March 11, 859
Cathedral of Oviedo
Spanish martyr and writer who flourished during the reigns of the Cordovan Caliphs, Abd-er-Rahman II and Mohammed I (822-886). It is not certain on what date or in what year of the ninth century he was born; it must have been previous to 819, because in 848 he was a priest highly esteemed among the Christians of Catalonia and Navarre, and priesthood was then conferred only on men thirty years of age. The family of the saint was of the nobility and held land in Cordova from Roman times. The Mussulman rulers of Spain, at the beginning of the eighth century, tolerated the creed of the Christians and left them, with some restrictions, their civil rule, ecclesiastical hierarchy, monasteries, and property, but made them feel the burden of subjection in the shape of pecuniary exactions and military service. In the large cities like Toledo and Cordova, the civil rule of the Christians did not differ from that of the Visigothic epoch. The government was exercised by the comes (count), president of the council of senators, among whom we meet a similarly named ancestor of Eulogius. The saint, like his five brothers, received an excellent education in accord with his good birth and under the guardianship of his mother Isabel. The youngest of the brothers, Joseph, held a high office in the palace of Abd-er-Rahman II; two other brothers, Alvarus and Isidore, were merchants and traded on a large scale as far as Central Europe. Of his sisters, Niola and Anulona, the first remained with her mother; the second was educated from infancy in a monastery where she later became a nun.
