A cabinet (also known by other terms) was a private room in the houses and palaces of early modern Europe serving as a study or retreat, usually for a man. The cabinet would be furnished with books and works of art, and sited adjacent to his bedchamber, the equivalent of the Italian Renaissance studiolo. In the Late Medieval period, such newly perceived requirements for privacy had been served by the solar of the English gentry house, and a similar, less secular purpose had been served by a private oratory.
Such a room might be used as a study or office, or just a sitting room. Heating the main rooms in large palaces or mansions in the winter was difficult, and small rooms were more comfortable. They also offered more privacy from servants, other household members, and visitors. Typically such a room would be for the use of a single individual, so that a house might have at least two (his and hers) and often more. Names varied: cabinet, closet, study (from the Italian studiolo), office, and a range of more specifically female equivalents, such as a boudoir.
