IntroductionThis booklet, which owes its origins to a series ofnotes first published in Lithics (Martingell 1980, 981,1982, and 1983), is intended to serve as a guide to theillustration of lithic artefacts. It is restricted in focusto types of prehistoric flint and stone tools commonlyfound in Britain, though many of the principlesinvolved will have a much wider application. Thebooklet is aimed primarily at illustrators who are notthemselves lithic specialists but who are in the positionof preparing drawings to accompany specialist lithicreports for publication in archaeological journals andbooks. Such a guidebook seems necessary because therecent growth of interest in lithic studies is leading toan increase in the amount of lithic illustration beingundertaken by more and more illustrators. At thesame time the development of specialist knowledge inthe field of lithics is making greater demands on theillustrator to record ever more detail, often by the useof special conventions and symbols. The experiencedlithic illustrator mayf ind little herein that is new, butit is hoped that the novice illustrator, or the practisingillustrator turning to flint and stone artefacts for thefirst time, will be helped by the following pointsand guidelines. This booklet is also aimed at lithicspecialists themselves, and at non-specialist excavatorsand editors who may be involved in the commissioningof, and in overseeing the publication of, lithic reports.Flint and stone artefacts are usually illustrated in astyle that gives a three-dimensional impression, aform of representation which supplies the maximumamount of information about the technology of anartefact in each single drawing. While the authorswould advocate and seek to encourage the highestpossible standard of illustration, it must be admittedthat the very best examples of the almost fully ‘lifelike’three-dimensional style – for example as achieved inthe woodcut engravings by Swain (in Evans 1897), orin pen-and-ink by Dauvois (1976) – involve a degreeof artistry and commitment which may be beyond theaverage illustrator or at least not cost-effective withinpost-excavation budgets. Constraints on budgetsmay even require at times the production of ‘open’drawings without infilling the details of flake scars.Nevertheless, whatever the style, it is necessary toemphasize the overriding need for accuracy in this asin other aspects of archaeological drawing. A groupof superficially similar implements, such as a seriesof leaf-shaped arrowheads from the same site, willcontain differences of detail which the specialist willneed to see reflected in the illustrations, and whichwill be necessary to enable the reader to comprehendvisually the specialist’s written account. Researchworkers and museum staff will require accurateillustrations to check against the artefacts themselvesor against catalogue notes; all too often either theartefacts or the original records can become mislaid,and then the illustrations are vital in re-establishinga provenance or re-uniting an assemblage. Ideally,illustrations should be an essential part of a catalogueof lithic artefacts, though in this case not all drawingswill necessarily be finished to publication standard.Consistencies of style, of orientation (Fig. 1), ofconventions, etc., are important, as well as accuracy,for conveying the character of a particular assemblageand for creating the all-important visual harmony ofa set of drawings. The specialist will want the lithicillustrations to display the overall impression of thenature of the assemblage being analysed, and goodillustrations in this regard will be far more successfulthan many pages of descriptive text.This guidebook has been kept intentionally brief toreduce costs and increase availability, but is designedto contain enough information for the intendinglithic illustrator to proceed effectively. Those seekingmore detailed and technical guidance and a widerrange of model illustrations should consult the worksby Addington (1986) and Dauvois (1976).Working with the lithic specialistThe best drawings are achieved when there iscollaboration between the illustrator and the lithicspecialist. This sounds obvious, but it is all toocommon for such collaborations to founder underthe pressures of publication deadlines, disagreementsbetween specialists and excavators, and so on.Ideally the illustrator should not begin work onthe illustration of a group of lithic artefacts untilpreliminary notes on the drawings are supplied bythe specialist. Certainly the illustrator should neverprepare publication drawings for an excavator beforea lithic specialist has been engaged - otherwise there isa risk that the illustrations will have to be completelyredrawn or that entirely different artefacts will beselected for illustration.Preliminary notes from the lithic specialist shouldindicate the level of illustration, whether fully detailedor schematic; the orientation of each artefact relativeto an upright page; the number and position of viewsand sections; the position and nature of any specialfeatures such as edge gloss; and the full referencenumber and site code of each object. All drawingsshould be examined by the specialist at the pencilstage, so that if any corrections are necessary they canbe made before inking.Understanding the specialist’s requirements can bedifficult, if not impossible, without some knowledgeof basic lithic technology and typology (Fig. 1).Background reading of introductory texts will help(e.g. Bordaz 1970 and 1971; Pitts 1980; Timms 1974;Watson 1968), but is no substitute for the observationof a demonstration of flint-knapping techniquesby a modern practitioner. Such demonstrationsare increasingly common as a component of dayschools organized by archaeological groups anduniversity extra-mural departments. Familiarity with1

the terminology of flaking used by the specialist such terms as striking platform, bulb of percussion,bulbar scar, faceted butt, etc. (see Fig. 1) - will be veryuseful to the illustrator. There are clear differences inquality between the drawings of those illustrators whounderstand the principles of knapping and those whodo not.Equally, the specialist must be aware of the needsand level of knowledge of the illustrator and of theconstraints under which illustrators often work. Forexample, the specialist may have access to publishedor unpublished work unavailable to the illustrator, andshould supply photocopies of relevant drawings. Norneed communication between specialist and illustratorbe one-way, since feedback from the illustrator canoften improve the specialist’s understanding of detailson a particular artefact.outer surface of a stone pebble may remain on someartefacts, and are usually represented by stippling (seeFig. 2). To be able to indicate the humanly struckareas on worked flint, which are normally apparentas negative flake beds or scars, it is essential tounderstand the direction of each flake removal. Flintfractures conchoidally, that is in a manner resemblingthe curved, concentrically ribbed surface of someshells. In other words, from the point of impact orpercussion where the hammer strikes the flint surface,a series of concentric ripples are formed which areoften visible both on the bulbar surface of the struckflake and on the negative flake scar left on the coreor implement being worked. These ripples must berecorded to indicate the direction of flaking involved,and are usually drawn in continuous curved lines, thebest effect being obtained with a split-nib pen thatallows a variable line thickness (Fig. 3).Some implements, like piercers, may comprisesimple flakes on which little or no readily visiblemodification has taken place, while in other cases - abarbed-and-tanged arrowhead for example - a flakemay be very elaborately retouched into the requiredform. Such elaborate retouch or secondary workingmay involve very small, precise flake removals, forwhich it is important to record the exact directionof flaking. With some implement types, such as endReading the artefactA single lithic artefact may have several differenttypes of surface area visible, each requiring separatestylistic treatment. For example, there may be naturalfractures resulting from burning or freeze-thawclimatic conditions, which must be distinguished onthe drawing from humanly produced facets.

The way in which flake scarsare truncated and shaded will indicate the order offlake removals (Fig. 5) and a successful drawing willallow the flaking ‘history’ of an artefact to be read.When an artefact becomes ‘rolled’, normally bythe natural friction created by movement in wateror gravel for long periods, it loses the sharpness ofthe ridges between flake scars and flake faces whichis a feature of freshly struck pieces. These bluntedand blurred features must be faithfully reflected inThe flake ripples will not always be readily apparent(though they may ‘emerge’ under magnification or byholding the piece of flint sideways to a light source)and it is often necessary to indicate them somewhatschematically. Cracks and crystal pockets whichoccur naturally in flint should be shown realisticallywherever possible, as these faults can cause a changein direction of flake ripples, and their inclusion canexplain the presence of an irregular flake scar. If suchfaults are profuse, however, a balance must be kept inthe drawing to avoid obscuring the details of flakingand retouch.As important as the direction of flake removals isthe sequence in which those removals have taken placeon an artefact. The most recent negative flake scar onFig. 4 Complete and truncated flake scars: a) complete scar withprogression of ripples from very curved at the base to shallow at thetop; b) scar with bulbar end removed leaving an area of shallowripples; c) scar with distal end removed leaving the curved ripplesin the area of the negative bulb; d) scar truncated longitudinally.Original drawing reduced by 50%.the drawing when ‘rolled’ artefacts are illustrated,normally by leaving open the intersection of the flakescars (Figs. 9 and 18), or by depicting the intersectionas a dashed or stippled line rather than a solid one.All lithic flake tools have an under surface (bulbaror ventral) and an upper surface (dorsal). Normallyonly the dorsal surface is illustrated, together with aside view or a cross-section or profile.

Fig. 5 A fragmentary pick (flint) used as an example of the analysis of the order of flake removals. The flatter, ventral surface (view I) wasprobably the first to be flaked and the numbers 1-11 show the possible order of removals, with 0 being the only remainder of the originalbulbar surface. It can be seen that flake scars 1-11 are all truncated at their proximal ends, lacking negative bulbs of percussion. Thistruncation was caused by the four main steep removals from the dorsal surface (view 2a). The sequence of these large scars on the dorsalsurface can be determined since flake scar B invades A and therefore postdates it, similarly scar D postdates C. Flake scar X, struck from theextremity of the implement, predates removals B, C, and D, each of which truncates it. The final stage of flaking involved the removal ofsmall trimming flakes along the edges of the ventral surface (view 3), and these retain their negative bulbs of percussion. The publicationdrawing of this implement would comprise views 2a and 2b, views 1 and 3 being included here only to demonstrate the kind of analysiswhich would take place in the mind of the illustrator during the process of drawing the implement. Despite the overall similarity in the wayin which the flake scars are depicted in views 2a and 2b, it is still possible to determine the sequence of flake removals from the drawing,showing that the illustrator has understood the way in which the implement has been flaked, thus in turn allowing the flaking history to belegible to the viewer. Drawn at 1:1 for reproduction at 2:3.restricted to the dorsal surface, while the ventralsurface simply comprises a single, positive, flakesurface. The same applies to totally unretouchedpieces, since the chief interest of the artefact probablywill lie in the pattern of negative flake scars formingthe dorsal surface.Side views and profiles are placed directlyalongside the dorsal view. There has in the past beenconsiderable variation in which side of the artefact theaccompanying side view has been placed against, andin which direction it was shown to face. Such variationbecomes extremely confusing if there is inconsistencywithin a given set of drawings. (For an example ofthis kind of inconsistency see Saville 1981a, wherethe use of variable positioning by different illustratorshas created an odd effect once the drawings have beenmounted together.) In fact, unless a standardizedprocedure for positioning views is employed, thereader can never be entirely sure which side view iswhich. It is recommended here, therefore, that the socalled ‘American projection’ of aspect conventions, asshown in Fig. 6, is followed in all cases. Any deviationfrom this system should be carefully labelled to showwhich view is being depicted.Vertical cross-sections are placed to the right of thedorsal w, and centrally between the dorsal and ventralviews if both are drawn. Horizontal cross-sections canbe placed above, below, or to the side of the dorsal viewaccording to where they fit best in a particular instance.The cross-section of a particular part of an implement,such as the tip of a piercer (Fig. 22), should be placedalongside the position of the section, with link-lines ifnecessary to make the relationship clear.The colour of an artefact, where relevant, isdescribed in the text and not by the illustration.Fig. 6The aspect conventions for illustrating various views ofthe same artefact. This system, know as orthographic or Americanprojection, requires each new view to have the same surfacesadjacent. If the artefact were a flake, then A would be the dorsalsurface and B the bulbar one.4

The same is normally true of variations in surfacecolour occurring on a single artefact; in the case offlint artefacts such variation will usually be postdepositional and of no significance for the originalmanufacture and use of an implement. Colourbanding or variegation on stone implements, wherethis is thought to relate to the original selection ofraw material, may need to be depicted (e.g. Roe1968, fig. 36a), but can also be achieved inexpensivelyby publication of a monochrome photograph tocomplement a drawing (e.g. Roe 1985, figs. 8-9).reference to normal conventions (see below), thefollowing sequence of drawing stages may be adopted.1. Place the artefact flat on the drawing surface(whether plain paper, graph-paper, or tracing- paperor drawing-film over graph-paper), if necessarysteadying it with a wedge of ‘Blu-tack’. Avoid unduepressure on delicate flint artefacts when using ‘Blutack’; longitudinally curved pieces can easily snapwhen pressed against the hard surface of a drawingboard.2. With the lead of a pencil held perpendicularto the drawing surface and vertically positionedagainst the side of the artefact, draw carefully aroundthe edge to achieve the outline (Fig. 7a). Beforecontinuing, check the outline by holding a setsquare upright against various positions around theartefact’s perimeter. Take care to avoid damaging theedges of delicate artefacts with the lead of the pencil;if necessary use a series of dots on the paper to keyin the main features of the outline, determining theirposition with an .upright set-square set against theedge of the artefact, then join up the dots by eye.3. Key in on the drawing the junctions of the mainflake removals on the surface to be illustrated at thepoint where they intersect the outline (Fig. 7b), againusing a set-square if necessary.4. Place a sheet of rigid perspex (or glass) overthe artefact, supporting it on suitable props to bringit flush with the surface of the artefact and parallelto the surface of the board. Trace the inner ridgesbetween the flake scars and any other surface details,either directly on to the perspex, or on to acetatedrawing film taped to its surface (Fig. 7c). The tracingmay be easier if the surface details of the artefactPractical IllustrationLithic artefacts are normally drawn at actual size(1:1), except in the case of very small implements,like some microliths, which may be drawn at twicelifesize (2:1). The subject of reduction is discussedfurther in a following section. It should be notedthat there is a school of thought which advocates thedrawing of almost all lithic artefacts at twice lifesize,to permit easier depiction of finer detail and to allowsubstantial reduction to publication size to ‘crispen’the image. This practice has been the rule in thearchaeological drawing-office of the Department ofthe Environment (now English Heritage) at FortressHouse, from where many influential illustrations haveemanated (e.g. drawings of flint artefacts in Saville1981a and Wainwright 1979). The technique relieson the availability of mechanical visualisers, however,without which the production of numerous enlargeddrawings is too time-consuming to be practical.Assuming the artefact is to be drawn at actualsize, and assuming that the orientation has beendetermined from the specialist’s instructions or byFig. 7Stages in the illustration of the dorsalsurface of a flake (see text for details).5

have previously been highlighted by running a softpencil directly along the flake ridges, etc. (Such marksshould be removed before returning the artefact to thespecialist!)5. Transfer the internal details on to the paperwith the outline (Fig. 7d), using a light-box ifnecessary. This stage can be avoided by using the sametransparent sheet for the outline and the tracing.Note that not every illustrator will choose to usethe perspex sheet technique, developed by one of us(H.M.) as a rapid method for producing accuratedrawings. The technique is perhaps most useful onpieces with complex retouch or where there is a lotof depth to be compressed into the horizontal plane.Other illustrators prefer to measure numerous keyrelationships, sometimes using a compass to plotridge junctions by intersecting arcs, while experiencedillustrators often work mainly by eye: see Addington(1986, 56).6. Check any doubtful relationships between thesurface details by measuring from object to drawingusin
