from the earth near Didymoteicho … Greek Reporter has the details:
A series of well-preserved archaeological finds have been discovered during this year’s excavations at what has been identified as the ancient Plotinopolis, situated in the outskirts of modern-day Didymoteicho, northeastern Greece. Plotinopolis was a Roman city founded by the Roman Emperor Traianus, who named it after his wife Plotini.
The hill of Aghia Petra, just outside Didymoteicho, has been the focus of archaeological interest since before World War II, while in 1965 a golden forged bust of Roman Emperor Septimius Severus was found there. From 1965 onward, the 19th Ephorate of Prehistoric and Classical Antiquities has been conducting systematic excavations in the area.
The mosaics unearthed, form part of the floor of a typical Roman triclinium, the formal dining room in Roman houses. Monstrous ichtyocentaurs and Nereids are depicted in the mosaic unearthed, along with portrayals of the God of Eurus River and Plotini.
The leader of the excavations, archaeologist Matthaios Koutsoumanis, describes the findings as: “both (creatures) are seated on a dolphin, and one of them is holding a scarf over the head like a ‘peplos’. It is certain by now that the scene with the Eurus River and Plotini is not the only one, as a second panel is coming to light. (…) Next year’s excavation has a lot of surprises in store for us.” That could make Plotinopolis one of the biggest excavations in the region of Thrace.

Back in 2005, there was a brief overviewish piece on the finds (up till then, of course) in Plotinopolis:
