In 1324 the Bishop of Ossory, Richard de Ledrede, paid a lenten visit to the priory. Following an inquisition into a Kilkenny sect of heretics, Alice Kyteler and William Outlawe were ordered to appear before the Bishop to answer charges of witchcraft. Outlaw was supported by Arnold de Paor, Lord of Kells who arrested the Bishop and had him imprisoned in Kilkenny Castle for 17 days. This caused great scandal and on his release, the Bishop successfully prosecuted the heretics. Alice Kyteler fled to England and remained there, Alice Smith also fled, but her maidservant Petronilla de Meath became Ireland's first heretic to be burned at the stake.
