 The caves were filled with dust.After removing the dust, Arnoul found bones; believing the bones to be those of the biblical Patriarchs, Arnoul washed them in wine and stacked them neatly.Arnoul carved inscriptions on the cave walls describing whose bones he believed them to be.This passage to the caves was sealed at some time after Saladin had recaptured the area, though the roof of the circular room was pierced, and a decorative grate was placed over it.
