Act, 1994, with a new Section 2 being included in the legislation. The Ardagh Chalice dates from around the same period, perhaps a century earlier, of the Derrynaflan Hoard and was found close by in neighbouring County Limerick in the late 19th century. At the time both were made, the ruling dynasty in Tipperary and most of Munster were the Eóganachta, while their longtime allies and possible cousins the Uí Fidgenti ruled in the Limerick area. Feidlimid mac Cremthanin, king-bishop of Cashel, who became King of Munster in 821 and died in 847, was a patron of the monastic foundation at Derrynaflan and has been suggested as a possible patron of the chalice. As a masterpiece of Insular art, the Derrynaflan chalice was included in the exhibition "The Work of Angels: Masterpieces of Celtic Metalwork, 6th–9th Centuries AD" (London, 1989, included in the catalogue).
