From the Middle Ages onwards we can see that many historians made references to chess when writing of Ireland in previous eras to their own. The Second Battle of Moytura written in 1512 has this reference to an earlier event:
This he the king said then, that the chessboards of Tara should be fetched to him Samildánach and he won all the stakes, so that then he made the Cró of Lugh.
In 1768 we see the following reflections:
Brannumh, chess, a game played upon a square board divided into sixty-four small chequers: on each side there are eight men and as many pawns, to be moved and shifted according to certain rules; an fitcheall agus an brannamh ban, (Old Parchment,) probably means the men; gon a bhranaibh déad, with his ivory men, because made of elephant's teeth. This was a favourite game with the old Irish.
