I read “Seven Pillars” years ago. Pretty heavy, overboard on the adjectives ;-). My college library had a collection of architectural drawings of the Middle East that Lawrence produced, with descriptions; that was more interesting.
He was one of those strange guys the British Empire used to produce on a regular basis, i.e. Richard Burton (not the actor).
Lawrence also did a very good translation of Homer’s Odyssey under the name T.E. Shaw. It’s worth a read just for the violent scenes.
