The cubiculum was a private room in an ancient Roman house occupied by a high-status family, a domus. It usually led directly from the atrium, but in later periods it was sometimes adjacent to the peristyle. It was used for the functions of a modern bedroom, sleep and sex, as well as for business meetings, the reception of important guests and the display of the most highly-prized works of art in the house. It was also a preferred venue for murder and suicide. A room used only for sleeping was not classed as a cubiculum.
