For some years, Mungo fixed his Episcopal seat at Hoddom in Dumfriesshire, evangelising thence the district of Galloway. He eventually returned to Glasgow where a large community grew up around him. It was nearby, in Kilmacolm, that he was visited by Saint Columba, who was at that time labouring in Strathtay. The two saints embraced, held long converse, and exchanged their pastoral staves. In old age, Mungo became very feeble and his chin had to be set in place with a bandage. He is said to have died in his bath, on Sunday 13 January.
