Petronilla de Meath, also called de Midia, was burned at Kilkenny on 3 November 1324. Wikipedia describes hers as the first known death by burning for heresy in Ireland or the British Isles. The Irish Times calls her the first person burned for heresy, and explains that witchcraft was yet to become a statutory crime. It says she confessed, was flogged across six parishes, and then went to the stake.

She was tried with Alice Kyteler. The Irish Times says Kyteler outlived four husbands and gathered a vast fortune. Wikipedia says Kyteler escaped with her life by fleeing, after which Petronilla was flogged and eventually burned.

According to the Irish Times, Ledrede wrote a trial account that set out the charges. Wikipedia lists them: that the accused denied Christ and the church, dismembered live animals, leaving the pieces at crossroads as offerings to a demon, stole the church keys and met there at night, and brewed potions from the organs of cocks, worms and other ingredients inside a robber's skull. The Irish Times adds that Ledrede's account has Petronilla claiming both women could fly.
