With his head tilted back, his mouth open as if singing, and his arms thrown out in a dramatic gesture, the man on this vase shows the effects of a long night of drinking. Luckily, a servant-boy is there, anticipating his master's needs. The boy stands patiently carrying his master's belongings--a walking stick and a basket covered with a cloth--and holds out a vessel for him to urinate into. The jug he offers is a chous, a special form of oinochoe (wine-pitcher), and it is the very same shape as the vase on which this scene is depicted. Reinforcing the connection, another chous stands at the far right of the scene, garlanded with ivy. Shape and decoration are, therefore, neatly tied on this vase.
The chous was used during the Anthesteria, a three-day religious festival in honor of Dionysos, the god of wine. A drinking contest was held on the second day of the festival, and these jugs were used to hold a standard amount of wine for the contest.
