Pristine 2nd-Century Roman 'Mosaic of the Argonauts' and Underfloor Heating System Uncovered in Rural Bulgaria

Archaeologists working in the Thracian Valley of southern Bulgaria have unearthed the remains of a luxurious Roman villa maritima featuring a stunningly preserved floor mosaic. The 150-square-foot artwork depicts scenes from the legendary voyage of Jason and the Argonauts, rendered in thousands of tiny, vibrant stone tesserae. The villa, dating back to the 2nd century CE, likely belonged to a high-ranking Roman official overseeing the regional grain trade.

Beneath the mosaic floors, the team discovered a fully intact hypocaust system—the Roman method of underfloor heating—complete with stone pillars and terracotta flues. The discovery of such an elaborate system and high-quality artistic expression in a rural outpost highlights the rapid Romanization of the Thracian provinces and the spread of Mediterranean luxury styles to the imperial frontiers. Future excavations will focus on the surrounding agricultural estate and slave quarters.
