The brightly-coloured geometric design, partly unearthed outside Negrar di Valpolicella near Verona, is thought to have been part of a villa archaeologists first started looking for in 1922.
“When I saw the mosaic it was very impressive because of the quality, the well-preserved colours, the preservation of the mosaic itself,” local mayor Roberto Grison told AFP.

Locals have known for years there were Roman artefacts in their part of the famous wine region.
A survey and some initial digging almost a century ago in 1922 hinted at what lay beneath – and the area of the discovery is called Villa, said Grison.
But until now, there hadn't been any big finds.
They added: “The superintendent will now liaise with the owners of the area and municipality to identify the most appropriate ways of making this archaeological treasure, which has always been hidden beneath our feet, available and accessible.”
