Thomas Parry and the Green Ointment
Have you ever heard any stories of the Parry, Griffiths, Wiliams or Rowlands families, herbalists from Dyffryn Ogwen?
Nearly no one knows about the ‘Llysieuaeth Feddygol’, a herbal book written in Welsh in the mid 19th Century by Thomas Parry (c1801-1858), a herbalist and quarry worker (he worked as a slate framer).
It’s a small volume of 112 pages containing 300 herbs, many of which still grow in the area he lived, by the Gors in Tregarth.



So how can we learn more about the man, his life, his community and his medicine?
THOMAS PARRY AND THE GREEN OINTMENT is a creative R&D project. We are exploring the stories of the people, plants and community of the book, through archive research and community workshops, to explore medicine making, plant spotting, research history and how to tell stories and write poems inspired by plants and history.
There are community workshops happening in Tregarth and Bethesda in July, August and September. They are totally free but you do need to register in advance.

MY BIG PROJECT LAST YEAR was Sacred Herbs of Britain, a version of the story of Culhwch and Olwen. She was the giant’s daughter with hair yellower than the blossoms of the broom and cheeks pinker than the foxglove. Interweaving myths and magic, herbal lore and folk tales, this show shares stories of the plants and trees found in Olwen’s landscape, inspired by folklore from across Wales.
