A review of Iphigenia and Other Daughters in the Columbia City Paper suggests, inter alia:
Classicists hate to admit it, but Homer and all who proceeded him in the tradition of ancient Greek theater (Euripides, Sophocles, Aeschylus, etc.) were of a mind to entertain just as much to educate and elucidate.
… er, no … it’s probably the other way around if anything. Actually, it doesn’t really reflect what Classicists think at all …

Also, I don’t think Homer was preceded by Greek tragedy…
It actually says proceeded … but that doesn’t quite make sense either.
