This is an aryballos or 'oil flask', decorated in the Corinthian style using the black figure technique, with detail in added red.
The decoration is of a narrative scene. A man inscribed as AITHON plays a lyre and another one named ASTYKOTAS stands facing him. The name PHORBOS is over the bowl. On the other side one man on a horse with the name HIPPOMACHIDAS across the horse, to his back there is another man and the name KASTOR. The round base of the aryballos has a crescent rosette with eight petals, alternatively painted red and brown. A simplified maeander border is along edge of rim and the handle. On the top of the rim there is an eleven-petalled rosette. There is also a cross-hatching design at the top of handle and a triple guilloche on the back of handle, with incised central dots.
