One other observation on the bronze vase you posted. Compare-and-contrast the nicely chiseled abs on the Dearly Departed with his relatively-puny Wedding Tackle.
Now, speaking personally, were someone to immortalize me for all time on a bronze vase, I know what *I* would prefer them to exaggerate! And yet, on the Dearly Departed, they instead chose to make sure he had well-defined abs...
This thought tends to lend further credence to the notion that the rippling muscles on the Dearly Departed might not be too much of an exaggeration. Important enough for the artist to make sure we understood: this guy had six-pack abs. And the wedding tackle... not so much.
Yes, someone else above noted the small dinglebob, too. It’s rather an odd element, especially since his father was the notoriously randy Zeus!
Maybe the artist was working from a model with a small (ahem)? Or maybe it’s because the fellow is dead. Would that cause shrivellage? I’ve never seen a dead, naked man, and I’d prefer not to!
