Detached seal of Gavin Dunbar, Archbishop of Glasgow. Pendant on a tag.
The seal represents St Kentigern with nimbus, wearing episcopal vestments and a mitre. With his right hand he holds a salmon with a ring in its mouth, and with his left hand a crozier. He stands within a niche of Gothic style with a pinnacled canopy supported upon pillars and flanked by carved screens. beneath the niche is a shield bearing arms: three cushions within a double tressure flory counter-flory. The legend is between carved borders: SIGILLVM GAVINI ARCHIEPI GLASGVENSIS.
The document was written on parchment by the notary Hugo Curry and it is bearing his authentification mark. It is written in a bastard hand. The first letter is ornamented.
