Divination or fortune-telling by observing salt, its formation, or its behavior when scattered or dissolved.
From Greek 'halo-' (salt) plus '-mancy' (divination or prophecy, from 'manteia'). Like necromancy, geomancy, and cartomancy, this compound uses the Greek divination suffix combined with the substance being divined from.
Ancient people practiced divination with almost everything—salt, bones, birds, tea leaves, smoke—and halomancy reminds us that before science, people looked for patterns and meaning in nature's everyday phenomena, which is poetic even if not scientifically accurate.
