What If Homer Made Helen Homely?

I am hoping today is the last time I review the Trojan War in English class--or with anyone, for that matter-- but to explain Act II, scene ii of Hamlet, it had to be done, and I did draw a lovely chart on the board, with all the main players: Achilles, Paris, Athena, Hera, Aphrodite, Hector, King Menelaus, King Priam, Queen Hecuba, Pyrrus, and of course, the "Face that Launched 1000 Ships" . . . Helen-- and I did learn something new today, as I wondered if the Greeks would have launched 1000 ships if Helen was NOT the most beautiful woman in the land, if she were homely-- but I did a bit of research and apparently, the Greeks STILL would have laid siege to Troy to bring her back, even if Helen were a horsefaced buck-toothed bride with a great sense of humor, because of The Oath of Tyndareus . . . this oath legally and socially bound kings Agamemnon, Odysseus, Ajax, etc. to mobilize their forces, regardless of what Helen looked like because Paris had violated and betrayed his host Menelaus and abducted his wife, but I'm sure the Greeks were more motivated because she was so attractive, because well . . . men.
