period (5th to 7th centuries) In 452, Saragossa fell under the power of the Suevian king Reciarius; in 466, under that of the Visigoth king Euric. St. Isidore extolled it as one of the best cities of Spain in the Gothic period, and Pacensis called it "the most ancient and most flourishing." In 542, when the Franks laid siege to Saragossa to take vengeance for the wrongs of the Catholic princess, Clotilde, the besieged went forth in procession and delivered to the enemy, as the price of their raising the siege, a portion of the blood-stained stole of St. Vincent, the deacon. From 592 to 619 the bishop was Maximus, who assisted at the Councils of Barcelona and Egara. Under his episcopate the Second Council of Zaragoza was held in 592 against Arianism. Maximus' name, combined with that of the monk Marcus, has been used to form an alleged Marcus Maximus, the apocryphal continuator of Flavius Dexter. The See of Saragossa was occupied during the Gothic period by two illustrious bishops: St. Braulius (631–651), who assisted at the Fourth, Fifth, and Sixth Councils of Toledo; and Taius (Tajón) (651–664), famous for his own writings and for having discovered at Rome the third part of St. Gregory's "Morals." The Third Council of Saragossa was held in 691 under Bishop Valderedus, and provided that queens, when widowed, should retire to some monastery for their security and for the sake of decorum. Moorish period (714–1118) During the Moorish occupation Catholic worship did not cease in this city; the churches of the Virgin and of St. Engratia were maintained, while that of the Saviour was turned into a mosque. Of the bishops of this period the names are preserved of Senior, who visited St. Eulogius at Cordoba (849), and of Eleca, who in 890 was driven from the city by the Muslims and took refuge at Oviedo. Paternus was sent by king Sancho the Great to Cluny to introduce the Cluniac reform into Spain in the monasteries of San Juan de la Peña and San Salvador de Leyre, and was afterwards appointed Bishop of Saragossa (1040–1077). Christian period (1118–1318) King Alfonso I the Battler of Aragon reconquered the city on 18 December 1118, and named as bishop Pedro de Librana, whose appointment was confirmed by Pope Gelasius II. López, in his Historia de Zaragoza, says that Pedro de Librana first resided at the Church
