In Othello, the villainous Iago plants seeds of doubt in Othello’s mind about the faithfulness of his wife, while advising him, “Oh, beware, my lord, of jealousy! It is the green-eyed monster that doth mock the meat it feeds on.” Othello, Act 3, Scene 3.
I found it interesting that Robin would constantly push Marian, whom he purportedly loved, to work her womanly wiles on Sir Guy, and then have frequent hissy fits when she did spend time in Guy’s presence.
Doesn’t love involve trust? And if you love someone, don’t you want to protect them from evil influences and keep them out of harm’s way? (Uhm, kind of like Guy did for Marian?) Robin considered Guy to be a monster, and yet he was always shoving Marian in the “monster’s” direction. Mixed signals there, I’d say.
And the whole “Peeping Blobbin” thing got really old. Every time you turned around, he was turning up like the proverbial bad penny. He started coming across as some sort of medieval pervert.
Of course, dearest Guy had his moments of jealousy, too. Particularly when a certain charming count showed up in Nottingham. In spite of all his protestations that he didn’t care about Marian anymore, we all knew he did.
It is thought that Shakespeare may have been evoking the image of cats here–often green-eyed and fond of toying with their prey before killing it, thus a cat will “mock the meat it doth feed on.”
