Question

What is the opposite of personification?

Answer 1

(Perhaps) `color(blue)("incarnation")` or `color(blue)("substantiation")`

Explanation:

I assume that you are looking for a term to express the concept of assigning a person to an inanimate form.

Example:

The Black Plague was the Genghis Khan of Western Europe, leaving only desolation in its path.
(Warning; this statement is probably not accurate; its only role is to demonstrate "incarnation").
