He is said to have been a native of Ireland, and the inseparable companion of Saint Fursey, with whom he passed into France. After the death of that saint (who is honoured on the 16th of January) Maguil retired among the monks of Saint Riquier, whom he exceedingly edified by his virtues; but fearing that the extraordinary veneration in which he was held might expose him to the suggestions of pride, he, with the abbot’s leave, hid himself in the solitude of Monsterlet, upon the river Authie, where he served God with new fervour in all the exercises of a contemplative life. Here he was visited by a holy English recluse named Vulgan, 1 with whom he contracted a strict friendship, and they afterwards lived together for several years. The latter being seized with a mortal illness, endeavoured to comfort his companion, whose grief on the occasion was excessive; and exhorting him to have sentiments more becoming a Christian, “You should tremble,” says he, “lest by this grief you offend God, and lose all the fruit of your labours.” The abbot and monks of Saint Riquier being apprized of the situation of Vulgan, administered to him the sacraments, and after his death buried him in the chapel of the hermitage. Saint Maguil survived him but a short time, having died about the year 685. His body was buried in the same tomb with that of his holy companion, but was afterwards removed into a church of his name built near Saint Riquier. He is honoured on this day, which is supposed to be the day on which he died.
