    Received March 25, 1997; revision received June 24, 1999; accepted October 4, 1999

    Evidence concerning use of space in caves and rockshelters by present-day foragers and

    horticulturists in tropical and arid regions is reviewed. The implications of this evidence for

    cave/rockshelter archaeology are investigated. The various ways in which p eople from d ifferentcultural backgrounds adapt to naturally confined locations are described. Patterns of refuse

    disposal, the role of hearths, and the possibility of identifying activity areas are also explored.

    It is suggested that spatial adap tations to th ese sites are d etermined not b y the constraints that

    these present to their occupants but by the ways in which the occupants perceive and experi-

    ence space. An account is given of those dimensions of variability in site structure that appear

    likely to be u seful in form ulating a n ew agen da for spatial analysis of Palaeolithic and Mesolithic

    sites containing palimp sests of material. Finally, the necessity of adopting a comparative

    approach in order to understand the elements of spatial site structure is stressed. 2000 Acade m ic

    INTRODUCTION

    Spatial analysis of Palaeolithic or Meso-

    lithic sites is intended to shed light on the

    spatial behavior of prehistoric foragers in

    t h eir ca mp s it es . In s p ire d b y e th n o ar-

    chaeological observations concerning the

    use of space by living foragers, it has b een

    furthered by the introduction and wideadoption of compu ters an d quan titative

    m ethod s in ar chaeology. Althou gh an alyt-

    ical techn iqu es for pattern iden tification

    have un dergone considerable refinem ent,

    however, spatial analysis of caves and

    rockshelters 1,* h a s m a d e on ly a lim it ed

    contribution to our understanding of pre-

    historic spatial beha vior. This is to a large

    extent because most of the interpretativemodels of spatial organization assume a

    context created by synchronic deposition

    of archaeological material. Such contexts

    are seldom found. The vast majority of

    Palaeolithic or Mesolithic sites found in

    these naturally confined locations are pal-

    im psests of debris from m ultiple sup erim-

    posed occupations. In recent years prehis-

    t oria n s h a ve o n t h e w h ole a gre ed t h at

    t h e re i s a n e e d fo r a p p ro a c h e s t h a t a re

    specifically app rop riate to sites containing

    p a limp s e st s o f cu lt u ra l ma t eria l (C a rr

    1987; Gamble 1991). If we are to acquire

    from these sites worthwh ile information

    about sp ace use, we mu st first identify the

    behavioral issues that appear most likely

    to be clarified by studying spatial varia-

    tion in palim psests. The un its of observa-

    t io n a n d o f a n a lys is b e st s u it ed t o t h e

    drawing of valid inferences about past be-

    havior in caves mu st also b e found. As a

    first s te p , t h e e th n o arch a e olo gy o f c/ r

    must be examined more closely.

    information about how prehistoric forag-

    ers lived, few ethnoarchaeological studies*See Notes section at end of article for all foot-

    hearths, stone-lined hearths, log-lined

    h e a rt h s, a n d roa st in g p it s o r o ve n s, a t

    tim es associated with firestones. With the

    exception of the ovens, whose specialized

    fun ction it is to roast gam e or vegetables,the data to h and suggest that there is no

    direct relationship between hearth form

    and hearth fun ction. All the othe r types of

    hearth are u sed for m ultiple pu rposes, in-

    clu d in g co ok in g , s le e p in g b y, g ivin g

    warmth and light and acting as the point

    around which people relax, chat, interact

    socially, or perform ceremonies.

    Since only the b are m inimu m of energyn e ed b e in ve ste d in b u ild in g a n op e n

    h e a rt h , w h ile t h e co n st ru ct io n o f a n y

    o th e r t yp e o f h e a rth re q u ire s a g re at er

    investmen t of energy, we can test the in-

    tuitive hypothesis that the amoun t of en-

    e rgy in ve st ed in ma k in g h e a rt h s (a n d

    hen ce the types of hearth constructed) re-

    lates to the length of time for which a site

    is occupied. I have divided the possibletypes of hearth into two energy invest-

    ment categories: the low-investment cate-

    gory contains the open hearths and the

    h ig h -in ve st me n t ca te go ry e ve ry o th e r

    type. I have also used the data from Table

    2 to group sites according to whether they

    are used for brief stays or for longer ones.

    The chi-squared test of independence be-

    tween length of stay and amount of en-

    ergy invested in h earth s (Table 3) suggests

    that there is no significant difference inthe distribution of high and low energy

    investments in hearths used during brief

    and longer term occup ations. Therefore,

    hearths requiring a high energy invest-

    ment do not necessarily relate to longer

    stays.

    he arth s relates to the de gree of mobility ofthe occupying group. Un like the previous

    test, the chi-squared test here suggests

    that in our sample there is a relationship

    between degree of mobili ty and amount

    of energy invested in hearths (Table 4).

    Gu inea (Figs. 36). It is notewor thy that

    two foraging groups (the Australian and

    South African ind igenous) of the three in

    o u r s a mp l e u s e t h i s t y p e o f h e a rt h , a l -

    though op en h earths are n ot the only type

    found in forager sites. They are, however,the only type present in the sites used by

    the Sawos, who make clay pots to cook in,

    a nd w ho, ju d gin g b y th eir fu r nitu re

    (wooden beds and tables), appear to be

    one of the most sedentary groups in our

    sample (Gorecki 1991). In the Big Elephant

    Cave, the site used by the third foraging

    group in our sample (the BergDama), only

    stone-lined hearths were found (Fig. 7).

    To summarize the above, we have no

    evidence for any relation between length

    of occupa tion an d type of he arth an d the reis a weak relationship between degree of

    mobility and type of hearth. Table 5 sug-

    gests that some relationship may exist be-

    tween cultural group and type of hearth

    used . This pattern is mu ch more r obust in

    the foraging groups in our sample (the

    BergDam a, South African indigenou s, an d

    Australian aboriginals) than among the

    horticulturists.

    Number of Hearths

    The scattergram plotting total num ber

    of hearths against si te area for each site

    (Fig. 8) clearly su ggests th at th e r elation-

    ship be tween th ese two variables is not a

    Th e n u m b er of h ea rth s u se d d u rin g

    each episode of occupation is first and

    foremost a culturally defined element of

    habitation. It is only secondarily a func-

    tion of the size or social comp osition of the

    occupying group and of the character ofon-site activities (Table 6). The evidence

    w h ich t h e a b ove p a rame t ers a ffe ct t h e

    num ber of hearths used per occup ational

    episode differs from one culture to an-

    other. For instance, Nicholson and Cane

    have observed that in Australia the num-

    ber of hearths relates to the size of the

    occupying group (1991), while Gorecki hasreported that in Papua New Guinea the

    Pinai people u se only a single hearth per

    occupation regardless of the num ber of

    occupants (1991). At Yeleme-Wang-

    SLEEPING ARRANGEMENTS

    Sleeping is one of the most elusive as-

    pe cts of hum an activity in th e archa eolog-

    ical record. In spatial mod el bu ilding it is

    often treated as a variable about which

    cross-cultural gen eralizations m ay app ro-

    priately be made (see, for example, Bin-

    ford 1983:162163). The review of th epresent data has shown that sleeping ar-

    eas are always adjacent to hearths, but

    that n ot all of a sites h earths are used for

    sleeping by. There is considerable varia-

    tion in the location of the sleeping area

    and the type of bedding p referred (Tables

    79). In Me lpa, Pinai, an d South African

    sites the sleeping area is near the back

    wa ll of th e cave (Figs. 1011, 3) (Gor ecki1988, 1991; Par king ton an d Mills 1991).

    The Australian aboriginals sleep at the

    centers of rockshelters, after clearing

    these areas of objects (Fig. 5) (Nicholson

    an d Can e 1991). Th e W est Dan i at

    Ye le m e -W an g- Ko b-M e s le ep a rou n d

    hearths in depressions that correspond to

    dom estic un its [Fig. 9(2)]. These un its ar e

    distributed all over the shelter floor. De-pending on their village of origin, and

    hen ce on their cultural h abit, the sleepers

    either use pandanus mats as bedding or

    sleep on the bare ground (Petrequ in and

    Petre q u in 1988). The BergD am a wh o us e

    the Big Elephant Cave also sleep in living

    hollows, in this case consistently foun d by

    the rear wall of the site next to a hearth

    (Fig. 7) (Clark and Walton 1962). Thesleeping area in Melpa sites overlaps with

    the gen eral dom estic activity area an d has

    no fixed position; it can, for example, be

    by the back wall of the shelter, as at Nip,

    or in the center of the rockshelter, as at

    Temb inde (Fig. 10). Using plan t m aterials

    wooden beds (Table 9; Fig. 6).

    The variation in sleeping arrangements

    observed in our sample makes it clear thatthis is another culturally de fined variable

    in spatial adaptation to c/r. Since this is

    the case, we could obtain far more infor-

    ma t io n from a rch a e olo gica l co n te xt s

    about how people slept by adopting an

    ind uctive research procedure consisting

    of a descriptive and a comparative stage.

    My proposal would be th at the researcher

    should begin by recording the location of

    the h earth in relation to cave features su ch

    as walls, drip lines, or talus slopes, then

    pr oceed to consider th e sites fun ction an ddu ration of occupa tion. By this stage h e or

    she will probab ly have some inkling as to

    where (if at all) sleeping may have taken

    place. This suspicion may develop into a

    plausible hypothesis once the location of

    the hearth or hearths has been compared

    refuse-d isposal habits of differen t cultur al

    group s give r ise to sites of variable d en sity

    an d conten t. The sam ple of sites examined

    here has told us nothing about how dis-

    card behavior may vary according to the

    length of time for which the site is occu-

    pied, the nature of the activities carried

    out in it, or the social composition of theoccupying group. Although we can safely

    argue that people discard their refuse in

    ways specific to their cultures, then , we d o

    not as yet know how useful this general

    statement is to the study of archaeological

    contexts. If, on th e one han d, the cultural

    imprint is as strong as our data are sug-

    gesting, archaeological sites used by the

    same cultural group should exhibit iden-tical traits, generated by discard behavior

    that is specific to that culture. If, on the

    other hand, the details of an occupation

    (its len gth, the na tur e of the activities per -

    formed during it, or the social composi-

    tion of the occupying party, for instance)

    influence refuse disposal patterns more

    strongly than any cultural imp rint, this

    should be detectable by comparing sites

    used by the same cultural group but for

    differen t pu rp oses. In either case, the on ly

    viable way of learning more about discard

    b eh a vio r is to a d op t a con te xtu a l a p -

    pr oach, conside ring pa ttern s of refuse d is-posal alongside a sites other traits (its

    fun ction or any seasonality in its occupa-

    tion, for instance) and seeking intersite

    perspectives upon intrasite spatial varia-

    tion.

    ACTIVITY AREAS

    Since the 1970s activity area researchhas been at the core of most archaeologi-

    cal studies of Palaeolithic and Mesolithic

    spatial organ ization. In all this tim e, how-

    ever, crystal-clear patterns of the sort re-

    whether this translation of artifact or eco-

    fact concentrations into activities is valid(Ga lan id ou 1997b:276277). In th is s ection

    I discuss the particular problems associ-

    ated with attemp ting to identify an d iso-

    late activity areas in caves.

    We d o not h ave information relevant to

    this concept about every site in our sam-

    ple, partly because some were examined

    d u rin g t h e a b se n ce o f t h eir o ccu p a n ts .

    The sites abou t which we do h ave this sortof information (only 11 of 35) fall into

    three types of arrangem ent with regard to

    activity areas (Table 11). In the first ar-

    rangement the general activity area over-

    laps with the sleeping area. This type is

    r ep r ese nte d b y two site s u se d b y th e

    Melpa people (Fig. 10) (Gorecki 1991). In

    the second arrangement sleeping is sepa-

    rated from other domestic activities. Thistype is represented by the four South Af-

    rican sites an d by Big Eleph ant Cave NW

    (Clark and Watson 1962; Parkington and

    Mills 1991). The third type is re pr esen ted

    only by Yeleme-Wang-Kob-Me, where,

    Petreq uin inform s us, som e activities ar e

    rigidly segregated in space while others

    overlap (1988) (Table 11). Strict rules thusgovern where certain activities should be

    performed. If we were to draw a cross-

    cultural conclusion from our sample, we

    would have to suggest that spatial segre-

    gation of individu al domestic activities

    was the exception rather than the rule.

    mestic activities were performed. In somecases these activities may ne ver have b een

    confined to any particular area in the first

    place; in others th e palim psest effect may

    h a ve o bs cu re d t h e fa ct t h at t h ey w ere

    originally segregated in space. In either

    case the resulting deb ris will have woun d

    up in a m idden that we can call the area of

    general d omestic refuse .Once the site has

    been abandoned it is impossible to workout wh ether this area contains m aterial in

    primary deposition overlapping with an

    area of general activity, material in sec-

    ondary deposition, or a combination of

    both. Midd ens of this sort were presen t in

    the m ajority of the sites discussed in Table

    11. In Australian habitation sites, artifacts

    associated with su bsistence activities ten d

    to be found outside the sheltered area (Ni-

    cholson and Cane 1991:345). It is, however,impossible to isolate individual activities

    (t o s ep a rat e t h e ma n u fa ct u re o f s to n e

    cause it is u ncertain wheth er the artifacts

    associated with these activities arrived in

    the area by being dropped, tossed, or re-

    deposited.

    We ha ve seen th at some cultural group s

    may indeed segregate their domestic ac-tivities in c/r, whereas others do not. In

    the former case, however, the constraints

    imposed by limited space and the super-

    has been recorded at four sites. The first

    two, used b y BergDam a hu nter/ gatherers,

    were found in the Big Elephant Cave in

    Na m ibia by Clark an d Wa lton (1962). Two

    sets of roughly circular depressions, de-

    fining dom estic un its, had been d ug in thefloor of the cave, one set in each of the two

    sites into which the cave is divided. The

    depressions in the northwest site were to

    the rear of the cave (Fig. 7). They were

    separated from each other by bru shwood

    screens and contained hearths and beds

    (made of p lant materials). The depres-

    sions in the northeast site were smaller,

    revealed no traces of bedding or screens,and appeared to be much older than the

    ones to the northwest. We h ave no infor-

    m ation abou t the social com position of the

    groups that used the depressions.

    domain is achieved by m eans of two d if-

    ferent types of space division, one physi-cal and one symbolic (1988). The physical

    division involved circular and rectangular

    de pr essions (Fig. 9). During the ep isode of

    o ccu p a tio n re co rd e d t wo d e p res sio n s

    were u sed, one accomm odating four men

    from the village of Yeleme an d th e othe r a

    sim ilar nu m ber from the village of Faoui.

    Each depression delimited its groups do-

    mestic area and had a fireplace at its cen-ter. (Depressions of this sort are some-

    times used repeatedly during successive

    episodes of occup ation.) O utside the de-

    pressions, in the com m un al space, activi-

    t ies such as stone or bone working and

    roasting and sharing gam e took p lace. Al-

    t h ou g h t h e me n from e a ch villa ge h a d

    their own way of using th e private space

    of each depression (this could be seen int h e ma n n e r in w h ich t h ey s to re d t h eir

    personal belongings, for instance [Fig.

    9(4)], both group s sh ared a single attitud e

    to sitting down in the communal area: it

    was strictly forbidden to sit on the bare

    rock or earth. This relates to the symbolic

    division of the site into areas of different

    de grees of im pu rity. The Petreq uins ha ve

    shown that the organization of space that

    th ey e ncou n te re d a t Ye le m e-W an g-

    Kob-Me transposed the spatial arrange-

    ment of the mens house (buildings ineach village use d for social, p olitical, and

    religious purposes by men only) into this

    temp orary rockshelter hab itation (ibid:7680).

    The Melpa people who stay for short

    periods at Nip also incorporate elemen ts

    of their permanent sett lement into this

    temp orary one. The Melpa u se logs as p il-

    lows in their permanent dwellings. At Nipthey choose logs as their means of divid-

    ing space tangibly, using them to delin-

    eate the overlapp ing sleeping an d d omes-

    tic activity areas (Fig. 10). The perimeter of

    the h earth imm ediately beside th is area is

    also marked by logs.

    The sizes of the sites that are divided

    in to sm a lle r u n its r an ge fr om sm a ll

    through medium to large (Table 2). Thisclearly suggests that the size of the area

    used during an event of occupation is not

    directly related to the amount of space

    available. It app ears m ore likely th at cer-

    tain groups use the space inside caves so

    as to reproduce the familiar spatial ar-

    rangem ents that they prefer in their open-

    air settlem ents.

    It is also evide nt th at a grou ps techn icalskills an d experience of certain construc-

    tion materials produce distinctive spatial

    patterns inside caves. This can be seen at

    Nip and also at Balof, a site used by the

    indigenous people of New Ireland, who

    divide up its space by means of terraces

    and stone walls (Fig. 4). There are similar

    This last observation raises a number of

    questions. Do all cultural groups repro-

    du ce distinctive form s of spatial organ iza-

    tion when camping in caves? How do the

    chara cter of the occupation and the social

    comp osition of the occup ying group affectthese spatial arran gemen ts? How m any of

    these pattern s are archaeologically visi-

    ble? The second site used by the Melpa

    peop le, Tem binde, shows that our sam ple

    can give us no unequivocal answers to

    these q uestions. There are n o logs at Tem-

    binde. We d o not know, however, whethe r

    site formation processes have destroyed

    logs that were once there or wheth er therenever were any logs (Fig. 10). To answer

    our qu estions more satisfactorily would

    r eq u ir e a m u ch la rge r s am p le of d a ta .

    Nonetheless, the data to hand show that

    more often than not the layout of living

    surfaces in c/r incorporates at least some

    of the arrangements that the occupying

    group would make in an open site. Our

    data also suggest that the constraints im-posed by a cave do not prompt cross-cul-

    turally uniform spatial adaptations, that

    each cultural group occupying a c/r uses

    its own p articular techn ical skills an d pr e-

    ferred m aterials to create in its tem porary

    dwelling the living conditions with which

    it is familiar. Finally, our sample is suffi-

    cient to confirm that archaeological visi-

    b ilit y s h ou ld b y n o me a n s b e t ak en a sread. Yeleme-Wang-Kob-Me shows us

    that site structure may not merely consist

    of its evide nt featur es, but m ay entail con-

    ceptua l or symb olic organization of space.

    This sort of structure does not, of course,

    leave an y tangible rem ains and thus does

    not survive in the archaeological record.

    SITE FURNITURE AND GROUPIDENTITY

    Site furniture is any artifact, feature, or

    structure that has been made or brought

    into a site to facilitate human activity. The

    plots showing the presence or absence of

    certain site features and items of furniture

    suggest that there is a certain amount of

    consistency in the selection of artifacts

    and features found in the m ajority of the

    sites used by each cultural or linguistic

    group (Figs. 1218). In m any cases them ost robust pa ttern is seen in the absen ce

    of certain categories of artifact or feature

    from the sites used by a single cultural

    group.

    As we saw in the p revious section, dug-

    out hollows that defined domestic areas

    were found in the two sites used by the

    BergDam a and at Yeleme-Wan g-Kob-Me.

    Windscreens wer e consistently present inall but one of the Sandawe sites (Fig. 13).

    The South African sites invariably con-

    tained sleeping hollows (Fig. 3). Walls

    m ade of stone were p resent in three of the

    four sites studied in New Ireland and in

    Big Elephant Cave (Fig. 14). Artificial sand

    ridges were r aised at the ed ge of the site to

    stop water from getting in only at Austra-

    lian habitation sites (Fig. 15). Grindstoneswere record ed in sites u sed b y th e

    Sandawe, the BergDama, and the Austra-

    lian Western Desert aboriginals (Fig. 16).

    Only three of the rockshelters examined

    in New Guinea had stone-lined hearths;

    all three were in the Yuat gorge, and all

    three were used by the Pinai people (Ta-

    ble 5, Fig. 17) (Gorecki 1988, 1991). Not all

    of the Pinai sites contained stone-linedhearths, however (Fig. 11). Similarly,

    wooden beds were found only in sites in

    the Chuigai hil ls that were used by the

    Sawos people, but not all of the Sawos

    sites contained wooden beds (Fig. 18)

    (Gorecki 1991). Site furniture appears to

    be a strong cultural m arker regardless of

    whether a site is as minimally furnished

    as the South African c/r or w he ther a lot ofe n er gy h a s b ee n in ve ste d in cr ea tin g

    built-in beds, storage platforms, or stone

    walls.

    Yeleme-Wang-Kob-Me is used as a tem-

    porary cam p d uring exped itions to quarr y

    basalt and manufacture axes, which are

    subseq uen tly exchan ged for p igs. Wom enare strictly excluded from these expedi-

    tions, and it is therefore significant that

    the spatial organization should reprod uce

    the arrangement of the equally gender-

    sp ecific m en s h ou se (Petr eq u in a n d Pe-

    treq uin 1988). The gr indston es in som e of

    the Australian Western Desert habitation

    sites have also been associated with gen-der-specific activities. It has been argued

    that grindstones are gender-specific arti-

    Site structure can, like other aspects of

    m aterial culture, have a twofold fun ction.

    During an occupation it expresses the oc-

    cup ying groups ideas about spatial orga-

    nization, thus ensuring familiarity andcomfort. Cultural variation in site struc-

    ture can , howe ver, also be a m ean s of non -

    verbal commu nication that transmits a

    m essage about cultural iden tity and rights

    of access to rockshelters, as in Pap ua Ne w

    Guinea. Caves and rockshelters used by

    groups that exhibit territoriality are re-

    garded as resources within that groupsterritory. During the period that elapses

    between two occupations of a site, its site

    structure acts as a marker that lays claim

    to the site. A review of the literatu re listed

    in Table 2 reveals th at th e r ights of access

    to a c/r are always clearly defined. They

    Papua New Guinea are often inspected to

    e sta blis h w h eth e r a n y oth e r t rib e h a s

    been making use of them, by implication

    intruding up on or stealing a resource(persona l com m un ication). In the absence

    of the rightful owners of these sites,

    their site fur nitur e clearly ann oun ces their

    identity and their claim to certain rights

    over the surrounding territory.

    The particular spatial site structure of a

    cave or rockshelter is the result of a cer-

    tain groups way of adapting to specific

    constraints, and as such it signals groupidentity. It follows that site structure

    s h ou ld h a ve re d u n d a n t ch a ract eris tics

    that transcend individual episodes of oc-

    cupation. This point may prove useful in

    making inferences about archaeological

    sites. We do not know whether any pre-

    historic foragers organized themselves

    territorially (see Layton 1986 for a discus-

    sion of territorial organization amongmodern foragers) or whether, if so, they

    expressed group identity and negotiated

    boundaries using spatial site structure as

    a me a n s o f n o n ve rba l co mmu n ica tio n

    (Lightfoot an d Mar tine z 1995). It would,

    howe ver, be extrem ely interesting to test a

    wor kin g h yp oth esis th at th ey d id so

    against the archaeological evidence.

    DISCUSSION

    The sample of sites discussed here, al-

    beit small, illustrates the diversity of the

    ways in which different groups use c/r

    s p a c e . W e h a v e s e e n t h a t t h e s e n a t u ra l

    niches are resources whose size d oes not

    affect whether they are occupied or for

    how long. Although the sort of space th ey

    offer is much the same across the globe,each cultural group adapts to that space in

    a different way according to how it per-

    ceives and experiences space. This is best

    illustrated by Papua New Guinea, where

    c/r space is used in highly variable ways

    even though the c/r are used for similar

    purposes by groups who share the same

    habitat an d have identical modes of sub-

    sistence.Spatial adaptations to c/r may involve

    ph ysically altering their top ograp hy, orga-

    nizing their space conceptually, or doing

    both. Some groups set up camp s in c/r in

    mu ch the same ways as they do in open-

    air locations, using the technical skills and

    spatial archetypes embedded in their cul-

    ture or social category to prod uce th e sort

    of spatial configu ration to wh ich th ey are

    accustomed.

    Overall differences were observed be-

    tween forager and horticulturist use of space. The sites used by the Australian

    and South African foragers are minimally

    furnished and lack durable structures of

    an y sort. The We st Dani at Yelem e-Wan g-

    Kob-Me dig depressions in the shelters

    floor and organize its space symbolically

    so a s to m a ke it a m e ta ph or for th eir

    m e n s h ou se . O th e r h or ticu ltu r ist

    groups in New Guinea wh ose backgroundis fairly sedentary choose to invest their

    t ime and energy in lining hearths with

    stones, in constructing wooden beds and

    tables, or in making artificial roofing. The

    data to date thus suggest that m ore energy

    is invested in the construction of habita-

    tion features by horticulturists than by

    foragers.

    Our sample thus contains evidence ofcultural and economic variation in site

    structure. We h ave also seen that th e spa-

    tial structure of separate sites used by a

    single group may be different, as in the

    case of certain sites used by h orticultur ists

    such as the Sawos and the Melpa (Figs. 6

    and 10). Although the small size of our

    samp le an d our lack of detailed site biog-

    raphies do not p ermit elaboration on thisissue, we m ay susp ect th at th is differen ce

    probably relates to differences in site

    function or in the social composition of

    the occupying parties. In other words, it

    pr obab ly refle cts variability in the iden tity

    of the occupants. For example, different

    ge n d er or a ge gr ou p s w ith in th e s am e

    comm un ity may experience and use spa ce

    in d iffe ren t w ays . Bo b La yt on h a s re -corded gender-specific rockshelters at

    Uluru (Ayers Rock) in central Australia,

    where Tjukutjapi and Pulari are associ-

    ated with wom en s rituals and W arai Yuki

    and Kulpi Mutit julu with mens rituals

    (persona l com m un ication).

    Ou r review has shown that hearths do-

    mesticate a natural cavity by offering focal

    points around which humans can act and

    interact. The y d ivide sp ace p hysically an d

    conceptually into smaller un its according

    to the needs and beliefs of the occupyingparty. They are thu s structural elem ents of

    spatial organization a nd m edia for th e re-

    pr odu ction of spa tial form s familiar to th e

    occupants of c/r. We have seen that there

    is no evidence that the p resen ce of he arth s

    whose construction demands a high en-

    ergy investment (stone-lined, log-lined,

    ovens) is related to longer term occupa-

    tion. The forager groups in our sampleconsistently used a single type of hearth,

    either open or stone-lined , in m ore or less

    the same place with regard to the shelters

    walls and the talus. The horticulturist

    group s were less consistent in th eir choice

    of hearth type and location. The number

    of hearth s in a site does not app ear to be a

    fun ction of the size of the sh elter. Instea d,

    it is associated with a groups attitude to-ward hearth reuse, with the character of

    the activities carried out there and with

    the social composition of the occupying

    party. The type of hearth chosen, its loca-

    tion, and whether i t is reused are three

    variables that are very important to the

    stud y of site structure in archaeological

    palimpsests.

    Some of the si tes in our sample weree xa min e d w h ile t h eir o ccu p a n t s w ere

    presen t. Their activities were recorded as

    preparing and consuming food, manufac-

    turing objects, participating in leisure ac-

    tivities, and sleeping. Whe n sites wer e ex-

    amined in the absence of their occupants,

    although their floors could be divided into

    zones containing different densities of

    m aterial (see Pakara an d M arind jila in Fig.6, for e xam ple) or concentra tions of a p ar-

    ticular type of find, it was impossible to

    relate these zones with any certainty to

    any specific activity. This is mainly be-

    th e re is n o e vid e n ce to s h ow w h et he r

    finds ended up in their current locations

    by being dropped, tossed, lost, or inten-

    tionally or un inten tionally redep osited. It

    was, m oreover, imp ossible to iden tify th e

    h a b it at io n fe at u re s t h at h a d b e en u s ed

    contemporaneously or to distinguish theboun daries of the m ost recent living fl oor.

    This is because cultural m aterial and fea-

    tures from previous occup ations are in-

    corporated into every current living sur-

    face. Amid this palimpsest we can only

    identify redun dant patterns of site struc-

    t u re t h at ma y o r ma y n o t co rre sp o n d t o

    activity areas.

    A n um ber of lines of evidence suggestthat the c/r used intermittently by certain

    territorial groups tend to contain very

    similar site furniture not only because it

    provides them with familiar living condi-

    tions while they are occupying these re-

    sources, bu t also because it establishes

    their right of access to them even while

    they are somewh ere else. In other words,

    spatial site stru cture in c/r serves just th es ame p u rp o se a s s tyle d o es in ma t eria l

    cu lt u re : it co n ve ys in fo rma t io n a b ou t

    group identity to target groups (Conkey

    1990; W iess n er 1984, 1985). Ar ch itectu ra l

    form, like stylistic form and the iconogra-

    phy of artifacts, is commonly considered

    to be an em blem of group iden tity that can

    permit such identity to be established in

    archae ological contexts (Shen na n 1989).Architecture is a set of recurr ing pr ocesses

    that involves imagining, planning, con-

    structing, and maintaining built struc-

    tures. If we expand this definition to in-

    clude spatial adaptations to c/r, which in

    effect comprise the same series of pro-

    cesses, though carried out inside an exist-

    ing structure rather than involving the

    co ns tr u ction of som e th in g n e w fr omscratch, the relevance of c/r pa lim pse sts to

    the discussion of social identity immedi-

    ately becomes clear. By opening up our

    discussion in this way we can extend it

    mu c h fu rth e r b a ck in t o a p e rio d from

    which very few architectural remains, in

    t h e t ra d it io n al d e fin it io n o f t h at t erm,

    ha ve survived . This app roach seem s likely

    to be of enormous benefit to Palaeolithic

    and Mesolithic research.

    A new approach to the sort of spatial

    variation exhibited in Palaeolithic or Me-

    solithic sites would not attempt to recon-

    struct individual moments of space use,

    b u t w ou ld in s te a d s ee k re d u n d a n t p a t-

    te rn s (p a tt er n s t ha t r u n th r ou gh m o re

    than one event of occupation) in spatial

    structure. This approach could develop in

    several d irections. The version th at I favor

    would seek to iden tify (1) the type of an y

    habitation structures present and their

    disposition in relation to each other a nd to

    certain universal features such as back

    walls, d rip lines, and talus slopes; (2) th e

    density and composition of the assem-

    blages found around hearths or other el-

    emen ts of site furniture; (3) the m ethods

    of refuse disposal used; and (4) whether

    hearths were reused.

    Within this approach the appropriate

    un it of an alysis m ight be the layer (if that

    were sufficiently e xtensive), th e stratum

    (comprising more than one layer), or, in

    some cases, the entire site. Choosing so

    large a tem poral unit should not be prob-

    lematic if we seek to identify patterns that

    are th e resu lt of repetitive spatial beh avior

    rather than of ind ividu al episodes of dep -

    osition of cultura l deb ris.6 The method es-

    sentially involves the same assumptions

    a s t h os e t h at a lit h ic s p ecia lis t ma k es

    whe n h e/ she d ecide s to stud y a sites lithic

    technology not by mean s of refitting, but

    by observing change through time.

    Describing a sites sp atial configu ration

    should n ot be an en d in itself, but a m eans

    of coming to certain conclusions ab out th ePalaeolithic or Mesolithic society that

    gave rise to it. Once the general traits of a

    sites spatial structure have been identi-

    fied, an attemp t should be m ade to estab-

    lish how these patterns are linked to the

    sites role within a larger-scale settlement

    system an d to comp are them with the spa-

    tial patterns of other sites. Few compari-

    sons of this sort have as yet been made

    (althou gh see Galanidou 1999 and Kind

    1985), bu t th e u nd ertaking pr om ises to in-

    crease our understanding considerably.

    For examp le, it could r eveal wheth er com -

    mon patterns of spatial organization can

    be iden tified in sites whose functions were

    s imi la r o r in s it es t h at a re in t h e s ame

    region.

    Archa eological e xcavation of a c/r site

    almost invariably results in the recovery

    of a p alim psest resulting from several oc-

    cup ational episodes. I have argu ed in this

    article that it is both useful and valid to

    study palim psests in term s of large-scale,

    rep etitive pa ttern s of spatial variation. My

    s u rve y h a s s h ow n t h at t h e s p at ia l s it e

    structure of c/r bears a very strong cul-

    tural imprint. This general statement is

    not, of course, the whole story; we have

    still to explore th e ind ividua l traits an d the

    amoun t of deviation from cultural n orms

    that variation in site function may gener-

    ate. We should also begin to treat redun -

    dant patterns in the u se of c/r space as an

    aspect of material culture that may well

    have much more to tell us about cultural

    and social identity, never forgetting that

    intersite comp arison is vital to our un der-

    standing of intrasite spatial variation.

    Perhaps the most significant imp lica-

    tion of this survey is that only if we are

    prepared to alter our theoretical expecta-

    tions and our research strategies will we

    be able to extract new information from

    the Palaeolithic and Mesolithic spatial

    record. We still do not know how detailed

    or how useful to our discussion of past

    societies this information will tur n out tob e , b u t w e a r e n e v e r g o i n g t o fi n d o u t

    unless we start somewhere. The potential

    value of the approach that I propose re-

    mains to be evaluated by m eans of future

    site-scale and intersite comparative stud-

    ies of spatial p atterns.

    NOTES

    1 From now on caves and rockshelters will be re-

    ferred to in the text as c/r.2 As we h a ve v aryin g a m o u n t s o f i n fo rm a tio n

    about these sites (Table 1), most of the fields in the

    database used in this analysis are categorical vari-

    ables recorded as presence/absence.3 W h e re t h e in v es tig a to rs h a ve n o t s p e cifi e d a

    sites size, it h as b een calculated app roxima tely from

    the p ublished plans.4 The Melpa people kindle a fire as soon as they

    arrive at any rockshelter, using firewood that is al-

    ready there. Before they go, they stockpile some

    more wood for the u se of whoever uses the site next

    (Gorecki 1991).5 The spectrum of activities performed in a habi-

    tation site is certainly m uch broader.6 I h a ve s h own e ls ewh e re t h a t i t is p o s sib le t o

    properties, albeit not at the sort of degree of resolu-

    tion that is necessary if specific moments in the past

    are to be reconstructed (Galanidou 1997a).
