How can I use my Canon lenses on my Olympus camera?

I have a Canon Digital EOS Rebel XT and have purchased an Olympus Evolt E-300. Is there something I can use to be able to use my Canon lenses on the Olympus? I purchased the body only, so would rather use lenses I have than buy all new, obviously. Thanks!

I have been able to find an adapter that goes the other way -- in other words something that will let me use Olympus lenses on my Canon. Doesn't it follow that there should be one that goes the other way?

If you've found an adapter for Olympus lenses to Canon bodies, I would expect you CAN'T find an adapter to go the other way.
You can also fit Nikon lenses on a Canon, but not visa versa.
Apparently, Canon lenses sit closer to the sensor than with other brands. So when you want to use other brand lenses on a Canon, they should sit a bit away from the Canon lens mount - which is precisely what you need to squeeze in an adapter ring.

Sorry, no can do. The two are not compatible.

you will have to get an adapter. probably easiest to find online. but depends on which generation your lens and camera are.
