Yes that s probably the best way to view the development of that article However I can t go into that much detail myself because I certainly don t have the time to do that much research That quote from Iliad is rather odd Homer seems to be refering to Hesiod s earlier Theogony but the details are different The Perseus Digital Library whose pages take some time to load so for anybody reading this be patient translates Homer s quote just as you say line 14 onwards and has this to say for Theogony line 720 onwards I m no classicist but I d be weary of that bit of text it is certinly odd and probably should not be taken at face value so na vely As you say everywhere else as far as I know he refers to the underworld as the domain of hades As for Erebus the quotes from Iliad under the heading 3 from Homer Iliad at face value seem to indicate that it is a place But this is merely a misunderstanding of what Erebus is Erebus is the gloom the darkness of the underworld the place of dark mists as you put it Replace Erebus with darkness of the underworld or the like and the quotes make just as much sense as the assumption that Erebus is a physical location However I don t know of any source that explicitly states that it is a location in the underworld so again where does that quote come from
