The Mensa Ponderaria, or public weigh-house, was situated in the forum of the city of Tibur.
The building, which probably dates back to Augustan times, was discovered by chance in 1883. It represents one of those rare occasions in which the specific function of public weigh-house was identified thanks to the presence of two marble mensae, or tables, with concave cavities of different sizes where the official weights were housed. An adjacent structure, discovered in 1920, was probably dedicated to the imperial cult (Augusteum). An inscription provides information about the person who saw to the erection of the construction, the freedman Marcus Varenus Diphilus, magister Herculaneus, a rich and powerful college connected to the cult of Hercules.
