Nevertheless it has proved difficult to validate even very general cross-cultural observations about refuse disposal.

regression analysis Techniques for examining the relationship between two (or more) continuous VARIABLES, each measured on a set of

objects from the archaeological record. The simplest linear regression, seeks the best straightline relationship between two variables, and studies the differences (known as residuals) between the ideal and actual data. The extent to which the relationship can be described as a straight line (i.e. that one variable can be exactly predicted from the other) is measured by the correlation coefficient, which can vary from –1 for an exact negative relationship through 0 for no linear relationship to +1 for an exact positive relationship. The term correlation is also used more generally (but wrongly) to mean association (see CONTINGENCY TABLE). More complex types of regression are curvilinear regression (more complicated relationships between two variables) and multiple regression (relationship between one ‘dependent’ variable and several ‘independent’ ones).

Case-study: regression analysis and the distribution of Roman pottery. Regression has been used to good effect in SPATIAL ANALYSIS; for instance, Fulford and Hodder (1974) used regression analysis to study the distribution of late Roman pottery from the north Oxfordshire kilns. They calculated the

proportions of this ware at contemporary sites in southern England, and plotted them against the distances of the sites from the kilns (Fig. 44A). Although, as expected, the proportion decreased as distance from the kilns increased, this pattern was not followed consistently, and there was much unexplained variation.

However, when the sites were divided into two groups – those with easy access by water from the kilns, and those without – the position became much clearer. Each group could be fitted closely by its own regression line, the two lines differing greatly. The sites with access by water had a very shallow regression line, showing that the proportion of the ware decreased only slowly with distance from the kilns, while the other sites had a much steeper regression line, with the proportion decreasing much faster with distance from the kilns (Fig. 44B).

Although this study could be criticized because

(i) the proportions were based on counts of sherds, and (ii) the sites were not necessarily exactly contemporary, so chronological differences may have entered the picture, it clearly shows two distinct groups of sites, and suggests a reasonable interpretation of the difference between them – that the main form of transport of this ware was by water.

Remigia Rockshelter and cave site with one of the most striking concentrations of SPANISH LEVANTINE ROCK ART, in the Gasulla ravine, in Castellón, Spain. The figures, mainly of archers, vary from about 0.05 m to 0.5 m tall, and are painted in red and occasionally black. There are also animals such as deer, boars and goats (including herds of animals as well as single examples); other depictions have been interpreted as beehives, spiders etc. The most famous ‘scene’ at Remigia seems to show an execution: archers wave their bows above their heads as their victim lies in front of them, pierced with up to ten arrows.

residues Term used to describe material surviving on the surfaces of artefacts. For example, residues of such organic substances as blood, hair, bone or cartilage on butchery tools may be identified and characterized (and, more recently, subjected to DNA ANALYSIS). Useful evidence survives only in a small number of depositional conditions and environments. Blood residues, for instance, tend to survive primarily in such protected areas of artefacts as step fractures at the edge of undetached stone flakes.

resistivity survey Technique of nondestructive prospection which was first developed by Schlumberger in 1912, as a means of oil exploration. It relies on the principle that different deposits beneath the ground offer different resistance to the passage of an electric current, depending largely on the amount of water present. A damp pit will offer less resistance than the surrounding soil, while a brick wall will present more resistance. Unusual types of material give anomalous readings that can be plotted in terms of their depth and location.

If the soil conditions are right, and agricultural practice and modern digging has not confused the area too much, resistivity surveys can be an efficient way of locating major structural features across an extensive archaeological site. A typical resistivity survey comprises a linear array of copper rods laid out at regular intervals, with a source of electricity and a meter to measure the resistance at various depths. The resistance is measured along a number of different depths, thus being shown graphically as a set of lines showing the fluctuations in resistance at various depths. Because resistivity surveys measure relative values, they are more effective in some conditions than others. In very wet soils, for example, it may be difficult to distinguish features that reduce resistivity. Resistivity surveys are often used to plan excavation strategies, or to generate a sketch map of major features in the immediate vicinity of an excavation. They may be used in conjunction with another principal geophysical surveying technique, the MAGNETIC SURVEY. The technique has been used at many sites throughout the world (see, for instance, the work of Ian Mathieson at the ancient Egyptian sites of el-

Amarna, Memphis and Saqqara: Mathieson 1984; Mathieson and Tavares 1993).

Rhapta The principal harbour of ancient Azania (East Africa), which is documented in an Alexandrine Greek text of the 1st century AD (The Periplus of the Erythraean Sea). The archaeological site of Rhapta has not yet been located, despite searches along the Tanzanian and Kenyan shores and estuaries (cf. the roughly contemporaneous port of HAFUN). Rhapta’s exports were ivory, tortoise-shell, rhino-horn and pearly shells; the shipping was largely in South Arabian hands but connected with both India and Roman Egypt.

Rhohri industry Palaeolithic stone tool industry identified from the Rhohri hills located to the east of the Indus River near Sukkar in Sind Province, Pakistan. Numerous chert nodules are still visible on the hill tops and in 1975 a brief survey conducted by Bridget Allchin, Andrew Goudie and Karunarkara Hegde resulted in the identification of numerous lithic production sites, dating from the Middle Palaeolithic, Upper Palaeolithic and INDUS CIVILIZATION. These surface sites were dated according to typological variation in lithic forms; no absolute dates are available. The Middle Palaeolithic artefacts include scrapers, cleavers, chopping tools, flakes, blades and cores, while those from the Upper Palaeolithic sites are characterized by higher frequencies of blades and blade cores. The Indus period sites provide evidence for largescale blade production at discrete working floors or activity areas.

gold and has a single riveted handle. It is related in design to a series of small cups made out of gold, silver, amber and shale which have been recovered from roughly contemporary Early Bronze Age contexts across Western Europe. Joan Taylor (in D.V. Clarke et al. 1985) suggests that the piece may even have been made in the same workshop as the plainer gold cup from Fritzdorf, Germany; the similarities between these finely crafted objects highlights the emergence of a series of regional but connected elites, choosing to define themselves by their possession of supra-regional ‘prestige objects’.

robust A statistical technique is said to be robust if it performs well even when the MODEL on which it is based does not hold for the DATA being considered. For example, although Wenban-Smith’s

use of DISCRIMINANT ANALYSIS at BOXGROVE was

based on assumptions about the VARIABLES which did not hold in practice, it performed well and gave useful results. Discriminant analysis can be said to be robust in this respect. Robustness is a desirable property, but difficult to study because there are many different ways in which data can depart from a model.

Rocca San Silvestro Situated in a hill overlooking the coastal plain of western Tuscany near the town of Campiglia Marittima, Rocca San Silvestro is a remarkably well-preserved 11thto 13th-century mining village. The greater part of the village was excavated between 1984 and 1993, and a systematic survey was made of mines in its environs. The excavations revealed a highly controlled feudal operation, managed for the Pisans by a local family occupying the small rocca (fortified tower). A romanesque church with a compact graveyard containing hundreds of burials was situated beside a piazza on the north side of the rocca. Well-built, two-floor dwellings gathered within the walls, around the contours on the east side of the hill. The communal olive press was found at the northern extent of the dwellings. Copper, lead and bronze were worked on the western side of the hill, each within its own enclosure. Silver for coinage was extracted here too. Iron, by contrast, was worked in a forge immediately outside the south gate of the village. Twenty-metre-deep shafts for the extraction of the minerals were excavated in the valley below. By AD 1350 the large village had been deserted, as the Pisans sought new, richer mineral sources in Sardinia.

Roc de Combe Sited on a tributary of the Dordogne, the cave/shelter of Roc de Combe is probably the only known site with reliable interstratification of CHÂTELPERRONIAN and AURIGNACIAN deposits. In a sequence from the

MOUSTERIAN through to GRAVETTIAN/Upper

Périgordian, the basal layer dating to the Upper Palaeolithic (layer 10) is fragmentary, but layers 9 and 7 are clearly Early Aurignacian, while layer 8 is clearly Châtelperronian. Given the now prevailing view that the Châtelperronian was the indigenous product of NEANDERTHALS, whereas the Aurignacian is intrusive, this site gives conclu-

sive evidence that ANATOMICALLY MODERN

HUMANS and Neanderthals coexisted in Western Europe for some time. Unfortunately, it is difficult to tell exactly how long this coexistence lasted.

Roc de Sers Upper Palaeolithic rockshelter in Charente, France, in which blocks of carved limestone depicting animals such as ibex, horses and bison (0.30–0.70 m tall) were found during the 1920s. The most famous block depicts two ibexes facing each other, their body outlines and curved horns boldly delineated in deep relief. Like the reliefs at the comparable site of ANGLES-SUR- L’ANGLIN the sculptures were originally painted; unlike the works found at that site, they were carved on blocks already detached from the cave wall, and were apparently set up to run as a single decorated frieze around the walls of the shelter. The Solutrean archaeological material found in the cave suggests that the sculptures may date from some time after 20,000 BC.

Rose Cottage Cave MSA (Middle Stone Age) cave site in the Orange Free State, South Africa, located a few kilometres east of Ladybrand. First excavated between 1943 and 1946 by B.D. Malan, the 7 m deep succession of deposits has been a matter of controversy for most of the intervening time. New excavations and reassessment of Malan’s records and material by L. Wadley have done much to clarify the situation. The succession commences with a pre-HOWIESON’S POORT expression of the MSA, followed by classic Howieson’s Poort, possibly divisible for the first time into two or three phases, followed by a variant MSA persisting to between 27,000 and 20,000 uncal BP, and anticipating, in its later stages, the ensuing Robberg industry (13,360–9250 uncal BP). The succession concludes with Oakhurst/Albany levels (9250–8380 uncal BP) and typical WILTON material. Associated charcoals indicate a shift from grass and heathland in the Late Pleistocene to grass, scrub and woodland in the Holocene.

Rössen Early Neolithic culture of central and southern Germany characterized by dark, highly polished pottery, some plain and some decorated with geometric motifs such as diamonds or zigzags, and a stone industry including shoe-last celts and disc bracelets. This stone industry is closely related to the earlier LINEARBANDKERAMIK culture, the first farming culture of the region. Rössen material succeeds the LBK, and may be partially contemporaneous with the Stichbandkeramik (SBK see

STROKE-ORNAMENTED WARE), another LBK

development, in south-west Germany. It persists longer than the SBK, and so is also a contemporary of early Michelsberg (the principal ‘middle Neolithic’ culture of the region). A notable difference between the Rössen and the LBK in most areas is the layout of the houses: the LBK houses are long rectangular/trapezoidal whereas Rössen examples have a less regular shape and tend to be squarish. At the late Rössen settlement of Berry-au-Bac, for example, a (probably defensive) ditch and inner palisade mark out an area of 2–3 ha, within which stand four timber buildings, the largest of which is 20 m long by 10 m wide, with deep postholes and foundation trenches. At a few Rössen sites in Germany, however, the longhouses are of a notably long, trapezoidal shape that is much more closely related to earlier LBK forms.

Rouffignac Deep cave apparently embellished with Magdalenian engravings and black-outline drawings, situated near Les Eyzies, France. Unusually, the cave is dominated by representations of mammoth (c.150) and there are no deer or oxen; it also has a unique frieze of large rhinoceros.

Royal Domain (ch’i, chi) Geographical area under the direct control of the kings of Chou, in the feudal-like administrative set-up which was established in China in WESTERN CHOU times (1122–771 BC; see CHINA 2). The exact nature and extent of the Royal Domain is a matter for debate: some rather fanciful views allege that the vast size of the ‘royal domain’, as compared to the ‘princely states’, arose towards the close of the EASTERN CHOU era (771–255 BC) and in the early centuries of Western HAN (206 BCAD 24). These views still tend to temper most reconstructions of the past (see Creel 1970: 363–6), despite the increasing array of relevant archaeological evidence (see

Rudna Glava Copper mine of the 5th millennium BC in northeast Serbia. Rudna Glava is the most intensively investigated early mining site in the central Balkans – 30 or so shafts have been excavated – and the site has helped to prove the autonomy and scale of copper metallurgy in the region. The ore (malachite and azurite) was extracted from horizontal and vertical shafts (up to 20 m deep) using antler picks and stone pounds to break up deposits which may already have been weakened by fire-heating and sudden dowsing with water. The mines have only been dated indirectly

Archaeological investigations conducted during the 1950s and 1960s revealed seven stratigraphic zones. The bottom three strata contained cultural material dating from the Early to Late Archaic periods. Three radiocarbon dates calibrated between 4030 and 4360 BC were associated with a Middle Archaic ‘Morrow Mountain’ component (the Morrow Mountain phase (c.5300–3500 BC), identified by distinctive stemmed projectile points, was first defined at sites in the North Carolina piedmont). Late Archaic artefacts resembling those found at the well-known Tennessee River shell middens were found above the Middle Archaic stratum. The upper four strata contained ceramic and lithic artefacts dating to the

Sabz, Tepe Neolithic settlement site in the Kuzistan region of southwestern Iran that has given its name to the Sabz phase, dating to the late 6th millennium BC. The earliest Sabz assemblages show great continuity with the preceding Muhammad Jaffar phase, in terms of the ceramics and microlithic tools, as well as the remains of plastered mud-brick houses, built on stone foundations (with the addition, in the Sabz phase, of party-walls made of tauf). The painted buff Sabz ware is closely related to the Susiana A–D ceramic sequence defined at Neolithic SUSA. It has been suggested that the scale of flax production at Tepe Sabz may be an indication of the introduction of irrigation (Hole et al. 1965).

It is in the upland regions that Saharan rock art has been found: the Tassili-n- Ajjer/Hoggar region in southern Algeria (the Tassili covering the northern half of the upland massif, the Hoggar covering the southern half, see map 1) and its offshoot the Tadrart Acacus in western Libya. Other major sites include Adrar des Iforas (across the Mali/Algeria border), Air (in Niger), Tibesti and Ennedi (in Chad) and JEBEL UWEINAT (on the borders of Libya, Egypt and Sudan). There is also rock art in the lower-lying Fezzan area.

Several tens of thousands of paintings and engravings have now been registered, even though many regions are still poorly explored. Although many 19th-century European explorers reported

502 SAHARAN ROCK ART

seeing rock paintings and drawings in their travels across the Sahara, the first systematic studies by archaeologists were those of G.-B.-M. Flamand (1921) and Raymond Vaufrey (1939) in the western desert, and Leo Frobenius (1937) and Paolo Graziosi (1937; 1939; 1942) in the eastern desert. These studies indicated a broad chronological division between an earlier style (showing game and stock such as cattle), which is assumed to be prehistoric in date, and a later style (with scenes of horses, chariots and camels) which is presumed to reflect contact between the Saharan population and peoples such as the Egyptians, although no absolute dating evidence was available for either.

In the 1950s and 1960s, efforts were made by Henri Lhote (1958; 1965) and F. Mori (1965) to refine and date the development of the art. Developmental stages in the material were established by detailed typological studies, based on analyses of style and technique augmented by inferences from patina, overlay, and archaeological and historical correlations, and occupation deposits in decorated caves or rock shelters were excavated for material for radiocarbon dates: the latter could at least indicate a general date for the paintings by association or, better still, date them from the occurrence in the occupation deposits of objects decorated in the same style, or even pieces of the rock art that had flaked off the walls into the deposits.

These studies indicated five main styles/periods:

(1) Big Game, with incised pictographs of animals such as elephant, buffalo, crocodile, hippopotamus, giraffe and rhinoceros, a savannah fauna indicating a period of much greater moisture in the Sahara than today; (2) Round Heads – paintings of roundheaded humans; (3) Pastoral or Cattle – paintings and engravings of humans herding cattle; (4) Equid

– incised and painted scenes with horses; and (5) Camel – incised and painted scenes with camels. Radiocarbon dates in the Libyan Tadrart Acacus indicated dates of c.7000 uncal BP for the Round Head style and c.5000 uncal BP for the Pastoral style (Mori 1965). The Big Game motifs were variously regarded as Palaeolithic or Mesolithic in date. The Horse and Camel styles also included depictions of chariots and other motifs indicating contact with the Egyptian and classical civilizations.

The validity of these typological sequences, however, is now very doubtful. Muzzolini, in particular, has argued in a series of studies, firstly, that the Big Game motifs (also termed ‘Bubaline’) form a style or school of designs, not an initial phase of rock art, secondly that they were in fact contemporary with the Pastoral or Cattle motif along with many of the

‘Round Head’ paintings, and thirdly, that the main corpus of early rock art in general was contemporary with the transition from hunting to herding in the Sahara (Muzzolini 1986, 1990, 1991, 1993). The most recent radiocarbon dates indicate that cattle and sheep herding had appeared in the Sahara by 5000 or 5500 BC. The Equid and Camel motifs are certainly late in the rock art tradition, but again there are many indications of contemporaneity, and there is general agreement that most of them probably date from about 1500 BC onwards, reflecting contact between the Saharan peoples with Egypt and later also with the Phoenicians and Greeks (Muzzolini 1982a, 1982b).

Detailed studies of the Fezzan material by Le Quellec (1987) support Muzzolini’s arguments for regional diversity and stylistic mixing after about 4000 BC, rather than a long sequence of widespread styles beginning much earlier in the Holocene. In the Adrar des Ifroras in Mali, too, the Big Game and Pastoral motifs appear to be more or less contemporary, separated from a later set of pictographs indicative of horse and camel herding (Dupuy 1989, 1990). Dupuy (1992) links the two groups of material respectively with the ancestral peoples of present-day Fulani pastoralists and Tuareg conquerors.

The period of the transition from hunting to herding in the Sahara was characterized by significant climatic fluctuations, with increasing aridity over time. Rather than seeing the rock art as literal representations of hunting or herding, as before, therefore, Le Quellec (1987), Smith (1993) and Muzzolini (1995) have suggested that most of it is probably best understood in terms of the changing ideologies of Saharan peoples at a time of major transformations in life-styles in response to environmental change. They draw parallels with the role of rock art (both the art of making it, and the completed ‘text’) in the complex ideologies of the Kalahari San (Lewis-Williams 1981, 1982, 1983), in which it operates as encoded messages in activities such as initiation rites. Smith suggests that the animals drawn acted as metaphorical intermediaries between humans and the spirit world, interpreted by specialist SHAMANS. The analysis of the Saharan rock art in such terms promises to yield considerable insights into the social and cognitive transformations experienced by societies as they changed from hunting to herding. ACCELERATOR MASS SPECTROMETRY dating applied to pigments also offers the hope of considerable refinements in the chronology of the art.

Sa Huynh Prehistoric urnfield cemetery in coastal Vietnam, discovered in 1909. Excavations led to the recovery of 120 large lidded jars, disposed in groups, which contained cremated human remains. Numerous other such sites have been found, all concentrated in the coastal tract of central and southern Vietnam (e.g. Tam My, where the cremated bones of the dead were placed in large lidded jars, and the grave goods included iron spearheads, knives and sickles, as well as bronzes). Calibrated radiocarbon dates fall within the second

half of the 1st millennium BC, and the grave goods include iron spearheads, knives and sickles as well as bronze spearheads and bells and exotic stone jewellery. Double animal-headed stone pendants from this area are paralleled in DONG SON, Philippine and central Thai contexts. The mortuary ritual is so unlike any other in prehistoric Southeast Asia that there is a serious case for considering the Sa Huynh culture as intrusive. The sites are located in the same region as the later CHAM polities, and could well have been ancestral to the Austronesian-speaking Chams themselves.

St Gall Abbey Abbey in Switzerland which was the first monastic site to be planned in detail. The plan comprised a schematic red-ink drawing composed of five separate pieces amounting to an overall size of 0.77 × 1.12 m., which is now in the Stiftsbibliothek (Ms. 1092) of the Abbey of St Gall. This drawing depicts the plan of a monastery at c.AD 820, and a dedication indicates that it was a specific building project made at the request of the Abbot Gozbert of St Gall.

The plan has been the subject of much debate because Walter Horn proposed that it was a paradigm for all early medieval monasteries (Horn and Born 1979); Jacobsen 1992). It depicts a medieval monastic lay-out, showing an abbey-church with an attached cloister, surrounded by a variety of service and other buildings. Excavations at St Gall indicate that the plan was never realized, whereas excavations at nearby Mittelzell, Reichenau suggest that the draughtsman was using local architectural ideas already developed there (Zettler 1990).

France, of the Middle Neolothic CHASSÉEN complex. A palisade and a series of deep ditches mark off the promontory on which the site is located, and may form part of an interrupted ditch system. Like other Chasséen sites in the region (e.g. VILLENEUVE-TOLOSANE), the structural remains of the interior of Saint-Michel-du-Touch are dominated by multiple cobble structures, which were originally assumed to be hut bases but may represent large food-processing or cooking hearths. There are also pits and graves, most notably a double burial within a massive rectangular pit (7.4 m × 4 m) filled with cobbles and with pottery. The pottery includes two decorated VASE SUPPORTS (a pottery type diagnostic of the Chasséen complex), decorated with ladder and elongated triangle motifs. The honey-coloured flint and the obsidian blade found in the grave are also typical of the French Middle Neolithic, for it was in this period that trade or exchange systems first developed extensively and ‘exotic’ materials were introduced. The site was probably in use for over a millennium, perhaps between 4900 and 3200 BC.

Sais (Sa el-Hagar) Town-site in the Egyptian western Delta, dating principally to the 8th–6th centuries BC, when it was the provincial capital of the 5th nome of Lower Egypt and the seat of the 24thand 26th-dynasty rulers. The remains of the tell have been largely destroyed by local farmers removing archaeological deposits for use as agricultural fertilizer, and there appear to be no surviving remains earlier than the 11th century BC.

Salado Late prehistoric culture in the American Southwest, primarily in southeastern Arizona and southern New Mexico. The geographical range and temporal span (c.AD 1280–1500) are defined by the occurrence of Roosevelt Red Ware ceramics (including Pinto, Gila and Tonto polychrome); associated cultural characteristics include adobe and rock-adobe construction of PUEBLOS, PLATFORM MOUNDS and walled compounds.

There are three models with which the Salado can be interpreted. The first and oldest model regards it as a distinct culture formed late in prehistory either by the merging of ANASAZI and MOGOLLON elements or by a specialized adaptation of the HOHOKAM. The second interprets Salado not as a culture but as a multi-ethnic phenomenon resulting from the demographic upheaval of the abandonment of the Colorado Plateau, rapid population increase in the central Arizona mountains, and expansion out of Chihuahua into southern New Mexico and Arizona. The Lake Roosevelt/Tonto Basin region, considered to be the Salado heartland in the first model, reflects the multi-ethnic use of the area. Ethnic co-residence during Salado times is to be seen in the mixture of architectural conventions: cliff dwellings with rectangular and T-shaped doors; rambling checkerboard-style, cobbled masonry pueblos; platform mounds; and walled compounds. The third model interprets the weak unity of Salado as indicative of a cult or ideological system, cross-cutting different ethnic groups.
