The divination by salt.

Divination by interpreting salt. The origin of misfortune associated with spilled salt. Also known as Halomancy.

Alomancy (from Greek halo, 'salt', and manteia, divination), also called Adromancy, ydromancie, idromancie, and halomancy, is an ancient form of divination. Similar to many other forms of divination, the diviner casts salt crystals into the air and interprets the patterns as it falls to the ground or travels through the air. The diviner can also interpret patterns formed from the residue of a salt solution as it evaporates in the bowl.
