A couple of days ago, as I was scrambling in the area of the caves north of Khirbet Qumran (immediately to the west of Kalia kibbutz), I discovered that some of them contained a number of strange symbols, small black circles, and graffiti supposed to be in paleo-Hebrew. All of them were kind of tidy, not something one would charactreize as regular vandlism. When I walked a couple of hundred meters to the north from the caves, in one of the side wadis I discovered this "masterpiece" (the photo is clickable):
I suspect this stuff was done by some weird sect or something of the kind. Does anybody have a clue who did it, and for what purpose?
