Why Are Cows So Hungry?
The ancient Greeks had the same word: boulimia, again: "hunger of the cow". It's not a poetic metaphor, but e.g. sober Xenophon uses the term when his soldiers are too hungry to march on, Anabasis 5.4.7.
Strange that they both independendly picked the cow - and not the wolf or the locust or fire or whatever. Does anybody know why this is? And how do you say in your languages?
Maybe "cow" is just used to intensify the word that follows? Cf. German "Schweinegeld", "Schweinearbeit" etc. - literally "money of the pig", "work of the pig" - just means "a lot of money, work". Of course, this explanation doesn't satisfy my cow-hunger for stories.
