In
Roman architecture, a tablinum (or tabulinum, from tabula, board, picture) was a room generally situated on one side of the
atrium and opposite to the entrance; it opened in the rear on to the
peristyle, with either a large window or only an anteroom or curtain. The walls were richly decorated with
fresco pictures, and busts of the family were arranged on pedestals on the two sides of the room.
