Huws considers that the text indicates that the manuscript was written in south Wales in the second half of the 14th century, and that the drawings point towards it being written in a religious setting. Later
marginalia suggest, says Huws, that the manuscript thereafter remained in south Wales. The Welsh antiquarian
Edward Lhuyd (1660–1709) obtained a copy of the text in 1698, copied for him by his assistant William Jones when working in
Dolgellau in north-west Wales, although the home of the manuscript is not recorded. The Welsh clergyman
William Conybeare gave it to the Neath Philosophical Society in 1835. It was referred to as "Manuscript Y" by
Aneurin Owen in his 1841 work
Ancient Laws and Institutes of Wales, a record of surviving Welsh law manuscripts, but from about 1860 onwards it was held in unknown private hands. In 1969, it was acquired by the
National Library of Wales, Aberystwyth, and added to the
General Manuscript Collection with the reference NLW MS 20143A. == References ==
