Scuba diver exploring a Bichrome mosaic floor in the apodyterium of the Bath situated immediately to the north of the ?Villa con ingresso a protiro?, along the N-E shore of the Baianus lacus. The floor mosaic, in black and white tesserae, is framed by a monochrome triple band delimitating a central field with an agonistic subject, covering an area of approx. 12 square meters. In it four male figures are represented, made of black tesserae on a white background: two are athletes, testing themselves in wrestling, while the other two are badly preserved. As one of them holds a branch, he could probably be identified with the judge/trainer. Marine Protected Area of Baia, Naples, Italy, Tyrrhenian Sea
