I guess this is the value of reading books on a whim, even if you don't end up finishing them.
What I noticed is that the characters are introduced in the reverse order to the title, which had always bugged me ever since I laid eyes on the film. Although the plotting shouldn't be laid out any other way - Clint Eastwood's introduction incorporates both Tuco and Angel Eyes in the same setting, after which we have been introduced to both of these characters - I always wondered why the title couldn't have been the more appropriate "The Ugly, The Bad and The Good", despite its lack of verbal elegance.
What I recently discovered is that this is a device called "hysteron-proteron", commonly employed by Homer in his epic The Odyssey, where this technique was brought to my attention. It is considered rhetorical, and therefore played for effect.
This, however, was unintentional, as the original Italian title is ordered "The Good, The Ugly and The Bad", however the rhetoric remains, and sets us up for a homeric grandiose epic all the same.
