In the earliest Morisco-Spanish edifices there was not much original work. The Visigothic temples were reconsecrated to the new faith and adapted to the plans of the primitive Mohammedan mosques, but the designs and style of decoration were not purely Morisco. The work was probably influenced by Persian and ancient Egyptian art, and according to Señor F. M. Tubino it contained Semitic elements. We shall also note the incorporation of the Corinthian capital with the slender Moorish column of marbles of various colours. The characteristic horseshoe arch, with its delicate columns, was one of the earliest manifestations of the developing art of the Moors. There has been much discussion concerning the introduction of the pointed arch, which is so often claimed as ‘Gothic.’ The arch in architecture was no doubt copied from the curved interlacing of the branches of trees, and the wide, flat arch was succeeded by models of a more pointed type. In the thirteenth century the pointed arch was a comparatively common form, and it is fairly evident that its origin was in the East. In the Mosque of Jerusalem, and of Amrou, in Cairo, there were early examples of the pointed arch. The contrary flexure is a form of pointed arch, and it was used by the Moors. Sir Christopher Wren, and other authorities upon architectural art, lean to the opinion that the so-called Gothic arch is of Oriental origin. There are, however, a number of students who have endeavoured to disprove the Moorish genesis of the narrow arch. In the First Period of Morisco architecture, the talent and the energy of the designers were chiefly applied to the planning of military defences, towers, walls, and embattlements. The Second Period was one of greater security from the alarms of wars, and the architects devoted their art to devising religious structures and noble mosques. In the Third Period we see the upraising of fine secular buildings, palaces, dwelling-houses, with their courts and colonnades, and the erection of sumptuous marble baths. From the eighth to the eleventh century the style in Spain is known as the Arab-Spanish, and is sometimes called the Estilo Califato. This style is ‘Saracenic,’ with Jewish features. In the next period, from the twelfth to the thirteenth century, we have the Almohade development of Arabian architecture, whose examples may be seen in most of the Moorish cities of Spain. The last period--from the fourteenth to the fifteenth century--which marks the decline of the pure Morisco designs, is sometimes described as the Alhamares.
