What was the term used for a master's study in a Roman household?

The term "tablinum" refers specifically to a room within a Roman house that served as a study or office for the master of the house. It was typically situated close to the entrance and was often connected to the atrium, allowing the master to manage household affairs and conduct business within the same space. The tablinum was an important area where the owner could showcase family documents and important artifacts, emphasizing the social status and wealth of the household.

In contrast, the other terms describe different parts of a Roman household or specific concepts. The "exedra" was a room used for conversation or discussion, usually featuring seating and sometimes adorned with decorative elements. "Triclinium" refers to the dining room in a Roman house, characterized by its three couches arranged around a table, specifically for reclining during meals. "Oratorium" denotes a prayer room, a space designated for religious activities. Each of these serves distinct purposes that do not encapsulate the idea of a master’s dedicated study like the tablinum does.
