Abacomancy, alternatively amathomancy, is a rare form of divination based on the interpretation of the patterns in dust, dirt, silt, sand, or the ashes of the recently deceased. Reading the patterns is believed to give some insight into the future. Readers can either drop the dirt, sand, or ashes on a flat surface and start looking for a pattern that may represent symbols or pictures. Or they use the spell Iacio Pulvis to throw dust on light surfaces. They then interpret these symbols and pictures to what is going to happen in the future. Some look for certain symbols that are seen over and over.
The best prophecies can be divined from abacomancy when paired with other divinatory methods and techniques.
Abacomancy is a composed term that combines the Latin word ábaco (from abacus, from Ancient Greek ἄβαξ, ábax), "a calculation board covered with sand", and the Ancient Greek suffix mancy (from μαντεία, manteía), divination. Literally it means divination by a calculation board covered with sand.
