In the 8th and 9th centuries, after Christianization, the Pictish elite adopted a particular form of the Celtic brooch from Ireland, preferring true penannular brooches with lobed terminals. Some older Irish pseudo-penannular brooches were adapted to the Pictish style, for example the Breadalbane Brooch (British Museum). The St Ninian's Isle Treasure contains the best collection of Pictish forms. Other characteristics of Pictish metalwork are dotted backgrounds or designs and animal forms influenced by Insular art. The 8th century Monymusk Reliquary has elements of Pictish and Irish style.
