Peredur son of Efrawc
A Gwyddbwyll board appears whose pieces play by themselves. When Peredur’s favoured side loses, the opposing pieces cry out; he throws the board into a lake.
The absence
A game we cannot recover
The word Gwyddbwyll has often been rendered as “chess”, but that identification is not straightforward: the word and its literary traditions appear to be older than the arrival of chess in Europe. Its exact etymology and implications remain uncertain.
That uncertainty is not a defect to be concealed. It is part of what makes Gwyddbwyll compelling: a game known by name and by story, but not by a surviving set of rules.
In story
A game that acts
The literary appearances are not evidence for a recoverable historical ruleset. They are stories, and they make Gwyddbwyll stranger than a simple label such as “Celtic chess”.
The Thirteen Treasures of Britain
One tradition describes the Gwyddbwyll of Gwenddoleu ap Ceidio: gold for the board, silver for the pieces, and a game that plays by itself when the pieces are set down.
The Dream of Macsen Wledig
Gwyddbwyll appears again in the dream-world around Macsen, Elen and her family, amid descriptions of a magnificent golden board and the making and playing of its pieces.
A question
What might it have been for?
Yuri Leitch has explored the possibility that interpretations of the name - such as wood-sense, tree-wisdom or forest-wisdom - might point less to a solved definition than to a question about knowledge, trees, memory and play.
In this interpretation, games in an oral culture might sit alongside stories, songs and poetry as memorable structures. It is an interpretation rather than established historical evidence, but it gives the present project a useful point of departure.
Evidence
Surviving Welsh and Irish literary traditions attest to names and stories, not a recovered ruleset.
Interpretation
Meanings attached to the name and its possible implications remain open to debate.
Speculation
Ideas about knowledge, memory and trees are possibilities explored by Yuri Leitch.
Current practice
Gwyddbwyll Grove makes and plays new games in response to the question.
The Grove now
Playing with the question
Gwyddbwyll Grove does not claim to reconstruct the lost game. Instead, the Botanical Games ask what a contemporary game of wood-sense might become. Twenty trees can lead to twenty different forms of play.
The games need not combine into one definitive historical reconstruction. Together, they form a Grove: an evolving collection of physical experiments, browser-playable games and ways of thinking through play.
