 <unk> of metalwork have been found throughout <unk> . The earlier <unk> appear to have had a considerable amount of silver available , probably from raiding further south , or the payment of subsidies to keep them from doing so . The very large hoard of late Roman <unk> found at <unk> Law may have originated in either way . The largest hoard of early Pictish metalwork was found in 1819 at <unk> 's Law in Fife , but unfortunately much was dispersed and melted down . Over ten heavy silver chains , some over 0 @.@ 5 metres ( 1 @.@ 6 ft ) long , have been found from this period ; the double @-@ linked <unk> Chain is one of only two that have a penannular ring , with symbol decoration including enamel , which shows how these were probably used as " <unk> " <unk> . The St Ninian 's Isle Treasure of 28 silver and silver @-@ gilt objects , contains perhaps the best collection of late Pictish forms , from the Christian period , when Pictish metalwork style , as with stone @-@ carving , gradually merged with Insular , Anglo @-@ Saxon and Viking styles .
