ART

UC Berkeley archeologists digging in southern Greece have unearthed a broken 2,500-year-old marble sculpture illustrating what experts call a crucial stage in the development of classical Greek art, the Associated Press reported Tuesday. The unusual 31-inch-by-18-inch bas-relief of a matronly woman with a bearded, bare-chested man standing beside her was found in November during excavations at Nemea of a sanctuary of Zeus, where athletic contests like the ancient Olympic Games were staged from the 6th to the 3rd centuries BC.
