Cornish saint who gave his name to the town of this name. Baring-Gould identifies him with Magnenn of Kilmainham, an Irish roving bishop who had a pet ram, was given to cursing his enemies, and favoured bizarre austerities. He once asked counsel from Maelruain who roundly refused to administer reconciliation to a man who did not work for his daily bread but lived on alms. The prophecy was attributed to him that ‘A time shall come when girls shall be pert and tart of tongue; when there will be grumbling and discontent among the lower classes and lack of reverence to elders; when churches will be slackly attended and women shall exercise wiles.’ It must be said that this identification is far from certain; Mawnan may well be a local founder of whom nothing is known; the Cornish Church calendar lists him as a saint whose ‘day is not certainly known’. Feast: 18 (or 26) December, in Ireland.
Baring-Gould and Fisher, iii. 453–7.
