A Raman spectroscopic study of glass trade beads excavated at Mapungubwe hill and K2, two archaeological sites in southern Africa,raises questions about the last occupation date of the hill

Thousands of glass trade beads were excavated over a 75 year period on Mapungubwe Hill and at K2, two archaeological sites in the Limpopo valley, South Africa. An assemblage of 175 beads that appeared to be different in shape, size and colour (red, yellow, green, blue, white, black, pink, plum) was studied with Raman scattering. At least seven different chromophores or pigments (lazurite, lead tin yellow type II, Ca/Pb arsenate, chromate, calcium antimonate, Fe–S “amber” and a spinel) have been identified. Pigment identification allows the recognition of specific productions and indicated that many of the pigments colouring the beads excavated on Mapungubwe hill were manufactured after the 13th century, confirming the presence of modern beads in the archaeological record, some dating from the 19th century. This date is in agreement with the last occupation date for the hill suggested by the earlier excavators and raises questions about the revision of this date to 1290 AD by archaeologists in the 1970’s.

Beyond Iron Age ‘towns’: Examining oppida as examples of low‐density urbanism

The question of whether Late Iron Age oppida in Europe were truly ‘urban’ has dominated debate over these sites since the nineteenth century. Oppida have been surprisingly absent from comparative urban studies, however, despite increasingly nuanced perspectives on the nature and diversity of the urban phenomenon. In particular, Roland Fletcher's implication that oppida might represent part of a broader alternative form of low‐density urbanism has been largely overlooked, by Iron Age scholars and urbanism specialists alike. With the complex nature of many oppida now becoming increasingly apparent, I suggest it is a pertinent time to assess Fletcher's claim and examine whether oppida can be convincingly compared to low‐density urbanism elsewhere in the world and, if so, what implications this might have for understanding Iron Age societies. This paper argues that oppida do indeed display aspects of low‐density urbanism and that this is likely to be due to the negotiated nature of power in Iron Age societies.
