Wow, I really hate to be this pedantic, but it's semantic satiation. I only remember because I had a similar experience thinking it was "saturation" because it just makes more sense, but apparently we're wrong.

Wether or not Homer's writings are part of the Epic Cycle is very much a matter of... strong opinions of historians. There's good reasons to include them (They're about the same thing) and not to (Written later, and not lost, like all the other ones, so it makes the discussions annoying). We only know about most of the epic cycle because people wrote about the poems and made summaries and cliffnotes.
