It is a no less curious _travers_ of human nature, from its being an almost universal one--that of which the modern Spaniards afford an example. They apply the term "barbarians" to the descendants of their Moorish compatriots, although they themselves have scarcely advanced a step in civilization since the day that, in the public place of Granada, Ferdinand the Catholic burned one million five thousand Arab books, being all he could collect throughout Spain; showing what tremendous power may be wielded by a single human hand, when applied to the task of undoing. That King, by a single signature, accomplished an act which may be considered as equivalent to retarding, by several centuries, the civilization of a great country,--perhaps, even, to cutting it off from the only opportunity it was destined to possess, during the present ages, of arriving at the summit which the more privileged nations are permitted to attain; while it influenced injuriously the progress of letters, science, and art throughout Europe. But we will no longer allow digressions to delay our visit to the Alcazar, where we shall find visible proof of Arab superiority, at least, in architectural science and invention. Passing to the east of the cathedral through the large open space, on the left of which is the Archbishop's palace, and on the right the cathedral and exchange, the embattled outer walls of the Alcazar stop the view in front; varied here and there with square towers, and containing in the centre an arched entrance. The present buildings occupy the south-eastern corner of the ancient enclosure of the royal residence, which comprised all the remaining space as far as the banks of the river, passing round the south side of the cathedral, and, in fact, including it in its precincts--an enclosure of about a mile and a half in circumference. An old tower, or scrap of wall, indicates here and there the position of the ancient buildings, the site of which is now occupied by two or three _plazuelas_, or squares, and several streets communicating between them. The present palace scarcely covers a third of the original extent. [Illustration: FAÇADE OF THE ALCAZAR, SEVILLE.]
