This large floor mosaic was found while creating a car tunnel below the Termini railways station.
It belonged to a large hall only partially unearthed. According to professor Coarelli the room was part of a large imperial residence built for emperor Constantine after his roman conquer at the beginning of the IV century AD, and finished later on by emperor Costante.
The scene depicted is extremely interesting as it displays the capture of wild beast to be used in the anphitheatre during the morning hunting.
Same subject can be found in the famous villa Armellina in Sicily.
