Archaeologists excavating the ancient Roman necropolis of Augustodunum, modern-day Autun in France, uncovered an extraordinary 4th-century AD cage cup, known as a diatretum.
The fragile vessel was carved from a single piece of glass and features an intricate openwork lattice surrounding the inner cup. An inscription reads “Vivas feliciter,” meaning “Live happily.”
Cage cups are among the most technically sophisticated and rare objects ever produced by Roman glassworkers. Because of their extreme fragility, only around ten complete examples are known to survive worldwide.
This discovery is especially important because it is the first complete cage cup of its kind ever discovered in Roman Gaul.
The diatretum was found among rich late Roman funerary remains containing hundreds of tombs and exceptional luxury artifacts. Archaeologists also uncovered delicate amber pins and intricate gold jewelry decorated with precious stones, revealing the wealth and craftsmanship associated with the people buried there.
For more than 1,700 years, the remarkable glass vessel survived underground.
Then archaeologists uncovered a masterpiece of Roman craftsmanship carrying a simple message from the ancient world:
Live happily.
