 Thomas Charles @-@ Edwards has suggested that the kingdom of Dál Riata was a cross @-@ roads between the artistic styles of the <unk> and those of Ireland , with which the Scots settlers in what is now <unk> kept close contacts . This can be seen in representations found in excavations of the fortress of <unk> , which combine Pictish and Irish elements . This included extensive evidence for the production of high status jewellery and moulds from the seventh century that indicate the production of pieces similar to the <unk> brooch , found in Ayrshire , which may have been made in Dál Riata , but with elements that suggest Irish origins . These and other finds , including a trumpet spiral decorated hanging bowl disc and a stamped animal decoration ( or <unk> ) , perhaps from a bucket or drinking horn , indicate the ways in which Dál Riata was one of the locations where the Insular style was developed . In the eighth and ninth centuries the Pictish elite adopted true penannular brooches with lobed terminals from Ireland . Some older Irish pseudo @-@ penannular brooches were adapted to the Pictish style , for example the <unk> <unk> ( British Museum ) . The eighth century <unk> <unk> has elements of Pictish and Irish style .
