Some time later Mungo left Scotland for a period but he was asked back by King Rhydderch Hael whose kingdom was based in Dumbarton, farther down the River Clyde. Glasgow`s coat of arms takes its symbol of a salmon with a ring in its mouth from this period and the ring was a present from the king to his wife Languoreth who was having a relationship with a young soldier. She foolishly gave him the ring and one day the king found the soldier asleep, saw the ring, removed it from the soldier`s finger and threw it into the River Clyde. He then challenged his wife to show him the ring and when she was unable to do so she was cast into a cell. In her desperation she asked Mungo for help and he had someone catch a salmon from the river. And, yes, the ring was found inside the fish.

The square metal bell on the coat of arms may possibly have been given to Mungo by the Pope when he visited Rome but unfortunately it no longer survives. Priests` bells were important many centuries ago as people would leave an endowment to pay for the bell to be rung to call people to pray for their soul.

Mungo continued to perform miracles during his time as Glasgow`s bishop and after he died (c.612) his shrine in the Cathedral became a place of pilgrimage.
