This persecution gave rise to an incident which illustrates the friendly intercourse between Christian and Saracen. In 858, Hilduin, Abbot of S. Germain-des-Prés, under the auspices of Charles le Chauve, sent two monks to Spain to procure the relics of St. Vincent. On reaching Languedoc they learned that his body had been carried to Benevento, but they also heard of the persecution at Córdova and were delighted, knowing that there must be plenty of relics to be obtained. They therefore kept on to Barcelona, where Sunifred, the next in command to the count, commended them to Abdulivar, Prince of Saragossa, with whom he had intimate relations. From Saragossa they reached Córdova, where the Mozárabic Bishop Saul received them kindly and assisted them in obtaining the bodies of St. George and St. Aurelius, except that, as the head of the latter was lacking, that of St. Natalia was substituted. With these precious spoils they returned in safety to Paris, by way of Toledo, Alcalá, Saragossa and Barcelona, to the immense gratification, we are told, of King Charles.[134] The persecution was but temporary and, a century later, in 956, we hear of Abderrhaman III sending Recemund, Bishop of Elvira (Granada), as his ambassador to Otho the Great at Frankfort, where he persuaded Liutprand of Cremona to write one of his historical works.[135] When the Cid conquered Valencia, in 1096, one of the conditions of surrender was that the garrison should be composed of Mozárabes, and the capitulation was signed by the principal Christian as well as Moslem citizens.[136]
