Pollen has been studied from cesspits and other archaeological structures containing human faecal remains from different sites in northern Belgium, dating from the 12th to the 17th century. The results show that a large amount of information can be obtained by analysing pollen from such archaeological features. In addition, it is demonstrated that this information is largely complementary to the results obtained by the analysis of botanical macro-remains. The consumption of different food plants like herbs, spices and leafy vegetables, but also the use of honey, pharmaceutical plant use, and the use of peat fuel is reflected in the pollen assemblages from the studied archaeological structures. Most of this information cannot be obtained through the analysis of botanical macro-remains. [ABSTRACT FROM AUTHOR]

Frankincense, the oleogum resin from Boswellia sp., has been an early luxury good in both Western and Eastern societies and is particularly used in Christian funerary and liturgical rites. The scant grave goods in late medieval burials comprise laterally perforated pottery vessels which are usually filled with charcoal. They occur in most regions of western Europe and are interpreted as incense burners but have never been investigated with advanced analytical techniques. We herein present chemical and anthracological results on perforated funerary pots from 4 Wallonian sites dating to the 12–14th century AD. Chromatographic and mass spectrometric analysis of lipid extracts of the ancient residues and comparison with extracts from four Boswellia species clearly evidence the presence of degraded frankincense in the former, based on characteristic triterpenoids, viz. boswellic and tirucallic acids, and their myriad dehydrated and oxygenated derivatives. Cembrane-type diterpenoids indicate B. sacra (southern Arabia) and B. serrata (India) as possible botanical origins. Furthermore, traces of juniper and possibly pine tar demonstrate that small amounts of locally available fragrances were mixed with frankincense, most likely to reduce its cost. Additionally, markers of ruminant fats in one sample from a domestic context indicate that this vessel was used for food preparation. Anthracological analysis demonstrates that the charcoal was used as fuel only and that no fragrant wood species were burned. The chars derived from local woody plants and were most likely recovered from domestic fires. Furthermore, vessel recycling is indicated by both contextual and biomarker evidence. The results shed a new light on funerary practices in the Middle Ages and at the same time reveal useful insights into the chemistry of burned frankincense. The discovery of novel biomarkers, namely Δ2-boswellic acids and a series of polyunsaturated and aromatic hydrocarbons, demonstrates the high potential for organic chemical analyses of incense residues.

The material remains and environmental data recovered during a rescue excavation in 2002–03 in the castle of the new town of Middelburg-in-Flanders throw light on the site, region and landscape in wartime. The paper discusses the historical context at the turn of the 16th century, the excavation of the castle, the taphonomy of the chutes, the analysis of the artefacts and ecological data recovered from two garderobe chutes in the upper court, and concludes with a synthesis focussing on the interpretation of the excavated record in the historically attested natural and socio-economic disruption caused by the Spanish-Dutch War.
