um, yes they do....

rhyme isn't necessarily denote as "sound".....those are the scholory defintions of rhyme

end-rhyme (as well as eye-rhyme)
internal-rhyme
alliteration

only eye-rhyme isn't a rhyme based on sound....all others are.....alliteration is more like "begin-rhyme"....itz the sound at the beginning of each word.....

and yes, eye-rhyme was, and still somewhat is, a very popular form of rhyming....especially in rhyme-scheme.....the two essential rhyming styles of the past were "end-rhyme" and "eye-rhyme"........you saw a lot of eye-rhyme in epic poetry and sonnets and such....

as for Poe bein' a good poet.....boo!!!! i don't mind Poe, but he's not really renowned for his poems...except "The Raven".....but i never studied Poe

quite frankly, all throughout college, i never studied any of the so called big names in the olden days.....

we studied more of the modern big names....Ginsberg....Plath....AI....e.e. cummings....Ackerman....Rita Dove....etc, etc, etc....
