Entry 5: Al-Andalus
While reading Richard Fletcher's Moorish Spain, I was struck by the similarity of the architectural style demonstrated in the Great Mosque of Cordoba in Spain and that of the Carolingian and Ottonian churches to the north, which I studied last semester.
First, a look at the interior of the Great Mosque. Now, if one looks at a photo of Charlemagne's Palatine Chapel at Aachen, or, even more strikingly, the church at Hildesheim, a single shared feature will stand out among the three: the starkly contrasting stones of the rounded arches throughout each building. In Hildesheim and the Mosque, they are even of the same color, suggesting perhaps that the marble is of common origin, though this is to get ahead of myself somewhat.
In overall style, these buildings could hardly differ more from one another. Hildesheim harkens back to the old Roman basilica with clean lines, a flat ceiling, and a clearly demarcated three-part elevation (arcade, triforium, clerestory). The Palatine Chapel is of a circular plan and exudes a uniquely Carolingian aura of solidity and presence, granted by the immense piers and otherwise superfluous colonettes on the third tier. In perfect contrast, the thin columns of the Mosque bear a closer resemblance to the Gothic style of the late medieval period, as they create an ethereal space, easily flooded with light.
The salient ornamentation, however, is consistent between the three. At Hildesheim, the bands of color are somewhat narrower, but the effect is similar, and immediately calls to mind the Muslim and Carolingian predecessors. So, barring the possibility that both the Islamic and Christian architects just really liked the pattern and independently chose to use it in the same type of building, in the same position, and at the same time, where did the style originate?
As Barton mentions in his A History of Spain, trade between the two cultures was fairly common, and treaties between the Christians remaining in the northern regions of Iberia and Al-Andalus were not unheard of (Constable, Medieval Iberia, p37). So, one of the two may have acted as a source for not only merchant's goods, but artistic influence as well. But which one?
From what I've learned of early Christian architecture, I would suggest that the Muslim architects were responsible for this particular stylistic import, rather than the Christians bringing it to Al-Andalus. If one goes back a few centuries to the time of Constantine's conversion to Christianity, the surviving basilicas and records thereof do not seem to possess this element, nor does the familiar knot-work style of the Hiberno-Saxons of the period between the fall of Rome and the rise of The Holy Roman Empire suggest anything so stark as this pattern.
