One more round, waitress!
It’s a little tough to see in this photo, but this guy is getting up from a reclining position and has one finger in the air. He is laying on an empty wineskin. Get it? The Greeks and Romans were so cool they had a god of wine (Dionysus, aka Bacchus) and a goddess of beauty (Aphrodite, aka Venus). My kind of religion. Needless to say, those two got depicted in a lot of art.
The Getty had several conical wine goblets and cups on display. These would tip over on their sides when put down, spilling their wine, unless the holder drank it all before putting them down. Those Greeks and Romans knew how to have a good time, I guess….
