This doesn't answer your question, but day? If you are referring to line 6 of the Iliad (which I assume you are), shouldn't it be deh as in "red" or "Ed" - or so it says in almost every source I've seen (if you have other sources, I'd like to look at them).. "Day" is the ei dipthong, as in [face=spionic]aeide[/face].
Also, I am sure that "pop" is not omicron (unless you speak a different dialect of English, which is quite possible). I pronouce "pop" as something similar (but not quite like) "pahp". It's one of those weird English (or is it purely American?) vowels that most languages seem not to share.
