floor. The atrium might also contain a fountain, which piped in drinking water from an aqueduct (riverwater and well water was preferred for drinking). Reliable piped water made the rain-collecting function dispensable, and Late-Empire domusses often replace atria with peristyle gardens, which could also be made larger. Ceremonial uses After a birth, a bed for Juno and a table for Hercules were set up in the atrium. The tollere liberum (ceremony for a newborn), dedication of the bulla at Liberalia (coming-of-age, male), and confarreatio marriage were described as conducted in the atrium, in front of the lararium. The wedding couch or bed, the lectus genialis, was placed in the atrium, on the side opposite the door or in one of the alae. The lectus funebris, or funeral couch, was placed in the atrium, and the body of the deceased was laid in state upon it with feet facing the door. Everyday uses The cavaedium was a communal space. Varro says it is "left open to the common use of all". Vitruvius describes it as a room which "any of the people have a perfect right to enter, even without an invitation". It was thus a sort of living-room. Spinning and weaving, major household tasks, were traditionally done in the atrium, as were other domestic occupations. Toys, flutes, writing materials, cutlery, and crockery have all been found in atria. Historically, the atrium was probably used for cooking, with the compluvium serving as a smoke-hole. This probably continued in poorer households, but richer ones developed a separate kitchen. Similarly, historically the household slept in the cubicles opening off the atrium, but as townhouses became deeper family tended to live deeper in the house, and these became guest rooms (unless the house has dedicated guest rooms, a hospitium). Slaves and servants might sleep in the entrance to their master's cubiculum. Richer Romans received visitors in the mornings, as their clientes gathered in the atrium for the salutatio. The patron often greeted them from the tablinum. The atrium was generally the most elaborate room, with the finest artworks, wall paintings, imported marble wall-linings, and marble or mosaic floors (mosaics being even more expensive than imported marble slabs). The homes of the richest Romans became more ostentatious as increasing wealth inequality increased housing inequality, and as it became less socially important to display frugalitas and abundentia, and more important to display tryphé.
