Historical definition

Chaomancy is the art of foretelling through the air.

Meaning

The definition identifies the medium of the practice. It does not specify one kind of cloud, colour, wind or vision, so those distinctions must come from the passage being read. The subject is foretelling by signs, rather than a general study of the air’s material properties.

Austromantia narrows attention to winds and adds a strongly critical judgement, while Hydromancy and Pyromancy name neighbouring practices through water and fire. The set is useful for navigating the dictionary’s divination terms without assuming that all use the same signs or receive exactly the same evaluation.
