Anyone know The Odyssey in Greek?

I had a high school English teacher who knew (some of) Homer's Odyssey in the original Greek, and recited the line about Sisyphus pushing the stone up the hill only to have it roll back down eternally. In the Greek, he told us, the line was in dactylic meter and "simulated" the rolling, bouncing stone. Can anyone give me that line in English characters? As I recall, it ended something like "tempeta morphesus."
