As it would have been difficult or impossible to have kept alive a lamp or torch in so dense a steam, there is near the door a circular hole, closed formerly by a glass, which served to admit the light of a lamp placed in the adjoining chamber. The hypocaust, or furnace and apparatus, 25, for heating the water, are so placed that they can not be seen from the triangular court. They are small, but correspond with the small quantity of boiling water which they were required to furnish. _f._ Stone table. _g._ Cistern. _h._ Mouth of hypocaust. _i._ A furnace, probably for boiling water when merely a tepid bath was required, without heating the suspensura caldariorum. By the side of the hypocaust were placed the vases for hot and cold water, as described in the chapter on Baths; their pedestals were observable between the mouth of the furnace and the letter _k._ _l._ Wooden staircase, no longer in existence, which led to the apartments above. 26. Reservoir. Such was the distribution of this bath. Some paintings and mosaics, which are ordinary enough, formed its only decorations; yet, from the little that remains, we can discover that the good taste which reigned everywhere, and the freshness of the colors, must have rendered the effect of the whole most agreeable. 27. This chamber seems to have been used as a wardrobe, where the numerous garments of the opulent masters of this dwelling were kept under presses, to give them a lustre. This conjecture is founded upon the remains of calcined stuffs, and the fragments of wardrobes and carbonized plank found in the course of excavation. 28. Great gallery, lighted by windows which looked upon the two terraces, 34, separated by the large hall, 33. This gallery furnished an agreeable promenade, when the weather did not permit the enjoyment of the external porticoes or terraces. 29, 29. These two small apartments, which were open to the gallery, and probably were closed by glass, may very well have been, one a library, the other a reading-room, since the place in which books were kept was not usually the place in which they were read; being small and confined, suitable to the comparatively small number of volumes which an ancient library generally contained, and also to the limited space within which a considerable number of rolls of papyrus might be placed. A bust, painted on the wall of one of them, confirms this supposition, for it is known that the ancients were fond of keeping the portraits of eminent men before their eyes, and especially of placing those of literary men in their libraries.
