In this hall (or atrium, to speak classically) the clients and visitors of inferior rank were usually received. In the houses of the more 'respectable', an atriensis, or slave peculiarly devoted to the service of the hall, was invariably retained, and his rank among his fellow-slaves was high and important. The reservoir in the centre must have been rather a dangerous ornament, but the centre of the hall was like the grass-plot of a college, and interdicted to the passers to and fro, who found ample space in the margin. Right opposite the entrance, at the other end of the hall, was an apartment (tablinum), in which the pavement was usually adorned with rich mosaics, and the walls covered with elaborate paintings. Here were usually kept the records of the family, or those of any public office that had been filled by the owner: on one side of this saloon, if we may so call it, was often a dining-room, or triclinium; on the other side, perhaps, what we should now term a cabinet of gems, containing whatever curiosities were deemed most rare and costly; and invariably a small passage for the slaves to cross to the further parts of the house, without passing the apartments thus mentioned. These rooms all opened on a square or oblong colonnade, technically termed peristyle. If the house was small, its boundary ceased with this colonnade; and in that case its centre, however diminutive, was ordinarily appropriated to the purpose of a garden, and adorned with vases of flowers, placed upon pedestals: while, under the colonnade, to the right and left, were doors admitting to bedrooms, to a second triclinium, or eating-room (for the ancients generally appropriated two rooms at least to that purpose, one for summer, and one for winter--or, perhaps, one for ordinary, the other for festive, occasions); and if the owner affected letters, a cabinet, dignified by the name of library--for a very small room was sufficient to contain the few rolls of papyrus which the ancients deemed a notable collection of books. At the end of the peristyle was generally the kitchen. Supposing the house was large, it did not end with the peristyle, and the centre thereof was not in that case a garden, but might be, perhaps, adorned with a fountain, or basin for fish; and at its end, exactly opposite to the tablinum, was generally another eating-room, on either side of which were bedrooms, and, perhaps, a picture-saloon, or pinacotheca. These apartments communicated again with a square or oblong space, usually adorned on three sides with a colonnade like the peristyle, and very much resembling the peristyle, only usually longer. This was the proper viridarium, or garden, being commonly adorned with a fountain, or statues, and a profusion of gay flowers: at its extreme end was the gardener's house; on either side, beneath the colonnade, were sometimes, if the size of the family required it, additional rooms.
