What about diseases?

Mesopotamians seem to have been of two (or three?) minds about the nature of diseases; the case of bennu [epilepsy] itself is illustrative of this, since in some cases it is referred to as a demon (itself a type of minor, perhaps supernatural, entity sometimes but not always labeled with a DINGIR determinative), sometimes it is marked as a DINGIR, and sometimes it is not marked or treated as a deity in any way, but discussed as what we might now call an inanimate phenomenon of nature. Although it seems not to have been always understood as a DINGIR, the evidence suggests that it was thought of as a DINGIR at least some of the time, or by some people.—Barbara N.
