The Servilia tomb: an architecturally and pictorially important Roman building

One hundred and eleven samples from the important Servilia Roman tomb have been analysed for the first time by Raman spectroscopy, resulting in a complete characterisation of the pigment palette used for its remarkable wall paintings: 73 different pigment mixtures have been identified for the composition of its 11 colours and their tonalities. Dyer’s weld, an ancient organic yellow pigment, which was described by Vitruvius, has been identified and characterised for the first time in Roman wall paintings. Distinctive Raman spectroscopic signals which differentiate between haematite and caput mortuum (a violet colour from haematite which has been subjected to thermal treatment) are also reported. The use of the very expensive lazurite for a balance relates the importance of this otherwise ordinary instrument with psychostasia (the human soul weighing process) and is not found elsewhere in the tomb. The distribution of white minerals alone or in admixture is not related to any particular colouring pigment or figure; this possibly indicates that there was no specific use for each white mineral and that several craftsmen worked on the paintings, perhaps in different periods, or that the frescoes have been subjected to unrecorded restoration. We conclude that Raman spectroscopy is a valuable analytical technique for the unambiguous identification of mixtures of both organic and inorganic compounds, to study the degree of mineral crystallinity and for identifying treatment. These data are relevant for the holistic interpretation of the artwork in its historical, economical and social context.

The Quadrivium of Online Public Consultation: Policy,Culture, Resources,Technology

Concerned by declining interest, trust, and participation by citizens in democratic politics, governments and political institutions worldwide are turning to the internet in attempts to revitalise democracy through online public consultation and citizen participation, referred to as e-democracy or ‘government 2.0’. This paper reports research into the planning and conduct of a series of online public consultation trials launched by the Australian federal government in late 2008, and it compares and contrasts Australian experiences with international e-democracy developments, including the Obama presidential campaign and findings of the Digital Dialogues review of online technologies to enhance citizen engagement in the UK, the UK Power of Information Task Force review, and experiments conducted as part of the MIT Deliberatorium. This paper presents qualitative analysis of findings in 10 areas, which it argues can be further grouped into four main areas of management focus of which technology, often the major topic of discussion, is important but less significant than policy, culture and resources.     

Hydrogeological Modelling of Water-Level Changes in an Area of Archaeological Significance: A Case Study from Flag Fen,Cambridgeshire, UK

Concern exists regarding the long-term viability of the internationally important archaeological remains of the Flag Fen site near Peterborough. This paper describes a hydrogeological numerical groundwater model which has been used to understand the groundwater situation with regard to the archaeology, including drainage impacts, and also to explore future scenarios. Observed and modelled groundwater levels have been interpreted using three zones: the ‘dry’ zone 1 above the seasonal maximum water table; zone 2 of seasonal water table fluctuation; and a deeper zone 3 of permanent saturation. Archaeological wood is best preserved in Zone 3. Much of the Bronze Age wooden structure is located within Zone 2 or above. The hydrological conditions are therefore not ideal for the long-term in situ preservation of the material. Groundwater modelling indicates that the main factor controlling groundwater levels in the area is artificial drainage. The approach would be applicable to other wet-preserved archaeological sites.     

Re-evaluating the Monitoring of the Shardlow Log Boat

Following the discovery of a Bronze Age log boat in Shardlow Quarry, Derbyshire in 2003, a scheme was devised to preserve this boat in situ. This included a monitoring programme to ensure that reducing conditions were maintained. This solution was agreed by the mineral planning authority Derbyshire County Council, with input and advice from English Heritage.

Monitoring lasted ten years, during which time gravel deposits surrounding the boat were extracted. The boat was protected from dewatering during this time by a clay cut-off, installed around the area containing the boat before extraction begun. After extraction the adjacent areas were backfilled with on-site soils and inert waste.

Data indicate that a reducing environment has been largely sustained during this period. Following careful and considered discussion, the monitoring programme ceased as there was unlikely to be further impacts to site hydrology, making additional data collection redundant.
