T. E. Lawrence’s Undergraduate Dissertation – Page 148

These few not very important castles have been dwelt on because they fill the gap between the square keeps and the fully-developed fortresses of the two great orders: and in filling it they show incidentally how entirely the East had lost touch with the West in military engineering. There is no castle in France with the least resemblance to any one of them, but there are numbers most clearly related all along the Byzantine frontiers. If these castles were the last pro-duced by the Latins, the classical view as to their entire absorption in Byzantine ideas would be more than justified: though it would be worth noting that the absorption took over half a century to bear fruit.
