A Companion to The Iliad

Excellent supplement to the Lattimore translation.
Gave just 4 stars just because of the nature of the book: it is basically a set of notes that could appear as endnotes or footnotes in the book, which makes reading a bit fiddly at best.
There was some higher-level summary notes for the beginning of each Book of The Iliad, which was helpful and more engaging. Would have enjoyed a bit more of these.
For me, it was easiest to use this book if I read all the notes for each Book or section of a Book before reading in The Iliad proper to minimize the juggling of two books. Of course, I went back and looked again if questions occured to me during my reading The Iliad, but generally I found that going back and forth on a line by line basis was not necessary or more helpful.
