Aoife Daly (Denmark) “Timber supply for ‘Cogs’, and other topical tree-ring tales”

Aoife has worked with dendroarchaeology in Scandinavia since 1997. Navigating between research opportunities and dendrochronology for commercial archaeology, she analyses hugely diverse timber remains from our human past. Her specific research interest is on past timber trade, by identifying the provenance of archaeological and historical timber. She has carried out non-invasive analysis of wood from the Norwegian Viking ship burials, polychrome sculpture, painted panels and ancient books. Most recently, she was PI of a cross-disciplinary ERC Starting Grant Northern Europe’s timber resource – chronology, origin and exploitation (TIMBER) grant no.: 677152. Using archaeological, historical and scientific methods, the trade of timber in Northern Europe, was examined, filling major gaps in our knowledge of past use of this sought-after resource.
