Nor do I forget the long centuries that have passed over the place since these medieval walls were built, any more than the far more interesting centuries that passed before they were built. But any one taking exception to the description on that ground may well realise, on consideration, that it is an exception that proves the rule. There is something very negative about Turkish rule; and the best and worst of it is in the word neglect. Everything that lived under the vague empire of Constantinople remained in a state of suspended animation like something frozen rather than decayed, like something sleeping rather than dead. It was a sort of Arabian spell, like that which turned princes and princesses into marble statues in the _Arabian Nights_. All that part of the history of the place is a kind of sleep; and that of a sleeper who hardly knows if he has slept an hour or a hundred years. When I first found myself in the Jaffa Gate of Jerusalem, my eye happened to fall on something that might be seen anywhere, but which seemed somehow to have a curious significance there. Most people are conscious of some common object which still strikes them as uncommon; as if it were the first fantastic sketch in the sketch-book of nature. I myself can never overcome the sense of something almost unearthly about grass growing upon human buildings. There is in it a wild and even horrible fancy, as if houses could grow hair. When I saw that green hair on the huge stone blocks of the citadel, though I had seen the same thing on any number of ruins, it came to me like an omen or a vision, a curious vision at once of chaos and of sleep. It is said that the grass will not grow where the Turk sets his foot; but it is the other side of the same truth to say that it would grow anywhere but where it ought to grow. And though in this case it was but an accident and a symbol, it was a very true symbol. We talk of the green banner of the Turk having been planted on this or that citadel; and certainly it was so planted with splendid valour and sensational victory. But this is the green banner that he plants on all his high cities in the end.
