Toledo. Every successive æra of civilization, with the concomitant religion on which it has been founded, and from which it has taken its peculiar mould, has, after maintaining its ground with more or less lustre, and throughout a greater or smaller duration, arrived at its inevitable period of decline and overthrow. In ceasing, however, to live, and to fill society far and wide with its enlightening influence,--in exchanging its erect attitude for the prostrate one consequent on its fall,--seldom has a creed, which has long held possession of the most enlightened intellects of our race for the time being, undergone an entire extinction, so as to disappear altogether from the face of the earth, and leave no trace of its existence. The influence of the soil, formation, and climate of the region, in the bosom of which such civilization has had its birth, on the dispositions and faculties of the race which has become its depositary, has always set its peculiar mark on its monuments, whether civil, military, or religious, but especially the last; which monuments, surviving the reign of the power to which they owe their existence, prolong and sanctify its memory, while they stand, erect and silent, over its grave; and furnish valuable information and benefit to those future generations sufficiently enlightened to consult them. If this theory of successions and vicissitudes be consonant (which probably no one will deny) with the march of events on the surface of this our planet, then do the circumstances of the present situation invest, as far as regards Spain, those relics of human genius and human enthusiasm, the venerable temples of her declining faith, with an interest beyond that which they have possessed at any period since their foundation. It is impossible to have paid any attention to the events of the last few years, without having received the conviction that the reign of Christianity is here fast approaching,--not the commencement, but the termination of its decline. Spaniards will never do things by halves; and will probably prefer the entire overthrow of ancient customs to the system pursued in France, of propping up, by government enactments and salaries, a tottering edifice of external forms, long since divested of its foundation of public belief.
