_Art and Architecture_.--Perhaps the Arabians in Spain are known more by their architecture than any other phase of their culture. Not that there was anything especially original in it, except in the combination which they made of the architecture of other nations. In the building of their great mosques, like that of Cordova and of the Alhambra, they perpetuated the magnificence and splendor of the East. Even the actual materials with which they constructed these magnificent buildings were obtained from Greece and the Orient, and placed in their positions in a new combination. The great original feature of the Mooresque architecture is found in the famous horseshoe arch, which was used so extensively in their mosques and palaces. It represented the Roman arch, slightly bent into the form of a horseshoe. Yet from architectural strength it must be considered that the real support resting on the pillar was merely the half-circle of the Roman arch, while the horseshoe was a continuation for ornamental purposes. The Arab-Moors were forbidden the use of sculpture, which they never practised, and hence the artistic features were limited to architectural and art decorations. Many of the interior decorations of the walls of these great buildings show advanced skill. Upon the whole, their buildings are remarkable mainly in the perpetuation of Oriental architecture rather than in the development of any originality except in skill of decoration and combination. _The Government of the Arab-Moors Was Peculiarly Centralized_.--The caliph was at the head as an absolute monarch. He appointed viceroys in the different provinces for their control. The only thing that limited the actual power of the caliph was the fact that he was a theocratic governor. Otherwise he was supreme in power. There was no constitutional government, and, indeed, but little precedent in law. The government depended somewhat upon the whims and caprices {316} of a single individual. It was said that in the beginning the caliph was elected by the people, but in a later period the office became hereditary. It is true the caliph, who was called the "vicar of God," or "the shadow of God," had his various ministers appointed from the wise men to carry out his will. Yet, such was the power of the people what when in Spain they were displeased with the rulings of the judges, they would pelt the officers or storm the palace, thus in a way limiting the power of these absolute rulers.
