Intact bulbous-shaped unguentarium found in 1957 in the east Roman cistern on the south slope of the Acropolis. The foot is disk-shaped, the neck tall and cylindrical and the rim outturned. Horizontal grooves run around the body. Fire traces are retained on the body and the shoulder bears the inscription ΑΑ / ΕΙΝΟ.

Unguentaria were used for holding and transporting perfume oils as well as various other liquids and solids, such as honey, mastic and spices. Bulbous-shaped unguentaria were in use between the 1st cent. BC down to the 1st cent. AD. They were later replaced with glass unguentaria when the free-blown glassmaking technique enabled the mass production of this type of vessel.
