Several works on Spanish architecture have been written (the reader will find them mentioned elsewhere), but none treats the matter from an evolutionary standpoint. On the contrary, most of them are limited to the study of a period, of a style or of a locality; hence they cannot claim to be a _dernier mot_. Such a work has still to be written. Be it understood, nevertheless, that the author does not pretend--_Dios me libre!_--to have supplied the lack in the following pages. In a couple of thousand words it would be utterly impossible to do so. No; a complete, evolutionary study of Spanish architecture would imply years of labour, of travel, and of study. For so much on the peninsula is hybrid and exotic, and yet again, so much is peculiar to Spain alone. Thus it is often most difficult to determine which art phenomena are natural--that is, which are the logical results of a well-defined art movement--and which are artificial or the casual product of elements utterly foreign to Spanish soil. Willingly the author leaves to other and wiser heads the solving of the above riddle. He hopes, nevertheless, that they (those who care to undertake the mentioned task) will find some remarks or some observations in the following chapters to help them discover the real truth concerning the Spaniard's love, or his insensibility for architectural monuments, as well as his share in the erection of cathedrals, palaces, and castles. Spanish architecture--better still, architecture in Spain--is peculiarly strange and foreign to us Northerners. We admire many edifices in Iberia, but are unable to say wherefore; we are overawed at the magnificence displayed in the interior of cathedral churches and at a loss to explain the reason. As regards the former, it can be attributed to the Oriental spirit still throbbing in the country; not in vain did the Moor inhabit Iberia for nearly eight hundred years! The powerful influence of the Church on the inhabitants, an influence that has lasted from the middle ages to the present day, explains the other phenomenon. Even to-day, in Spain, the Pope is supreme and the princes of the Church are the rulers. Does the country gain thereby? Not at all. Andalusia is in a miserable state of poverty, so are Extremadura, La Mancha, and Castile. Not a penny do the rich, or even royalty, give to better the country people's piteous lot; neither does the Church. It is nevertheless necessary to be just. In studying the evolutionary history of architecture in Spain, we must praise the tyranny of the Church which spent the millions of dollars of the poor in erecting such marvels as the cathedral of Toledo, etc., and we must ignore the sweating farmer, the terror-stricken Jew, the accused heretic, the disgraced courtier, the seafaring conquistador, who gave up their all to buy a few months' life, the respite of an hour.
