Heritage Week 2019: Public lecture on food in ancient Ireland

In Ireland, we have just started celebrating Heritage Week 2019. Heritage Week in Ireland is coordinated by the Heritage Council and is a part of European Heritage Days -- an initiative of the Council of Europe and the European Union. The main aim of European Heritage Days are to promote awareness of our built natural and cultural heritage, and to promote Europe's common cultural heritage. We celebrate for a whole week in Ireland, with more than 2000 events organised throughout the country.

This year, I will present a public lecture on my research into food in ancient Ireland. This is the keynote event hosted by TII for Heritage Week 2019, and the event will take place at the National Museum of Ireland. TII (Transport Infrastucture Ireland) is the largest procurer of archaeological services in Ireland, and they have overseen the excavation of hundreds of archaeological sites from which ancient food remains have been recovered. The event is free, but booking is required.

I will start by exploring how we investigate food in archaeology. Then, drawing upon my work at the UCD Bloom garden this summer, I will examine case studies from four periods, based largely upon evidence from TII excavations: early settlers (Mesolithic), first farmers (Neolithic), medieval traders (medieval) and industrial society (post-medieval). Check out the Bloom garden website for more information on the case studies. If you are interested in reading even more, I have published widely on ancient food, so check out my publications.

As well as the public lecture, there will be an associated pop-up exhibition at the National Museum of Ireland, displaying the TII site reconstruction drawings that we featured at the UCD Bloom Garden, as well as replica artefacts relating to ancient food production. More information here.

New research project: Ireland’s food culture in the 16th and 17th centuries

I am very excited about my role in a new research project that started at the beginning of this month. The project is taking a multi-disciplinary approach to exploring what was on the dinner table before the arrival of the potato into Ireland. I am a Project Partner in in the five-year project, which was awarded €1.5 million funding from the ERC (European Research Council). The project is entitled “Food, Culture and Identity in Ireland, 1550–1650” (FOODCULT) and is led by a historian, Dr Susan Flavin (Trinity College Dublin), who is bringing together historians, archaeologists and scientists to investigate what was eaten, where, why and by whom, at a level never before attempted in Europe (McClatchie, in press).
The Irish diet underwent significant changes during the 16th and 17th centuries, particularly at the dining tables of the elites, reflecting changes in both locally produced and imported foods. Dr Flavin has undertaken extensive research into historical evidence for food in early modern Ireland (Flavin 2014). During this period of political and cultural change, she has highlighted the important role that food and drink played in constructing and maintaining social identities. This was a time when trade was booming, and there was also movement of peoples into Ireland from neighbouring countries, such as England, Scotland, Wales, France and the Netherlands. During this dynamic period, a wide range of imported luxury foods were enjoyed in the homes of elites, including sugar, turkeys, pineapples and artichokes. Flavin has also revealed how new ways of ‘civilised’ eating and drinking came to be accepted by some individuals, including in the lower classes of society. Written records of consumption from this period focus mainly on Ireland’s wealthy households, however, and offer fewer details of the average diet.

The FOODCULT project is addressing this issue by undertaking a detailed investigation of archaeological evidence, which can provide insights across a greater variety of social contexts. In recent decades, many archaeological excavations across Ireland have unearthed the actual remains of foods – often comprising charred seeds and animal bone – and food-related objects. As part of the FOODCULT project, my team at UCD School of Archaeology will explore a variety of datasets – archaeobotanical, zooarchaeological and artefact data from completed excavations – to develop new understandings of food preferences across time and space. The UCD team will work closely with members of the wider project team, comprising historians, environmental archaeologists, isotope analysts, residue analysts and data modellers from other institutions in Europe. This multi-disciplinary approach will enable an unprecedented level of investigation into diet and food culture in 16th and 17th century Ireland, allowing the team to map social, regional and temporal patterns, and provide new insights into broader societal change during this important time in Ireland’s history.

Environmental conference at Aarhus

I am in Aarhus, Denmark this week, participating in the annual conference of the Association for Environmental Archaeology. The AEA is a wonderful organisation, bringing researchers together to explore human interactions with past environments.

I am presenting a poster at the conference on plant remains from a Late Mesolithic lakeside platform. Derragh Island is located at the edge of Lough Kinale in central Ireland. The site contained habitation deposits and features, knapping debris and peat sediments, with evidence for several phases of use and abandonment. Exceptionally good waterlogged preservation was encountered. A wide variety of environmental analyses was undertaken, several of which have just been published by the Irish Quaternary Association (IQUA). Analyses included plant macro-remains, animal bone, wood charcoal, pollen, insects, peat stratigraphy, geomorphology and sediments. 

My poster is focused on the unusual discovery of a large cache of water-lily seeds. A wide range of plant species was recorded at Derragh, including hazelnut shell, yellow-water lily seeds and lesser celandine tubers. A very large deposit of water-lily seeds within a hollow may reflect processing of these seeds for consumption. Perhaps the seeds were being fermented before being dried, dehusked, winnowed, parched, ground and consumed. The poster explores the evidence from Derragh in the wider context of plant processing from Mesolithic Ireland and beyond.

Conference: The Role of Crops in Irish Farm History

I am a member of the Agricultural History Society of Ireland (AHSI), which is open to all with an interest in the history of agriculture and food in Ireland. We are a diverse group from many different backgrounds, including farmers, archaeologists, historians, agricultural advisers, palaeoecologists and social scientists. Our members range from established academics to students to the interested public. The AHSI organises regular conferences, as well as field-outings to places associated with farming and food.

The next AHSI conference will take place on 10 November at the Helen Roe Theatre, RSAI, 63 Merrion Square, Dublin 2. The topic is "The Role of Crops in Irish Farm History".  I will be speaking on my research into prehistoric cereals in Ireland, tracking the introduction of cereals into Ireland around 6000 years ago and exploring how agriculture changed over time.

Flotation: introducing the wheelie-bin tank

During archaeological excavations, we often collect soil samples from different deposits to check if any plant remains are present. Plant macro-remains must be extracted from the soil sample before they are identified. The flotation technique is used to process bulk soil samples containing charred plant macro-remains. Differences in the density of organic and inorganic material mean that flotation is useful method for separating the two, because the specific gravity of water lies between that of organic and inorganic material. Flotation involves the placing of a soil sample into a container, then immersing the sample in water. When agitated, organic material (such as charred plant remains) is released from the soil matrix and floats to the surface, or is suspended in the water, whereas inorganic material sinks to the bottom of the container.

We often use mechanised flotation systems or flotation tanks for efficient processing of soil samples. This summer, I was thrilled to use a new type of system: the converted wheelie bin. This flotation system was created by team members of a Serbian excavation project over the past few years, and I was delighted to join the team in July 2018. We undertook excavations
 at the fortified centre of Gradiste Idjos, working with an international team from Serbia, the UK and beyond. You can find out more about the project here

One of my roles on the project this summer was to oversee flotation of soil samples using the wheelie-bin system. It is very simple, but very clever. Water is pumped into the base of the bin through an inlet. A fine mesh (1 mm) is suspended just below the surface of the water in the bin, and the soil sample is placed onto the mesh. As the soil is disaggregated in the flow of water, the organic material floats to the surface and is then caught by a smaller sieve (minimum 0,3 mm mesh) at a run-off point, cut into the top of the wheelie bin. The residue does not float, remaining on the 1 mm mesh. The wheelie bin proved to be an excellent innovation and could be moved around with little effort. I am very much looking forward to using it again next summer!

Gordon Hillman: a pioneer in archaeobotany

Gordon Hillman, photographed by his daughter
It was with great sadness that the archaeobotany community learned of the passing of Gordon Hillman earlier this month. Gordon was a pioneer in archaeobotany. He was a leading expert in the identification of ancient remains, and I was lucky enough to spend time in front of the microscope with Gordon learning about cereal identifications. I still use my notes from those sessions today.

But Gordon did much more than this. He undertook extensive fieldwork in south-east Europe and south-west Asia in particular, learning about traditional farming and food production processes, and applying this knowledge to better understand archaeobotanical assemblages and transitions to agriculture. In recent years, he focused on plant foraging in prehistoric Britain, often processing and tasting plants himself to see if they were edible (he appeared to have a strong stomach), again contributing much to our understanding about plant gathering and food production. His wide-ranging experiences, expertise and knowledge meant that a conversation with Gordon often helped people to think differently and learn more deeply about our ancestors and their interactions with plants.

See here for an obituary by fellow archaeobtanist Prof. Martin Jones.

See here for an obituary by Prof. Dorian Fuller -- who became lecturer in archaeobotany at University College London when Gordon retired -- and messages from the archaeobotany community around the world. You will see from the messages that Gordon had a positive impact on many of us. We were lucky to have had Gordon in our lives.

Climate change in the past: presenting research in Paris

I participated in a fascinating conference in Paris earlier this month. The International Union of Prehistoric and Protohistoric Sciences (Union Internationale des Sciences Préhistoriques et Protohistoriques – UISPP) was founded in Bern in 1931. This organisation focuses on scientific studies of prehistoric and protohistoric materials, including archaeology, anthropology, palaeontology, geology, zoology, archaeobotany, zooarchaeology, environmental sciences, physics, chemistry, geography, history, numismatics, epigraphy and mathematics. The 18th UISPP world congress took place in Paris from 3rd to 9th June 2018. It was an enormous conference, held at the Université Paris 1 Panthéon-Sorbonne, with parallel sessions on many different aspects of archaeological science, incorporating both practice and theory.

I presented research in a session entitled "Climatic variability and societal responses during the Metal Ages in Europe and the Mediterranean (3000-300 BC)". The co-authored paper was entitled "Agricultural strategies and climate change in later prehistoric northern Europe", and it detailed some of the results from an INSTAR-funded research project: “Settlement and Landscape in Later Prehistoric Ireland – Seeing beyond the site”. This project has brought together an inter-disciplinary team to contextualise the archaeology of Late Bronze Age and Iron Age Ireland within its contemporary prehistoric landscape, focusing on farming strategies and broader landscape interactions. My role on the project is to explore archaeobotanical and zooarchaeological data.

Our "Seeing beyond the site" paper in Paris revealed results from collation and analysis of archaeobotanical and zooarchaeological data, focusing on south-east Ireland during the Late Bronze Age and Iron Age. We explored farming practices in the context of changing climates and environments, and within the broader context of northern Europe. Now we intend to write up the results for publication in a major journal -- one of my many tasks for this summer!
