THIS plate introduces us to the most striking feature of all important Spanish houses, the Patio, or internal courtyard, answering to and perpetuating the Atrium of Roman architecture, with its impluvium and compluvium, and corresponding with the ordinary Cortile of the Italians. It is usually rectangular in plan, and entirely surrounded upon at least two stories by arcading, behind which run passages into which open the doors of every principal set of apartments of the house. There are rarely many windows in the walls of the Patios, as the rooms generally occupy the whole width intervening between the Patio walls, and the external walls of the house from which the light is mainly derived. There are, however, usually more windows on the lower story of the Patio than on the upper, since the chief saloons requiring most light were on the first floor, while much of the lower floor was occupied as was also usual in Italy, by retainers, servants, poor guests, mendicant friars and administradores--to say nothing of mules, and horses with stores and munitions of all sorts. Nothing can be more picturesque or better suited to the climate than these Patios, since owing to the deep arcades which surround the open part (the Cavædium) of the court-yard upon more stories than one, there is always some portion of the arcade in which shelter can be obtained from sun, rain, or wind, and in which the occupants of the several apartments can sit and work, or lounge and smoke, in abundant but not unbearable light, and perfect comfort. This facility of outlet enables them, during the hours when the sun shines most fiercely, to keep their living and sleeping rooms dark and cool, and in exactly the state to make the midday meal and subsequent siesta truly luxurious and refreshing. One open staircase usually connects the upper and lower arcades; admission is rarely given to the whole building at more than one point, the great door, adjoining which is almost always to be found the concierge, the janitor of the old Roman house, upon the model of which the Spaniards probably founded their notion of a residence at once noble and comfortable. Little need be said concerning the particular house sketched. It is one of the few left in Burgos to bear witness to the grandeur of its old aristocracy. Though once the residence of the powerful Condes de Miranda of the family of the Zunigas, it is now but a half ruined and entirely dirty lodging-house for the lower classes in a poor and neglected part of the city. A fine dedication to the most illustrious "Señor Don Francisco de çuñiga y Avellaneda, Conde de Miranda, Señor de la Villa Daça, y de la Casa de Avellaneda, by Pedro Martinez the Printer of Seville, in 1565," sets forth the arms as well as the style and title of the nobleman by whom, or by whose next descendant the "Casa de Miranda" of Burgos was probably built.
