At Pompeii, a second or third story was rarely of importance, being built only above a small part of the house, and containing rooms for the slaves; differing in this respect from the more magnificent edifices of Rome, which generally contained the principal eating-room (or caenaculum) on the second floor. The apartments themselves were ordinarily of small size; for in those delightful climes they received any extraordinary number of visitors in the peristyle (or portico), the hall, or the garden; and even their banquet-rooms, however elaborately adorned and carefully selected in point of aspect, were of diminutive proportions; for the intellectual ancients, being fond of society, not of crowds, rarely feasted more than nine at a time, so that large dinner-rooms were not so necessary with them as with us. But the suite of rooms seen at once from the entrance, must have had a very imposing effect: you beheld at once the hall richly paved and painted--the tablinum--the graceful peristyle, and (if the house extended farther) the opposite banquet-room and the garden, which closed the view with some gushing fount or marble statue. The reader will now have a tolerable notion of the Pompeian houses, which resembled in some respects the Grecian, but mostly the Roman fashion of domestic architecture. In almost every house there is some difference in detail from the rest, but the principal outline is the same in all. In all you find the hall, the tablinum, and the peristyle, communicating with each other; in all you find the walls richly painted; and all the evidence of a people fond of the refining elegancies of life. The purity of the taste of the Pompeians in decoration is, however, questionable: they were fond of the gaudiest colors, of fantastic designs; they often painted the lower half of their columns a bright red, leaving the rest uncolored; and where the garden was small, its wall was frequently tinted to deceive the eye as to its extent, imitating trees, birds, temples, etc., in perspective--a meretricious delusion which the graceful pedantry of Pliny himself adopted, with a complacent pride in its ingenuity. But the house of Glaucus was at once one of the smallest, and yet one of the most adorned and finished of all the private mansions of Pompeii: it would be a model at this day for the house of 'a single man in Mayfair'--the envy and despair of the coelibian purchasers of buhl and marquetry. You enter by a long and narrow vestibule, on the floor of which is the image of a dog in mosaic, with the well-known 'Cave canem'--or 'Beware the dog'. On either side is a chamber of some size; for the interior part of the house not being large enough to contain the two great divisions of private and public apartments, these two rooms were set apart for the reception of visitors who neither by rank nor familiarity were entitled to admission in the penetralia of the mansion.
