Ancient symbol for the axis or world mountain; a holy mountain or high place of God. To the ancient Egyptians it represented a stairway to heaven for the deceased, as well as the sun’s rays descending to earth. It was, thus, a threshold symbol.
More mundanely, as a pointed object, it is related to the phallus. The square base and four sides relate it to the square and the number four. The shapes of the sides also relate it to the triangle and the number three. It may represent a wider awareness, especially as related to spiritual issues; the mysterious unknown; spiritual initiation.
