More fruits, but no vegetables

Here's Tantalus, tortured in Hell by fruit withheld: "Boughs, too, drooped low above him, big with fruit, pear trees, pomegranates, brilliant apples, luscious figs, and olives ripe and dark. . ." (Book XI line 704)

Ever hear of a luscious brussels sprout? a brilliant parsnip?

Is it possible the Greeks had no spinach? Is it possible Frank Zappa read the Odyssey and is compensating?

I know potatoes hadn't yet migrated from South America, but this is ridiculous.

I suppose Tantalus might not have been so miserable if it had been vegetables withheld: arugula, green beans, bok choy. Still it would depend on his diet, wouldn't it?
