This is the first description of the prehistory of the coastal Congo, won by the author and his colleagues against considerable odds: war, exploitation by big business and, above all, by the entrenched assumption that this part of the world had no history to save. Here is a first glimpse of that history: 3300 years of prehistoric settlement, movement and change chronicled by radiocarbon dating and a new ceramic typology.

In this paper the author places the rock art of Uganda in context. It probably belongs to the Late Stone Age period to the Holocene and its symbolism may be interpreted in the light of later belief systems recorded amongst the historical Pygmy people. Pongo is the bark cloth used to make the distinctive loin cloths of men and aprons of women. Pongo are probably depicted in the rock art to evoke the fecundity of ndura, linking the real and supernatural within the Pygmy cosmos.

Thanks to a number of well-stratified sequences, the authors can offer a new history of clay image-making in West Africa. From the first known human occupation in the second millennium BC, the shaped clay figurines remain remarkably conservative, suggesting their use as offerings, toys or in games or some role rooted in domestic everyday life. Only in the late first millennium BC and in one area (Walasa) does a more formal art emerge in north-eastern Nigeria, a development contemporary with the famous Nok culture further south.

The exploratory investigation of two sites in Kenya throws new light on the transition from a ‘stone age’ to an ‘iron age’. The model of widespread cultural replacement by Bantu-speaking iron producers is questioned and instead the authors propose a long interaction with regional variations. In matters of lithics, ceramics, hunting, gathering, husbandry and cooking, East African people created local and eclectic packages of change between 1500BC and AD500.

Mali is a country with a rich history and diverse cultures. Its cultural heritage is, however, threatened by both the pillage of archaeological sites and illicit trade (ICOM 1995; Bedaux & Rowlands, this volunle). Looting has dramatically increased in recent years, especially in the Inland Delta of the Niger, and has obliged Malian authorities to take measures to counteract this destruction. Within the framework of a long-term Malian-Dutch cultural heritage programme, the Rijksmuseum voor Volkenkunde at Leiden recently initiated large-scale excavations in the Inland Niger Delta at Dia, in close cooperation with the Université du Mali, the Institut des Sciences Humaines and the Musée National du Mali in Bamako, the Mission Culturelle in Djenné, the Universities of Paris I and VI, the C.N.R.S., University College London and Leiden University. This excavation, financed principally by the Dutch Ministry of Foreign Affairs, started in 1998 and will continue until 2004. It is a continuation of previous international programmes of site survey and documentation in the Inland Niger Delta, which the Institut des Sciences Humaines in Bamako has co-ordinated over the past two decades (e.g. Raimbault & Sanogo 1991; Dembele et al. 1993; Togola 1996). An initial season of prospection was carried out in 1998 in the Inland Delta, following which the vicinity of Dia was chosen as the principal research zone for the project.
