St. Columba, Virgin and Martyr
THIS saint was a holy nun in the monastery of Tabanos, who was beheaded for her faith by the Moors, under their King Mahomad, in Spain, in 853. Her body was thrown into the river Guadalquiver, but recovered by the Christians. Her relics are venerated, part in the priory of St. Columba, part in the royal abbey of our Lady at Niagara, but both in Old Castile. See St. Eulogius, Memor. l. 3, c. 10, and Suysken, the Bollandist, t. 5, p. 622.
