The most important example of this style is the Giralda, now adjacent to the magnificent Christian cathedral which was reared in later days on the foundations of the great mosque. Señor de Madrazo has reconstructed for us the general form and aspect of the finest monument of Almohade piety. The mosque replaced that which had been destroyed by the Normans, and appears to have embodied some part of the original structure, to judge from the horseshoe arches still to be seen in the Claustro de la Granada. The work was begun by order of Yusuf, the son of Abd-er-Rahman, the founder of the dynasty. The mosque formed a rectangle, extending from north to south, and surrounded by cloisters and courtyards. The interior was divided into longitudinal naves by a series of marble columns, which supported an adorned ceiling of carved and painted wood. The _mihrab_, or sanctuary, would have been at the southern extremity, after the Syrian custom, it taking the Spanish Muslims some time to realise that Mecca lay east rather than south of Andalusia. The mosque would also have contained a _maksurrah_, or vestibule, for the imam and his officials, the _nimbar_, or pulpit, for the sovereign, and the tribune for the preacher. In the northern court was the existing fountain for ablutions, surmounted by a cupola, and surrounded by orange and palm-trees. The eastern court was known as the Court of the Elms. In all probability, attached to the sacred edifice, was the _turbeh_, or tomb of the founder. The Giralda is not only the most important and famous of minarets, but is among the three or four most remarkable towers in the world. It is more to Seville than Giotto’s campanile to Florence; it rivals in fame the now vanished campanile of St Mark’s. Unlike similar edifices in Egypt and Syria, minarets among the western Moslems were built strong and massive, rather than slender and elegant. The Giralda,” says Herr Schmidt, “is one of the strongest buildings in the world, and few of our Christian church towers could have withstood so successfully the lightning and the earthquake.”
