The other day Laura Gibbs told me that Koine Greek and Attic Greek are the same language. The difference is about the same as that between modern English and Shakespearean English. I am now qondering what the relation is between Homeric and Attic. Is it the same degree of difference? More or less?
The Homeric dialect is an artificial creation. No one ever spoke Homeric Greek natively. In part, it's a mishmash of various Greek dialects that reflects the history of its oral composition. To fit the dactylic hexameter, an epic poet may use one form from Ionic and in the very next line, use a different form from Attica. There's also a lot of old history reflected in the Homeric dialect, some going right back to PIE times.
I personally think you might find it easier if you move from Attic -> Ionic -> Homeric. You'll recognise a lot of the forms that way.
