The classic text on Crusader castles and their relation to the military architecture of the West, written by T. E. Lawrence (of Arabia) while still an undergraduate at Oxford in 1910. His thesis was to guarantee him a first-class degree in Modern History. The original title was "The influence of the Crusades on European military architecture - to the end of the XIIth Century" by T.E. Lawrence, together with a volume of his letters regarding his visits to castles as a young man. This was published shortly, in fact a year plus one day, after Lawrence's death in 1935 by arrangement with his brother A.W. Lawrence. Lovely tight and clean copies. Bright gilt titles and bright leather. Boards relatively clean (they are often a little grubby). Very good plus, of this scarce and coveted and seminal Lawrence work. Direct orders welcome.
