I find that Fagles is very majestic -wonderful, really- but he's also very liberal (poetically) and definitely did not limit himself to the same number of lines as Homer as this project did.
FWIW I gave GPT-5.5 two lines of William Cowper's translation (long out of copyright to avoid any filters) without web search and not only was it able to identify it, it was able to continue it verbatim for roughly 30 lines at which point it went off course, but only by skipping like two books ahead. If I had supplied the original text as an anchor it presumably could have kept going.
I didn't try it with Fable because I'm lazy, but all these translations (presumably the ones within copyright too, given the lawsuits) are definitely well known by these models.
Ok, but this clearly combines a few translations line by line if you work through it.
…and all of its training data.
