The bottle dates from approximately 325 A.D. This bottle was one of several found in the sarcophagus, but is the only one with the contents still preserved.
The greenish-yellow glass amphora has handles formed in the shape of dolphins. The ancient liquid has much silty sediment. About two-thirds of the contents are a thick, hazy mixture. This is most probably olive oil, which Romans commonly used as a preservative for wine. The oil was layered atop the wine to preserve it from oxidation. Cork closures, although used at the time, were uncommon.
The bottle is on permanent display at the Historisches Museum der Pfalz near the town of Speyer, Germany.
