Gordon’s sketch of Jerusalem. Gordon visualized an imaginary skeleton superimposed on the city of Jerusalem: he fixed the skeleton’s pelvis at the Dome of the Rock, its legs on the City of David and its feet at the Siloam Pool. With this alignment, the hill containing the Garden Tomb had to be the skull. Gordon even saw a resemblance to a skull in the rocky hill with its dark cave “eyes.”
