Stone Structures

This paper describes a large area of stone-built ruins in northern Tanzania which has so far only been briefly excavated, but which is likely to prove to be a key site in the study of the Iron Age in East Africa. In addition to numerous massive stone circles, terraces and cairns, there are extensive systems of fields and enclosures defined with lines of stones. Excavations carried out in 1964 and 1966 have shown that the small terrace-platforms on the hillsides and the stone circles on the flatter land in the valley were occupied at different periods and by different peoples whose pottery is readily distinguishable. Radiocarbon dates suggest that the terrace sites on the hillsides were occupied during the first millennium A.D., and that the stone circles on the lower slopes in the valley were occupied during the fifteenth century A.D. The purpose of the numerous large and well-built cairns is not yet known, but it appears that they were not burial monuments. No evidence has been found that any of the stone structures were built or occupied by immigrants from outside Africa.It has not yet been possible to link the systems of fields and enclosures to the hillside terrace-platforms or to the stone circles. A close examination of the main area of fields and of low-level aerial photographs has not produced any evidence that the fields were irrigated, a fact which raises important agricultural and climatic problems in an area which has an average rainfall of less than 380 mm. (15 inches).The general picture of Engaruka which emerges is of an area which was occupied by different peoples at different times over a period of at least a thousand years. The stone structures which these different peoples built have accumulated to give the impression that there was once a very large population living in the area; in fact it is possible that this population was always less than 4,000 people at any one time.

The excavation was undertaken with the funding and support of Grampian Regional Council to test hypotheses relating to the interpretation of cropmark pit circles: were they Neolithic or Bronze Age ceremonial or funerary structures, or were they Iron Age houses, and to what extent could the two classifications be differentiated on aerial photographs? The excavation revealed the remains of four circles (between 8.5 m and 11.5 m in diameter) of large post- holes, fence lines (one with a gate), and many other pits and post-holes. Radiocarbon dates place the post circles late in the first millennium BC uncal. The pit circles may be interpreted as the main structural elements of four substantial round houses, two of which burned down. Flint tools of the Mesolithic period were recovered.

Power And Influence

The suggestions put forward in this paper may be summarized as follows. The linguistic, cultural and to some extent physical ancestors of the modern Bantu people south of the Zambezi, including the Shona, arrived in Rhodesia in the early part of the first millennium a.d. The B1 culture was not introduced by Shona migrants arriving in the eleventh century, but was a local development of the already existing Shona Iron Age A, attributable perhaps to prosperity gained from the gold trade. The B1 culture should not in fact be regarded as a separate culture from the A, that later fused with it, but as a variant of it, which because of the power and influence of those who developed and practised it eventually spread over a large area and became a common factor in the various local Shona cultures that had diverged, and continued to diverge, in the course of time.

The fourth radiocarbon list contains many new and important dates. Only isolated readings are still available from West Africa, but some later Iron Age sites have recently been dated. The first samples for the Kenya Highlands date food production in that region to the first millennium b.c., while important dates from Uganda confirm the traditional datings of Bigo and Bweyerore. Samples from Kilwa on the Tanzanian coast are somewhat at variance with other dating evidence.Dates for the Angola Iron Age range between a.d. 760 and the fifteenth century, while the Leopard's Kopje industry of Rhodesia has been dated for the first time.The list is completed with many isolated dates from all parts of the subcontinent.

The complete excavation of a post-defined Neolithic enclosure took place in 1979 and 1980 in advance of the construction of a gas compressor station for the British Gas Corporation. The enclosure appeared to have been constructed in two parts. There was little evidence for any associated activity except for a pit in the north half. Three charcoal samples from the post-holes produced radiocarbon dates in the range 3930-3390 cal BC. A small sample of a scatter of pits visible on aerial photographs was also excavated. Six penannular ring-ditch houses dating to the mid first millennium BC were also investigated. The houses were of the broad ring-ditch type with internal ring beam support. Other features included six-post structures and crescent-shaped hollows which might be the truncated remains of further house sites. There was little horizontal stratigraphy. The project was arranged and funded by Historic Scotland and its predecessor departments, with a contribution by British Gas.

Historical Sequences

Obsidian hydration dating has been successfully applied to East African archaeological sites. Chemical sourcing of obsidian artefacts has documented long-distance movement of obsidian from the Central Rift valley. A date in the ninth or eighth century b.c. has been obtained for iron objects in the Er Renk District of the Southern Sudan. Tentative culture-historical sequences are available from excavations around the Sudd and in the Lake Besaka region of Ethiopia. Archaeological research has begun in the interior of Somalia. In northern Kenya, claims that Namoratunga II is an archaeo-astronomical site have been challenged. Excavations at Mumba-Höhle and Nasera have shed new light on the transition from the Middle to Later Stone Age in northern Tanzania perhaps 20,000 to 30,000 years ago. Knowledge of the Elmenteitan Tradition has been considerably advanced by excavations in south-western Kenya. Iron-smelting furnaces with finger-decorated bricks have been discovered in south-eastern Kenya, though not yet dated. New dates falling in the last few centuries have caused first millennium a.d. dates obtained previously for Engaruka to be rejected. Excavations at several sites on the East African coast indicate that the beginnings of coastal occupation from the Lamu archipelago to Mozambique fall in the ninth century a.d. In Malawi the Shire Highlands seem to have been settled around the tenth century a.d. Investigations of large smelting-furnaces in central Malawi indicate that they were used as concentrators of poor-quality iron ore. Excavations in rock-shelters on the southern edge of the Copperbelt have produced a culture-historical sequence spanning the last 18,000 years. The western stream of the Early Iron Age was established in the Upper Zambezi valley by about the mid fifth century a.d.

This article surveys the latest archaeological research and dating results for West Africa. For the Iron Age, recent fieldwork has been spread widely: especially noteworthy is that bearing on the history of ancient Ghana and Mali. Work on the Late Stone Age appears by contrast to have been rather patchy lately, although various palaeoecological researches continue to improve our understanding of the changing environments affecting West African populations over the last 10,000 years. In south-central Niger, moreover, remains of copper-smelting by a stone-using community are dated to around 2000 B.C. From the same region, as also from northern Ghana, comes further evidence for the inception of the Iron Age during the first millennium b.c.The article is prefaced by some critical comments on the citing and interpretation of radiocarbon datings in historical discussions, and on the meaning of ‘corrected’ and ‘calendar dates’.

Iron Working

Several significant trends are noted in the recent radiocarbon dates from North and West Africa. The early Khartoum Neolithic dates from Nabta Playa of the seventh millennium B.C. and the thermoluminescence dates from the Badarian of the sixth millennium, would appear to have redressed the balance for the time being in favour of the Nile Valley in the argument as to whether agriculture in the Nile Valley predates that in the Sahara. A more cautious approach might be to say that these dates emphasize the need for far more securely dated evidence before conclusions are drawn on this complicated, and often emotional, problem. The presence of sorghum in the first quarter of the first millennium A.D. at Jebel et Tomat provides the earliest direct evidence for this key African agricultural staple. Many interesting very late Stone Age dates have come from West Africa and indicate the contemporaneity of stone and iron using communities throughout the first millennium A.D. in certain remote areas. The dates of the Senegambia megaliths are clearly falling within the first millennium A.D. Dates for iron working in both Nigeria and Ghana are confirming that iron technology was well established by the first half of the first millennium A.D. The dates from Ife and elsewhere in Nigeria are clearly indicating that the ‘classic’ terracotta period, and also the pottery pavements, belong to the twelfth to the fourteenth centuries. The state of research in North and West Africa reflects the well-known, but too often neglected, archaeological truism that researchers find what they are looking for and rarely more; the Iron Age emphasis in West Africa, and the Paleolithic-Epipaleolithic concentration in the francophone lands. Presumed general trends in these areas, particularly conclusions comparing development in North and West Africa, should be examined carefully for underlying sampling biases of an ideological as well as of a geographical nature.

Structured Approach

Hebridean sites of the coastal sand cliffs and associated machair, or sandy plain have been known for many years. Artefacts and ecofacts of various types have long been collected from archaeological sites in the eroding sand-cliffs of the machairs of the Outer Hebrides. Early in 1983, personnel of the then Central Excavation Unit of Historic Scotland's predecessor revisited very nearly all of the coastal archaeological sites then known in the Long Isle, with the specific task of identifying those at immediate threat from coastal erosion and of assessing the feasibility of their excavation or preservation. Some 32 sites were seen to be undergoing active erosion; at nine of them preservation was not being pursued and excavation was feasible. These sites were of two morphotypes: sites exposed in roughly vertical sand-cliffs and sites exposed over relatively large horzontal areas of sand deflation. It was decided to examine one sand-cliff site along its exposed face. The site selected was Balelone in North Uist, its excavation designed to explore both the problems associated with the excavation of deep midden sites with complex stratigraphy and the not-inconsiderable problems of excavation in sand. In the light of the Balelone trial excavation, a new approach was called for. A structured approach aimed firstly at establishing the three-dimensional extent of the sites to be examined. Four sites were then sampled (the sand-cliff sites of Baleshare, on the island of the same name off the west coast of North Uist and Hornish Point, South Uist and the deflation sites of South Glendale, South Uist and Newtonferry, North Uist) within a rigorously-defined research framework.The machair sites were formed by sand accretion, facilitated by human activities ranging from construction to refuse disposal and cultivation. Their formation was intermittent and they underwent episodes of major erosion, isolating the sites from the landscape mass of the machair sands. Despite their apparent wealth of suitable material, the dating of Hebridean coastal sites presents special problems. The strategy here was to provide a dating framework for the sequences on each site, from which the dates of archaeological significant structures and events could then be arrived at by extrapolation. Preliminary dates from the earliest and latest strata at Balelone spanned such a small period that a First Millennium BC date-range could be assigned. At Baleshare, the deposits investigated were chiefly later Bronze Age; following abandonment (roughly 200 radiocarbon years) of the Period I cultivated soil Period II represented extensive, manured, cultivated fields in the vicinity of a settlement now lost to the sea. As Period II went on. the settlement seems to have moved closer to the excavated area. After another hiatus of a minimum of 350 radiocarbon years, there were further cultivated plots and associated settlement of Iron Age date (Period III). By contrast, the site at Hornish Point (including successive wheelhouses and associated cultivation areas) is considered to be all of one - dynamic, Iron Age - period, lasting some 300 radiocarbon years (with potentially earlier structures unexcavated). A post-medieval blackhouse of characteristic Lewisian form had been cut into the settlement mound. The three dates from Newtonferry suggest that some Early Medieval activity took place at the site, while the bulk of the deposits date from the thirteenth-fourteenth centuries AD. At South Glendale, the radiocarbon dates indicate occupation sometime between the thirteenth and fifteenth centuries AD; stratigraphically lower, fragmented and truncated remains were prehistoric, probably early Bronze Age.

Research over the past five years or so indicates that in north-western and central Kenya and northern Tanzania pastoralism is much older than previously supposed. Radiocarbon dates from the central Rift valley and the Serengeti plains suggest the presence of domestic cattle by about the sixth millennium b.c. Early pottery traditions in the central Rift valley and around Lake Turkana have been more precisely identified. A continuing research project in the southern Sudan has revealed early pottery with possible northern affinities and rouletted pottery of the first as well as second millennia a.d. In north-western Tanzania, iron would still seem to have been smelted as early as the sixth century b.c. The use of iron, and perhaps of rouletted ware, by pastoral peoples in central Kenya is now dated to the late first millennium a.d. In Malawi, food-production would still seem to have been introduced early in that millennium, but the introduction of cattle has now been dated to the third or fourth century a.d., some centuries earlier than had previously been supposed. In Zambia, the surprisingly early dates for Situmpa pottery have apparently been confirmed. On the east coast, excavations at Hafun, Mogadishu and Manda have enabled more precise dating of the periods during which these ancient ports flourished, while a comprehensive survey programme has refined our knowledge of monumental sites along the Kenya coast.

Marine Protein

Stable isotope measurements and radiocarbon dates on 54 burials from northern Scotland document trends in marine protein consumption from the late Iron Age to the end of the Middle Ages. They illuminate how local environmental and cultural contingencies interrelated with a pan-European trend towards more intensive fishing around the end of the first millennium AD. Little use was made of marine foods in late Iron Age Orkney despite its maritime setting. Significant fish consumption appeared in the Viking Age (ninth to eleventh centuries AD), first in the case of some men buried with grave-goods of Scandinavian style but soon among both sexes in ‘Christian’ burials. There was then a peak in marine protein consumption from approximately the eleventh to the fourteenth centuries AD, particularly among men, after which the importance of fish-eating returned to Viking Age levels. The causes of these developments probably entailed a complex relationship between ethnicity, gender, Christian fasting practices, population growth, long-range fish trade and environmental change.
