Offa’s Dyke: a historiographical appraisal

Offa’s Dyke is one of the largest and best known, if rather less well understood, field monuments in Britain. Despite this, there have been very few primary studies of it. This article makes a critical examination of the principal bodies of work dealing with the dyke. It argues that in many respects our knowledge is less certain than is usually believed. In particular it discusses the time and labour necessary for the construction of the earthwork and it is suggested that it could have been constructed much more quickly, and with a much smaller workforce, than is generally supposed. More fundamentally, the purpose and function of Offa’s Dyke are considered, and it is argued that, in addition to any practical utility it may have had, the earthwork had important ideological significances that until recently have been largely neglected. Specifically, it is argued that the dyke was a manifestation of eighth-century Mercian royal ideology, intended to consolidate the power of the Mercian kingship, in the west midlands in particular and southern England more generally.     

A Rich Bell Beaker Burial from Wellington Quarry, Marden, Herefordshire

An intact Bell Beaker grave was discovered in February 1996 at Wellington Quarry, Marden, Herefordshire. The unmarked flat grave had no signs of a ditch or barrow, but may have been timber lined. It contained a tanged copper knife, a shale wristguard fragment, four barbed and tanged arrowheads, three arrowhead blanks, three flint knives, two triangular points or small daggers and four flint flakes. The adult male inhumation was accompanied by a complete, Maritime (AOO) Bell Beaker and may be dated to 2750–2500 BC (Late Neolithic). It belongs to Case's Group D. A notable feature of the grave goods is their different states of wear and completeness, varying from pristine to old, and including a fragment of a wristguard.     

The first record of a Maastrichtian ammonite from the Perth Basin,Western Australia,and its biostratigraphical significance

The first known ammonite from the Maastrichtian of the Perth Basin, a single, incomplete specimen of Grossouvrites gemmatus (Huppé, 1854), is described from core material from the Lancelin No. 1 borehole. Foraminiferal and nannoplankton evidence date the ammonite as middle Maastrichtian; its age is also assessed on the basis of dinoflagellate assemblages from this section, but these give a less precise dating. The position of the ammonite with respect to a mid-Maastrichtian disconformity, which probably extended along much of the Western Australian margin is discussed.     

The dry tank: development and disuse of water management infrastructure in the Anuradhapura hinterland,Sri Lanka

We identify and offer new explanations of change in water management infrastructure in the semi-arid urban hinterland of Anuradhapura, Sri Lanka between ca. 400 BC and AD 1800. Field stratigraphies and micromorphological analyses demonstrate that a complex water storage infrastructure was superimposed over time on intermittently occupied and cultivated naturally wetter areas, with some attempts in drier locations. Our chronological framework, based on optically stimulated luminescence (OSL) measurement, indicates that this infrastructure commenced sometime between 400 and 200 BC, continued after Anuradhapura reached its maximum extent, and largely went into disuse between AD 1100 and 1200. While the water management infrastructure was eventually abandoned, it was succeeded by small-scale subsistence cultivation as the primary activity on the landscape. Our findings have broader resonance with current debates on the timing of introduced ‘cultural packages’ together with their social and environmental impacts, production and symbolism in construction activities, persistent stresses and high magnitude disturbances in ‘collapse’, and the notion of post ‘collapse’ landscapes associated with the management of uncertain but essential resources in semi-arid environments.
