Conference

I am a member of the team who is currently organising a conference.

Looking back, moving forward: 70 years of Environmental Archaeology in Ireland

Date: Friday 19^th February 2016

Location: National Botanic Gardens, Dublin

Organisers: Environmental Archaeology in Ireland (EAI)workgroup

Sponsor: National Monuments Service, Department of Arts, Heritage and the Gaeltacht




It is almost 70 years since the publication of Frank Mitchell’s seminal paper “Evidence of early agriculture” in the Journal of the Royal Society of Antiquaries of Ireland. In this paper, Mitchell outlined exciting new scientific approaches for investigating agriculture and environments in ancient Ireland. Since the publication of this paper, environmental archaeology in Ireland has grown and flourished. Environmental archaeologists now explore human-environment interactions through the scientific investigation of many different types of remains, including preserved plants, wood, animal bones, insects and other materials. These analyses can reveal what people ate in the past, how they organised their economies, and how people interacted with their local environments and wider landscapes.

This conference will seek to explore how environmental archaeology developed in Ireland, where we are now, and how we can move forward. What are the strengths and expertise in Irish environmental archaeology? Where are the gaps in knowledge and skills? What are the challenges in practice? Through a day of lectures and interactive discussion, this conference will seek to set out a vision for environmental archaeology in 21^st century Ireland.

Attendance will be free, but registration will be required. We will open registration in November 2015. See http://eaireland.blogspot.ie/ for further information.

Community Archaeology: bringing archaeobotany to a new audience

Swords Castle project website

One of my current roles is the provision of environmental advice to the team who is excavating Swords Castle in Co. Dublin. A fantastic new project has been established, Swords Castle: Digging History, which is a Community Archaeology project designed and supported by Fingal County Council. Under the leadership of Fingal’s community archaeologist, Christine Baker, the project helps to engage both locals and tourists with fascinating aspects of our past. As the project website notes, “A series of ‘knowledge gaps’ were identified in the Swords Castle Conservation Plan 2014.  Although it is the best surviving example of a Dublin archbishop’s palace and was an important administrative centre there are some questions that remain unanswered; Is there a graveyard underneath the castle? Were there buildings within the yard? How old are the different buildings? Through this project we hope to answer at least some of these questions.”

The 2015 excavation season took place in August and September. Members of the public were invited to play an important role in the excavation as volunteers, where they had the opportunity to experience many different aspects of archaeological excavation, including digging, organising artefacts, washing pottery and bone, and processing environmental samples. My role on the project was to introduce the concept of environmental archaeology to people who had little or no experience in archaeology. I explained how the tiny fragments of plants (often seeds) can become burnt and are thereby preserved, and they can survive in the soil for thousands of years. We discussed how a great variety of plant remains can be recovered from soil samples taken during the excavation, and these plant remains can tell us about past diets and environments. Many of the volunteers were amazed and fascinated by this ‘hidden’ aspect of the Swords Castle excavation – who would think that such tiny things could survive and reveal so much!

 

When I was at the excavation, I also showed the volunteers how to process these soil samples. We used the flotation method to separate preserved plant remains from the soil. This method involves placing the soil sample into a bucket, adding water and stirring it all gently. Any charred plant remains and other organic material such as wood charcoal usually float to the surface of the water. The water is then poured into a fine-mesh sieve to catch the organic remains, and this material is left to dry before being bagged up. Lots of samples were processed, and now I have them back in my lab, awaiting analysis. Watch this space for the results!

Celebrating Heritage Week 2015

In Ireland, we have just finished celebrating Heritage Week 2015. Heritage Week in Ireland is coordinated by the Heritage Council and is a part of European Heritage Days. These are a joint initiative of the Council of Europe and the European Union in which over forty countries participate each year. 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. Heritage is so important in Ireland that we spend a whole week celebrating European Heritage Days!

I was involved in several events that took place during Heritage Week. One of these events was organised by team members from my current major research project, "Seeing Beyond the Site: Settlement and Landscape in Later Prehistoric Ireland". The project is funded through the INSTAR scheme, which is coordinated by the Heritage Council. For Heritage Week, the team decided to show how we are using archaeological science to find out about foods, environments and people in ancient Ireland.

We held an 'open-lab' morning at the Department of Archaeology, University College Cork, where our project is based. Over the course of three separate hour-long sessions, members of the public learned about the period that we are studying (Late Bronze Age and Iron Age Ireland, 1200 BC to AD 400), the types of plant and animal foods that were eaten, how foods were processed, and what local environments would have looked like.

An update from our Twitter account

We started with an introduction from Dr Katharina Becker, who welcomed participants and explained what we are doing in our research project. Then we moved onto my area - archaeobotany. We looked at charred barley grains dating to the Late Bronze Age, and we compared them with modern barley grains to understand how the archaeological material had become preserved. We also looked at other types of cereals that were eaten in late prehistory, and then we learnt about the types of foods and drinks that would have been produced. Thanks to the National Museum of Ireland, our visitors were able to grind cereal grains on a real archaeological quern stone, possibly dating to the Bronze Age. We estimate that this was the first time in more than 3000 years that the quern stone had been used to grind grain!

We then moved on to look at animal bone with Caitlin Nagle, learning about the many animals that were farmed and hunted, and how their bone remains can provide insights into how animals were raised and butchered. Finally, Dr Ben Gearey showed how teeny-tiny pollen remains can provide remarkable insights into the types of environments in which people were living (and people's impacts on their environments), and how we can look at ancient farming strategies through pollen analysis.

The visitors to our open lab were a bright bunch, asking lots of good questions and having fun with the hands-on quern experience. We were delighted that we had a full house for each session. Public engagement is an important aspect of our project, so watch this space for further initiatives over the course of the project.
