The mosaic was fixed in a small niche in a wall of the buildings of the Imperial Villa on Posilipo, near Naples. One part of the site, now submerged beneath the sea in consequence of a post-Roman land movement, has already been described, but later surveys of the very extensive antiquities and ruins on the hill above still await publication. Among other discoveries, we have been able to find evidence that this fine property, stated to have been left by Vedius Pollio to Augustus, was still in the imperial possession as late as the reign of Hadrian, and that considerable alterations to the buildings were made at that period.
