Rhyme and pronounciation

"Tyger! Tyger! burning bright
In the forests of the night,
What immortal hand or eye
Could frame thy fearful symmetry?"

Did the words eye and symmetry rhyme when said aloud when Blake wrote these lines?
Also, I've seen poets rhyme "come" with "home" which clearly do not rhyme nowadays, is the lack of rhyme only due to the change of pronounciation over time?

Thanks
