Axinomancy

One of several obscure methods of divination using an ax, hatchet, or (rarely) a saw. Most of the methods involve throwing an ax into the ground, or swinging it into a tree, and interpreting the direction of the handle or the quivering of the blade.

Another interesting method is heating an ax-head in a fire until it glows, and then interpreting the colors and shapes. A variant, attributed to the ancient Greeks, is to balance a spherical piece of agate on the edge of the axe (held sharp edge up). The direction in which the agate rolls can be interpreted as needed.

Some sources claim that Psalm 74 refers to the use of axinomancy to predict the fall of Jerusalem, although in the text the reference to upright axes is not specifically for divination.
