Jenny Day has been part of the editorial team of Geiriadur Prifysgol Cymru: A Dictionary of the Welsh Language since 2013 and in 2014 joined the Cult of the Saints in Wales project as a research fellow. Previously she worked on a pilot project on neologisms for the dictionary, and on the Poetry of Guto’r Glyn project, also at the Centre. She began her career as a scientist but, after studying part-time for a BA in Welsh at Aberystwyth University, she went on to complete a PhD there in 2010, on ‘Weapons in the Hengerdd and the Works of the Poets of the Princes’. Since then she has extended her research into weapons and warfare, as perceived by the poets, and is also interested in the wider aspects of material culture and daily life in medieval Wales. Since joining the Cult of the Saints project, she has been enjoying the new experience of working with prose texts, and investigating the ways in which two important saints, David and Martin, were viewed in late medieval Wales.
