WOAD, TATTOOING AND IDENTITY IN LATER IRON AGE
AND EARLY ROMAN BRITAIN
Summary. This paper explores the archaeological evidence for the practice
of facial and corporeal dyeing, painting and tattooing in the later Iron Age and
early Roman period. The aim is to construct a hypothesis which explains how,
why, when and by whom such pigments were worn. Although this hypothesis
discusses woad-derived indigo, this is used mainly, although not exclusively,
as an experimental tool, as no conclusive archaeological evidence exists which
reveals the identity of the ‘real’ pigment(s). Woad has also long held a place
in the popular imagination as the source of the dye which the ancient Britons
used to paint themselves.
This paper explores the possibility that the cosmetic grinder was the
focal artefact used in body painting or tattooing, and was used for grinding
and mixing body and face paint. It is suggested that, rather than being a
‘Roman’-style tool for cosmetic application from the start, it may have begun
life as an artefact first used by the later Iron Age Britons for body painting and
expressing indigenous identities.
INTRODUCTION
Described variously as pendant charms deriving their shape from the iron nose-bands
used for horses (Smith 1918); grooved pendants (Trett 1983); and a device used for grinding up
medicaments or cosmetics (Jackson 1985, 1993, forthcoming; Jackson and Thullier 1999; Stead
and Rigby 1989), the cosmetic grinder is a small cast-bronze crescent-shaped object consisting,
when complete, of two parts: a pestle and mortar. They date from the first century AD to the
fifth century AD (although Jackson (1993, 167) states that there is no doubt that the type is
Romano-British with its origins in the later Iron Age), and occur predominantly in the first and
second centuries AD (Jackson 1985, 175). Cosmetic grinders range between 5–11 cm in length
(Jackson 1985, 168). Although the pestles are generally plain, the mortars are decorated with
either knobbed, zoomorphic, phallic or plain terminals. The type is exclusive to Britain, most
commonly found in the south-east (Jackson 1985, 172); more recently, however, two examples
have turned up in northern France, assumed either to have been traded from Britain or buried
with a British immigrant (Jackson and Thullier 1999, 23–4).
Jackson interpreted the cosmetic grinder as an artefact used for grinding minerals for
eye and face paints for the ‘Roman’-style practice of cosmetic application despite the fact that
they are made in a non-Classical style and did not originate in the Roman world. His research

showed that although their associations were with ‘less Romanised’ settlements, temple and
grave contexts (Jackson 1985, 172), there was no single or restricted sphere of use. Explored
here is the idea that they were initially used for a more native practice – that they were part of
the paraphernalia used in the application of woad-derived indigo.
Five observations suggest that cosmetic grinders were predominantly a non-‘Roman’
artefact used for a purpose that pre-dates the Roman period:
1. Cosmetic grinders are found only in Britain and nowhere else in the Roman world (bar the
two recent examples from Gaul).
2. Romans had their own tool for grinding cosmetics: the stone palette, many examples of
which are found in Britain.
3. Cosmetic grinders are made in a variety of styles such that no two are alike (although sub-
types have now been identified). This is not a feature of Roman bronzes (Jackson 1985,
169).
4. Cosmetic grinders are made in a native Romano-British and not a Classical style (Jackson
1985, 168 and 170).
5. A ‘handful’ of cosmetic grinders date to before the Conquest (Jackson forthcoming and pers.
comm.)
This ‘handful’ includes grinders from King Harry Lane, Hunsbury, Gussage All Saints,
Hod Hill and Hockwold (Jackson 1985, nos. 1, 33, 59, 50–1). An example from Normanton le
Heath in Leicestershire has also been published (Thorpe, Sharman and Clay 1994, 49) that
‘suggests a late Iron Age origin for these sets’. Jackson warns us that the great majority are
found by metal detectorists and are, consequently, without context.
With an indigenous later Iron Age origin for the cosmetic grinder thus established, it is
now necessary to consider how these objects were used.
THE METHOD OF WOAD PROCESSING
Although Hobbs (2003, 109) asserts that cosmetic grinders were not used to process
woad because it was a vegetable dye (and thus a liquid), he neglects to consider the pigment
indigo, which can be extracted from woad ( Isatis tinctoria ) plants. It would have been relatively
straightforward for people of the Iron Age to extract indigo from woad for tattooing. The only
ingredients needed were woad plants, water, and ammonia (perhaps in the form of stale urine).
Buchanan (1987) outlines the simple recipe as follows:
1. Chop woad plants.
2. Boil in water and leave to steep for an hour.
3. Strain liquid and keep, but throw plant matter away.
4. Add ammonia to the liquid until it reaches pH 9 or above.
5. Stir liquid in air for 10–15 minutes until blue particles appear on top.
6. Let particles settle for an hour or more and decant, leaving the sediment (or indigo) to dry
out.
7. Powder the indigo for further use.
The cosmetic grinder would have been used in the final stages of woad processing to
grind up the dried product. The woad-derived indigo would then have been in a form suitable
for use in either tattooing or body painting. The yield from woad is small (Plowright (1900)

reports that half a kilogramme of one-month-old woad plants yields 2.4 g of impure indigo), and
thus consistent with the small amount of powder with which the pestle and mortar can cope.
It is suggested that the design of the cosmetic grinder and the decoration of the mortar
terminals relate not only to the recipe needed to extract indigo from woad, but especially to the
agent needed to bind the pigment to the body. The terminal designs include bovine and duck

heads (the binding agent in these cases being milk or egg whites, or perhaps the fats and juices
from cooking beef or duck); and also phallic designs (the binding agent being semen). The
phallic design also reflects a constituent of the recipe, i.e. ammonia, in the form of urine. A
binding agent of fat is an important consideration if the Britons, like the Gauls, went into battle
naked, as recorded by Diodorus Siculus (V, 29–30). This would have kept them insulated against
the cold.
As well as a tool for powdering woad-derived indigo, the cosmetic grinder was probably
also used as a mixing trough for the powder and binding agent (experimental work by the author
has shown that thorough mixing is required to produce a good pigment). The pointed end of the
pestle could then have been used for drawing delicate designs on the wearer, which could then
have been pricked into the skin to make tattoos, or merely left as body paint. Trett (1983)
remarked that the tip of the pestle from King Harry Lane was quite worn, suggesting that this
part of the pestle had been used for thorough grinding; Jackson (1993, 165) has also observed
wear marks on many pestles and mortars. Alternatively, the length of the pestle could have been
used to smear the mixture onto the body. The use of the cosmetic grinder, rather than fingers,
for grinding, mixing and painting emphasizes the special, magical properties which woad-
derived indigo was perceived to possess (as discussed below). At no stage did the body
paint/tattoo specialist need to ‘contaminate’ his or her skin with this powerful pigment or waste
valuable indigo powder by getting it on his or her hands.
Experiments by the author have shown that a very small amount of indigo powder (the
area of half a little-finger nail) goes a very long way when mixed with approximately a dessert-
spoonful of the binding agent: enough to block-cover a couple of limbs. However, given the
small capacity of the cosmetic grinder, perhaps intricate designs rather than block cover were
more important.
In the experiment outlined below, indigo powder was mixed with beef dripping, milk,
water, egg yolk, egg white and semen and examined for the ease with which it mixed with the
powder, the consistency of the mixture, the colour of the mixture when dry, and the ease with
which it was removed.

These binding agents produce a variety of colours from steely grey-blue, through
intense midnight blue, to black, something which varied with amount of indigo used and colour
of skin. Most effective as a body paint was the beef dripping, which cools to a consistency of
shoe-polish suggesting that, as it does not dry, it could be saved until it was next needed, unlike
the other binding agents. Some of the colours yielded were similar to those used in military
camouflage palettes. Although the modern soldier’s aim is to break up the face, make it appear
two-dimensional and obscure the outline, some colours, such as the steel blue-grey produced
by mixing indigo and beef dripping, would render the face almost invisible in certain lighting
conditions (Lt. Patrick Larkin, pers. comm.). Because indigo produces a range of light and dark
blue, black and grey colours when mixed with different binding agents, we can imagine that the
native Britons would have had a choice of colours from which to choose, depending on the
occasion (such as battle or ritual ceremony), time of day, year, or weather conditions.
There are other ways in which the native Britons could have used the woad plant to
turn themselves entirely blue, rather than making indigo for tattooing or body painting. They
could either have produced enough indigo to paint the entire body, a time-consuming business,
or they could have set up a woad vat, bath or cauldron into which a person could climb. Residue
analysis of such vessels as cauldrons is long overdue; where the procedure has been applied,
the results have been most interesting, e.g. the discovery of mead in the cauldron at Hochdorf
(Körber-Grohne 1980, 250, 1985, 121–2).
Although we do not know how the woad vat would have been set up in the Iron Age,
evidence for the medieval method has survived and has been outlined by Hurry (1930). The aim
of the woad vat was to produce a reduction reaction, which could reduce the oxidized and
insoluble blue indigo into a soluble white form, which turns blue on exposure to air. Only in
the soluble form can it bind with the protein in the skin. These bonds prevent the indigo from
being washed off skin and, indeed, fabric dyed with indigo. It should be noted that indigo powder
in the insoluble (but miscible), oxidized form will wash off, as it has not bonded with the protein
in the skin.
A person dipped into the woad vat at this stage would then be dyed blue. However, on
first emerging from the woad vat, the person would be a dirty brown colour because of the contents
of the mixture. They would only turn blue after re-oxidation, which takes a few minutes. The
spontaneous change of colour after a few minutes would have seemed a magical process to the
Britons, and would have added to the perception of woad as a magical plant. In the discussion of
fabric dyeing, Plowright (1901–2) noted that fabric turned varying shades of blue, green or grey
depending on which alkaline agents were added and depending on the length or number of times
they were dipped into the woad vat. We can assume that the results would be similar for skin.
ARCHAEOLOGICAL EVIDENCE FOR TATTOOING AND BODY PAINTING
What evidence do we have that tattooing and body painting using indigo or any other
substance took place? There are five main sources of data:
1. Classical authors.
2. Traces of pigments or plant matter used for body painting or tattooing.
3. Bog bodies such as Lindow Man that may have traces of pigments on the skin.
4. Coin evidence for facial tattoos.
5. Paraphernalia for woad processing.
