About the Word:
An ancient means of determining guilt, axinomancy involved balancing an ax on a post, and reading a list of names aloud. If the ax moved at a particular name, that person was deemed guilty.
In another (equally strange) version, a marble was placed on a redhot ax; the motion of the marble signaled guilt.
