"Greek archaeologists have discovered the image of a young, red-haired goddess being swept off to the underworld inside a 2,300-year-old tomb near the ancient site of Amphipolis in northern Greece. Identified as Persephone, daughter of Zeus, the goddess portrayed on a mosaic floor provides a key new clue to what in recent months has become a much publicized mystery: Who was laid to rest in the immense, marble-walled tomb 61 miles (99 kilometers) northeast of the Greek city of Thessaloniki?"

Note: Amphipolis was "originally the site of a Thracian town, Ennea Hodoi..," according to the Oxford Classical Dictionary, 3rd ed., revised. "After two unsuccessful attempts in 497 and 465 BC, it was colonized by the Athenians, with other Greeks ... in 437-436 BC. It owed its importance partly to its strategic position on the coastal route between northern Greece and the Hellespont, and partly to its commercial wealth as the terminal of trade down the Strymon valley, a depot for the minerals of Pangaeus and a centre for ship-timber."
