Gully hole
Marble gully hole centrally decorated by a circle, bordered by a fillet, enclosing four elongated petals placed around a button carved in relief. The gully hole was probably part of a monumental fountain, placed on the pavement in connection to the drain of the terminal basin, a necessary device which let the water in excess flow down, as shown by some reconstructions in ancient Ostia.
It is difficult to set the object in a specific chronological frame, even though the use of marble for increasingly monumental architectonic decorative elements was given a strong impulse in Augustan age and its use continued in the following centuries.
