From Connolly & Dodge, The Ancient City
Above we see four partygoers in various states of drunkeness (notice the fellow holding his head) being entertained by a naked woman (probably a hetaira), who is playing the double aulos and dancing at the same time. The objects (like the lyre) that appear to be suspended in space are supposed to be hanging from a wall. The man on the far right is playing a game of kottabos, which involved whirling your drinking cup on the index finger in such a way that the last few drops of wine might be hurled at some target.
