surviving as a church, is a unique survival in Europe. The Codex Vigilanus, completed in 976 in the region of Rioja, shows a complex mixture of several styles. Muslim and Mozarab Spain The extraordinary palace-city of Medina Azahara near Córdoba was built in the 10th century for the Ummayad Caliphs of Córdoba, intended as the capital of Islamic Andaluz, and is still being excavated. A considerable amount of the highly sophisticated decoration of the main buildings has survived, showing the enormous wealth of this very centralized state. The palace at Aljafería is later, from after Islamic Spain split into a number of kingdoms. Famous examples of Islamic architecture and its decoration are the Cathedral–Mosque of Córdoba, whose Islamic elements were added in stages between 784 and 987, and the Alhambra and Generalife palaces in Granada from the final periods of Muslim Spain. The Pisa Griffin is the largest known Islamic sculpture of an animal, and the most spectacular of a group of such figures from Al-Andalus, many made to hold up the basins of fountains (as at the Alhambra), or in smaller cases as perfume-burners and the like. The Christian population of Muslim Spain (the Mozarabs) developed a style of Mozarabic art whose best known survivals are a series of illuminated manuscripts, several of the commentaries on the Book of Revelation by the Asturian Saint Beatus of Liébana (c. 730 – c. 800), which gave subject matter that allowed the brightly coloured primitivist style full scope to demonstrate its qualities in manuscripts of the 10th century like the Morgan Beatus, probably the earliest, the Gerona Beatus (illuminated by a female artist Ende), Escorial Beatus and the Saint-Sever Beatus, which was actually produced some distance from Muslim rule in France. Mozarabic elements, including a background of brightly coloured strips, can be seen in some later Romanesque frescos. Hispano-Moresque ware pottery began in the south, presumably mainly for local markets, but Muslim potters were later encouraged to migrate to the Valencia region, where the Christian lords marketed their luxury lustrewares to elites all over Christian Europe in the 14th and 15th centuries, including the Popes and the English court. Spanish Islamic ivory carving and textiles were also very fine; the continuing industries producing tiles and carpets in the peninsula owe their origins largely to the Islamic kingdoms. After the expulsion of the Islamic rulers during the Reconquista, considerable Muslim populations, and Christian
