 Two women, who appear to be modelled on the same person, sit on a carved Ancient Roman sarcophagus that has been converted to a water-trough, or a trough made to look like a Roman sarcophagus; the broad ledges here are not found in actual sarcophagi.How the water enters is unclear, but it leaves through a phallic-looking brass spout between the two women, next to an anachronistic coat of arms in the carving.This belongs to Niccolò Aurelio, whose presence in the picture is probably also represented by the spout.
