The Odyssey (Homer, 8th century BC (7th century?)) (translated by Emily Wilson)

(525 pages)

I much enjoyed reading this then-new translation back in 2008; this 2018 translation was receiving rave reviews so I gave it a try. 

It's great - highly recommended.  Translator is remarkably skillful at using short words, active phrases.  In the introduction she explains that she decided to use iambic pentameter - different than the original Greek, but customary/suitable for English.  She also states that she decided to restrict herself to the exact number of lines used by Homer - a "difficult constraint" - she "wanted a narrative pace that could match its stride to Homer's nimble gallop".  (That phrase from the introduction gives a glimpse of what she did with the translation.)

Her introduction runs 80 pages and is uniformly helpful, interesting.

I'm not seeing a reason to recount the plot because it's so well known (and because I briefly did so in the above 2008 link anyway).  So many stories that are essentially immortal in their own right, let alone to consider that they are all collected in this single epic. 

Also needless to say - this has been read and enjoyed for centuries (millennia, actually) - that won't stop.
