The Archbishop of Canterbury, John Peckham when involved in negotiations with Llywelyn on behalf of King Edward in 1282 sent Llywelyn a letter in which he denounced Welsh law, stating that King Hywel must have been inspired by the devil. Peckham had presumably consulted the Peniarth 28 manuscript which was apparently held in the library at St. Augustine's Abbey, Canterbury at this time. One of the features to which the English church objected was the equal share of land given to illegitimate sons. Following Llywelyn's death the Statute of Rhuddlan in 1284 introduced English criminal law into Wales: "in thefts, larcenies, burnings, murders, manslaughters and manifest and notorious robberies — we will that they shall use the laws of England". Nearly two hundred years after Welsh law ceased to be used for criminal cases, the poet Dafydd ab Edmwnd (fl. 1450–80) wrote an elegy for his friend, the harpist Siôn Eos, who had accidentally killed a man in a tavern brawl in Chirk. Siôn Eos was hanged, and Dafydd ab Edmwnd laments that he could not have been tried under the more humane Law of Hywel rather than "the law of London".
