The term "tablinum" refers to a room in ancient Roman houses, typically located between the atrium and the peristyle. It served as a study or office space for the head of the household, where important documents and family records were kept. The tablinum was often decorated with artwork and served as a place for receiving guests. In Roman architecture, the tablinum was an essential part of the layout of a domus, reflecting the social status of the family. It was designed to be both functional and aesthetically pleasing, often featuring large openings to allow light and visibility into the main living areas.
