THERE is probably no city in all Spain, and few perhaps in any part of the world, in which within a similar compass, so many good, although fragmentary, materials could be found for illustrating styles and inflections of style in building, from the days of the Romans through those of the Moors and Christians, up to the period of the Renaissance, than Segovia. Of this last named period, two of the greatest masters, Gil de Ontañon and his son Rodrigo, have nobly left their mark in the splendid Cathedral, a worthy rival to that of Salamanca, also executed from the designs, and under the personal superintendence of the elder of the two Ontañones. The city, probably, owes these varied monuments to its merits, as a strong, as well as a beautiful position. Under these circumstances, it is not to be wondered at that its old walls should offer many features of interest as well as picturesqueness. In fact, to the educated eye, the former is almost a necessary ingredient to making up the latter. As I wended my way upwards, therefore, from the railway station to the town, through this gateway, about which I caught indications here of one style, and there of another, Roman, Moor, and Christian doing here a jot and there a little, that I should linger on my way for awhile; partly, perhaps, to cool myself, and partly to make the little sketch I present herewith to my readers. I need, perhaps, only add that the rough but effective cornice of the gateway is made up from its top to its bottom by different combinations of common tiles, and that its little enriched frieze is a specimen of the clever stucco-work, probably executed by workmen of Moorish descent in Renaissance times. The whole, even to the painting of the Virgin, is roughly executed, but is not the less graceful, perhaps, from the apparent absence of all effort. An aspect of spontaneity in works of art has its own particular charm, as has the semblance of the most careful solicitude under appropriate circumstances. The true artist, heedful of his "when" and "how," is master of both moods. [Illustration: PLATE 29 SEGOVIA MDW 1869 THE ALCAZAR.
