(A.D. 874.) [Aberdeen Breviary.] S. Adrian, bishop of S. Andrews, trained the holy man from his childhood, and appointed him to be his archdeacon. He afterwards sent him to preach the Gospel in the island of May, at the mouth of the Frith of Forth; he then went into Fife. The Church suffered severely from the incursions of the Northmen who ravaged the coasts, burning churches and monasteries, robbing them of their sacred vessels, and carrying off the unfortunate people captive. S. Monan is said by Butler to have been martyred by these invaders, but this is inaccurate. There is no evidence that he died any other than a peaceful death. He was buried at Inverny. [Illustration: S. RUDESIND. After Cahier. March 1.] S. LEO, ABP. OF ROUEN, M. (ABOUT A.D. 900.) [Gallican Martyrology; on this day at Bayonne. By Saussaye and Ferrarius on March 3rd. Authority:--Two lives of no great antiquity, one written shortly after 1293.] Leo, Gervase, and Philip, were the three sons of pious parents in the North of France; Leo was elected to be archbishop of Rouen, but resigned his government of the diocese into the hands of vicars, and betook himself with his two brothers to Bayonne, where Christianity had made but small progress, much heathen superstition remained, and a colony of Moors had settled there. He was well received, and succeeded in making many converts, but was killed by some pirates who had lived in the town, but had been ejected by the citizens on account of their nefarious deeds. According to the legend, a spring of water bubbled up where S. Leo fell, and he arose and carried his head to the place where he had last been preaching. He is represented in Art, at Bayonne, where he is greatly venerated, as a bishop, holding his head in his hands. S. RUDESIND, B. C. (A.D. 977.) [Spanish and Benedictine Martyrologies.
