The exterior has been much modernised, and perhaps was never specially striking. It is curious only at the N.E. angle, where the wall is inlaid with coloured tiles of the fourteenth century; of all shapes, sizes, patterns and colours. The whole has a rich Moorish effect almost dazzling when the sun shines upon them. Above this rises an octagonal tower decorated with Corinthian pillars.

From all this glare and sound, hurry and bustle of life, you pass into the interior and at once are charmed, mesmerised. Calmness and repose fall upon the spirit; in a moment you have suddenly been removed from the world. At once it takes its place in the mind as ranking next to Barcelona. If some of its details are not to be too closely examined, the general effect is magnificent in the extreme.

In form it is peculiar and unlike any other cathedral, for it is almost a perfect square, but this is not observed at the first moment; the Coro occupies the centre, and a multitude of splendid columns support and separate the double aisles. The nave and aisles are all roofed to the same level, giving a very lofty appearance to the whole interior. The vaulting springs from the capitals of the main columns with an effect of beauty and grace seldom equalled. To look upwards is like gazing at a palm-forest with spreading fronds.

Like many of the Spanish churches, the light is cunningly arranged, and the shadow-effect is very telling. A solemn obscurity for ever reigns, excepting when sunbeams fall upon the windows. Towards evening the gloom deepens, and all looks weird and mysterious. The outlines of the lofty roof and spreading capitals are almost lost. We seem to be in a vast building of measureless dimensions: a dream-structure. The grey, subdued colour of the stone is perfect. Immense buttresses support the side walls, and between these are the chapels.

The first chapel on the left on entering is used as a parish church. Its Moorish ceiling is magnificent, though difficult to make out in the dim religious light that too often reigns. The chapel also contains a very remarkable alabaster tomb of Bernardo de Aragon, brother of King Alfonso. When we entered, it was almost at the end of a service, and for congregation the old priest had no one but the verger. He seemed relieved when it was over, waddled down the steps and disrobed. Then in a very kindly way he turned to us, bowed as gracefully as his rotund personage permitted, and bade us note the beauty of ceiling and tomb.

"Light a few more candles," he said to the verger, "and let us try to get at a few of the exquisitely carved details. It is considered one of the finest Moorish ceilings in Spain," he continued; "and in my opinion it is so. You will mark the depth of the sections, beauty of the workmanship, rich and gorgeous effect of the whole composition. There never was a people like those wonderful Moors—never will be again as long as the world lasts. How these candles add a charm to the scanty daylight, giving out almost a supernatural effect! Has it ever struck you in the same way, this strange mingling of natural and artificial light? It is especially refining. Then look at this tomb, and admire its beauty—though it is of a very different character from the ceiling. Here we have nothing Moorish. That overwhelming wealth and gorgeousness of imagination is absent from the cold marble. But how pure and perfect! Note that exquisite statuette of Benedict XIII.: the figures of the knights that surround him with their military orders; the drooping figures of the mourners in the niches. But after all, what is all this compared with the splendours of the cathedral itself," cried the old priest, without pausing to take breath. "Put out the lights, Mateo," turning to the verger; and then without further ceremony led the way into the larger building.

He had a large, red, amiable face, this old priest; some day we felt sure that he would die of apoplexy; but he was evidently a lover of the beautiful, and as evidently one who loved his fellow-men.

"Look!" he said, throwing up his hands as we stood entranced at the scene. "What can be more perfect? Whichever way you gaze you are met by a forest of pillars—a true forest, full of life and breath, for are not those growing like spreading palms? And where will you find pillars so lofty and massive? Where will you discover such a feeling of devotion, so mysterious a chiaroscuro? Apart from their beauty, we must not disdain these influences. They are aids to devotion, and poor, frail, erring human nature needs all the help it can receive both from without and within, from below and Above. I always tell our organist to play soft voluntaries and pull out his sweetest stops, so that he may make music which will creep into the spirit and rouse all its capacities for worship. That should be the true aim of all harmony. Look at the richness of the coro—the splendour of the carving. It all forms an effect which makes this the most wonderful and perfect cathedral in the whole of Spain."
