which derived their name from their lofty isolation from neighbouring buildings,[24] continued to spring up, and even private houses soon came to attain a height which had to be restrained by the intervention of the law. An ex-consul and augur was called on by the censors of 125 to explain the magnitude of a villa which he had raised, and the altitude of the structure exposed him not only to the strictures of the guardians of morals but to a fine imposed by a public court.[25] Great changes were effected in the interior structure of the houses of the wealthy--changes excused by a pardonable desire for greater comfort and rendered necessary both by the growing formality of life and the large increase in the numbers of the resident household, but tending, when once adopted, to draw the father of the family into that most useless type of extravagance which takes the form of a craze for building. The Hall or Atrium had once been practically the house. It opened on the street. It contained the family bed and the kitchen fire. The smoke passed through a hole in the roof and begrimed the family portraits that looked down on the members of the household gathered round the hearth for their common meal. The Hall was the chief bedroom, the kitchen, the dining-room and the reception room, and it was also the only avenue from the street to the small courtyard at the back. The houses of the great had hitherto differed from those of the poor chiefly in dimensions and but very slightly in structure. The home of the wealthy patrician had simply been on a larger scale of primitive discomfort; and if his large parlour built of timber could accommodate a vast host of clients, the bed and the cooking pots were still visible to every visitor. The chief of the early innovations had been merely a low portico, borrowed from the Greeks by the Etruscans and transmitted by them to Rome, which ran round the courtyard, was divided into little cells and chambers, and served to accommodate the servants of the house.[26] But now fashion dictated that the doorway should not front the street but should be parted from it by a vestibule, in which the early callers gathered before they were admitted to the hall of audience. The floor of the Atrium was no longer the common passage to the regions at the back, but a special corridor lying either on one or on both sides of the Hall[27] led past the Study or Tablinum, immediately behind it, to the inner court beyond. Even the sanctity of the nuptial couch could not continue to give it the publicity which was irksome to the taste of an age which had acquired notions of the dignity of seclusion, of the comfort that was to be found in retirement, and of the convenience of separating the chambers that were used for public from those which were employed for merely private purposes. The chief bedrooms were shifted to the back, and the sides of the courtyard were no longer the exclusive abode of the dependants of the household.
