Golgotha means 'the place of a skull'.
A skull is a human head shorn of its dignity and beauty, with no light in its eye sockets, an empty vacuum in the brain space, and with none of that grace of hair which is the sign of man's strength and woman's glory. It is Mark's way of reminding us that when a man rejects Jesus Christ, all the lights of the world die down; there is nothing left but a grinning, bony death's head.—H. St. John
(Mark 15. 22)
