[In French Lunaire] He was of a noble family in Wales, and educated under the care of Saint Iltut; and passing over into that part of France called the province of Domnone, he founded a monastery between the rivers of Rancé and Arguenon, on a piece of ground which was given him by Jona, the lord of the country. His many extraordinary virtues drew the attention of king Childebert, who very pressingly invited him to Paris, where he was received by this prince and his royal consort Ultrogotha with every possible demonstration of the highest respect. At his return he had the affliction to hear that his protector Jona was stripped of his possessions, and murdered by Conomor. Happily however he arrived time enough to shelter that unfortunate nobleman’s son Judual from the bloody tyrant’s cruelty, and conveyed him safely to England: whence Judual afterwards returned, and recovered his inheritance. This saint is styled bishop, though he had no fixed see; for it was then an established custom in Brittany to honour the principal abbots with the episcopal dignity. The year in which Saint Leonorus died is not known. His body was translated to a parochial church near Saint Malo, which still retains the name of Saint Lunaire: here his tomb is shown, which is empty, his relics being inclosed in a shrine. The feast of his translation is on the 13th of October, but he is principally honoured in the several diocesses of Brittany on the 1st of July. He is patron of many churches.
