Graves’s translation of The Twelve Caesars was a formative work in my teenage years and (along with Das Glasperlenspiel) defined my view of humanity for some considerable time and still rings true many decades hence.
His "Goodbye to All That" is a good memoir of the First World War. Though his Mythologies are the most readable or engaging one. I prefer Thomas Bullfinch for Mythology.
This is quite a cantankerous view of Graves.
"I, Claudius" was one of the most amusing and interesting books I've read.
