The cup is said to have been found in a Roman tomb at the ancient site of Caesaromagus in 1863, together with two glass jugs (81.10.168-169) and a coin of the Gallic emperor Postumus, which was minted between A.D. 260 and 268.

The two jugs and the cup are said to have been found in a Roman tomb at the ancient site of Caesaromagus in 1863, together with a coin of the Gallic emperor Postumus, which was minted between A.D. 260 and 268. The jugs’ attractive but rather impractical chain handles are distinctive of glassware made in the Rhineland.
