The Crescent was waning. All Al Mansûr’s conquests had been recovered by the Christians. Toledo fell before the arms of Alfonso III. The Castilians overran Portugal and penetrated into Andalusia. The Amir of Ishbiliyah took the only course open to him at the moment, and cultivated the friendship of the Castilian king. He consented to the removal of the body of St Isidore from Italica to Leon, and gave his daughter Zayda in a sort of left-handed marriage to Alfonso III. As the Christian king was already the husband of Queen Constancia, and Zayda’s dowry consisted of the most valuable conquests of the Amir Mut’adid, this transaction did not reflect much credit on either party. But it purchased for Seville a period of peace and security, during which its inhabitants became hopelessly enervated by luxury and ease. The Abbadite sovereigns have left but few traces on the city which they did so much to embellish and improve. To them, however, may be ascribed the foundation of the Alcazar. Such at least is the opinion of Señor de Madrazo. In the horseshoe arches of the Salón de los Embajadores with their rich Corinthian capitals--on which the names of different Khalifas are inscribed--we detect a resemblance to the mosque of Cordova, and recognise the early Saracenic style, unaffected by African, or properly Moorish, influence. To the same period and school of architecture, Señor de Madrazo attributes the ornate arcading of the narrow staircase leading from the entrance court to near the balcony of the chapel; and the three arches with capitals in the abandoned apartment adjoining the Salón de los Principes. The ultra-semicircular curve of the arch occurs very rarely in later or true Moorish architecture. The Moslem conquerors had, in the majority of cases, converted to their use the Christian churches in the cities they occupied. Many of the mosques that adorned Ishbiliyah during the reign of the race of Abbad had been adapted in this way, the lines of pillars being readjusted in most cases to give the structure that south-easterly direction that the law of Islam required. Traces of these Abbadite mosques remain in the churches of San Juan Bautista and San Salvador. On the wall of the former was found an inscription which has been thus translated by Don Pascual de Gayangos: “In the name of the clement and merciful Allah. May the blessing of Allah be on Mohammed, the seal of the Prophets. The Princess and august mother of Er-Rashid Abu-l-hosaya Obayd’ allah, son of Mut’amid Abu-l-Kasim Mohammed Ben Abbad (may Allah make his empire and power lasting, as well as the glory of both!), ordered this minaret to be raised in her mosque (which may Allah preserve!), awaiting the abundance of His rewards; and the work was finished, with the help of Allah, by the hand of the Wizir and Katib, the Amir Abu-l-Kasim Ben Battah (may Allah be propitious to me!), in the moon of Shaaban, in the year 478.”
