources preserve descriptions of the heroic warrior with his long hair and his carefully groomed moustache, and the descriptions of Cú Chulainn in the Táin Bó Cúailnge, with his mane of dark hair and his long moustache, are clearly descended from the older Iron Age tradition. The Pictish tradition of facial decoration, including the body painting and possibly tattooing for which the Picts are named, is another indication of the importance attached to the presentation of the male body in the Celtic world.
Women’s Hair and Female Adornment
The hair of Celtic women was as carefully styled as the hair of Celtic men, and the literary and archaeological evidence suggests that the elaborate dressing of female hair was a central feature of female appearance. The classical writers are less forthcoming about Celtic women’s hair than about men’s, but the early medieval Irish and Welsh sources provide a rich picture of the hairstyles of noble and royal women. The long hair worn loose, in braids, in plaits, in buns, and in elaborate arrangements decorated with hairpins, ribbons, and metal ornaments is a recurring feature of the descriptions of noble women in the Irish and Welsh tales.
The brooches and hairpins used to secure and decorate women’s hair were among the most elaborate of all Celtic personal ornaments. The hairpins of late Iron Age Britain and continental Europe, often made of bone, bronze, or silver, were frequently decorated with intricate patterns and sometimes with figures of gods or animals. The early medieval Irish and Scottish hairpins, often of silver and decorated with interlaced patterns, were similarly elaborate, and the surviving examples from sites like the Hunterston Brooch deposit and the Tara Brooch deposit demonstrate the technical sophistication of Celtic metalwork in this tradition. The female head, in the Celtic world, was a public space, a place where status and identity could be displayed, and the careful dressing of a noble woman’s hair was an important part of the public presentation of her rank and her kin group.
Hair and Social Meaning
The social meaning of hair in the Celtic world extended well beyond the warrior class. The early Irish law texts devote considerable attention to the regulation of hair, specifying the kinds of hairstyles appropriate to men and women of different ranks, the occasions on which particular styles could be worn, and the penalties for wearing the wrong kind of hairstyle for one’s station. The captive, the exile, the criminal, and the person in mourning were all marked by particular styles of hair, and the ways in which the hair could be cut, tied, decorated, or concealed were carefully regulated by custom and law.
The religious meaning of hair was equally strong. The early Irish saints’ lives are full of references to monks and nuns who cut their hair as a sign of their entry into religious life, and the tonsure of the early Celtic church, in which the front of the head was shaved and the back was left long, was a distinctive feature of Celtic monastic practice. The Celtic tonsure, which was the subject of considerable controversy between the Celtic churches and Rome, was probably a Christian adaptation of older pre-Christian practices, and the survival of older associations between the length of the hair and the religious or social status of the wearer distinctive features of the Christian conversion of the Celtic-speaking regions.
The Survival of Celtic Hair Traditions
The long, light-colored, carefully groomed hair of the ancient Celts did not survive the Roman conquest in most of the continental Celtic-speaking regions, but it persisted in the non-Romanized Celtic-speaking regions of Britain, Ireland, and Scotland. The early medieval Irish and Welsh sources preserve a vivid picture of the long-haired warriors and the elaborately dressed noble women of the older tradition, and the descriptions of heroes like Cú Chulainn, Fionn mac Cumhaill, and the warriors of the Fenian cycle reflect older conventions of masculine appearance that go back to the Iron Age.
The medieval and early modern survival of the long hair tradition in the Celtic-speaking regions, particularly in Scotland and Ireland, was strong enough to attract the attention of English writers, who repeatedly commented on the long hair of the Highlanders and the Irish. The eventual suppression of the long-haired tradition in the eighteenth and nineteenth centuries, particularly after the Battle of Culloden in 1746, was a deliberate act of cultural suppression aimed at the Gaelic-speaking peoples of the Highlands and Islands, and the long hair of the Highlander became, in the romantic imagination of the later eighteenth and nineteenth centuries, a symbol of the lost Celtic past. The tradition, in some form, has been preserved into the present, and the long hair of certain traditional musicians, dancers, and Gaelic speakers is a living echo of one of the most distinctive features of ancient Celtic appearance.
