Was Jesus crucified on Skull Hill? or below skull hill?

There is nothing in the scriptures that tell us Jesus was crucified on top of Skull Hill or below it, in front of the escarpment.

However this ancient panting below dating back to the 1400's from the British museum reveals something interesting.

Notice behind Jesus is the escarpment.

Could this be evidence that Jesus was crucified below Skull Hill, in front of the escarpment?
