Part of the mosaic floor of a triclinium, or formal dining room, has been uncovered in the Roman city of Plotinopolis in northern Greece. Ichtyocentaurs, Nereids, and Plotini, the wife of the Roman emperor Traianus, are depicted in the images. “Both creatures are seated on a dolphin, and one of them is holding a scarf over the head like a ‘peplos. … A second panel is coming to light,” said archaeologist Matthaios Koutsoumanis.
