A number of ancient Roman statues might lie beneath the turquoise waters of the Blue Grotto on the island of Capri in southern Italy, according to an underwater survey of the sea cave.

Dating to the 1st century A.D., the cave was used as a swimming pool by the Emperor Tiberius (42 B.C. - 37 A.D.), and the statues are probably depictions of sea gods.

Carried out in collaboration with the archaeological superintendency of Pompeii, the Marevivo project aims at returning the Blue Grotto to its ancient glory by placing identical copies of Tiberius' statues where they originally stood.
