tains of Castile. Each succeeding age and race beautified and embellished it, and each, departing, left the trace of its passage in the abiding granite of its monuments. The Romans left the glorious aqueduct, that work of demigods who scorned to mention it in their histories; its mediaeval bishops bequeathed to later times their ideas of ecclesiastical architecture; and the Arabs the science of fortification and the industrial arts.
Its very ruin and decay makes it only more precious to the traveller. There are here none of the modern and commonplace evidences of life and activity that shock the artistic sense in other towns. All is old, moribund, and picturesque. It lies here in the heart of the Guadarramas, lost and forgotten by the civilization of the age, muttering in its senile dream of the glories of an older world. It has not vitality enough to attract a railroad, and so is only reached by a long and tiresome journey by diligence. Its solitude is rarely intruded upon by the impertinent curious, and the red back of Murray is a rare apparition in its winding streets.
Yet those who come are richly repaid. One does not quickly forget the impression produced by the first view of the vast aqueduct, as you drive into
THE AQUEDUCT FROM THE MARKET, SEGOVIA
A CASTLE IN THE AIR 209

It comes upon you in an instant,--the two great ranges of superimposed arches, over one hundred feet high, spanning the ravine-like suburb from the outer hills to the Alcázar. You raise your eyes from the market-place, with its dickering crowd, from the old and squalid houses clustered like shot rubbish at the foot of the chasm, to this grand and soaring wonder of utilitarian architecture, with something of a fancy that it was never made, that it has stood there since the morning of the world. It has the lightness and the strength, the absence of ornament and the essential beauty, the vastness and the perfection, of a work of nature.
It is one of those gigantic works of Trajan, so common in that magnificent age that Roman authors do not allude to it. It was built to bring the cool mountain water of the Sierra Fonfria a distance of nine miles through the hills, the gulches, and the pine forests of Valsain, and over the open plain to the thirsty city of Segovia. The aqueduct proper runs from the old tower of Caserón three thousand feet to the reservoir where the water deposits its sand and sediment, and thence begins the series of one hundred and nineteen arches, which traverse
