Personification is giving human qualities to animals or objects.
Example:
a smiling moon, a jovial sun
In "Mirror" by Sylvia Plath, for example, the mirror--the "I" in the first line--is given the ability to speak, see and swallow, as well as human attributes such as truthfulness.

I am silver and exact. I have no preconceptions. Whatever I see I swallow immediately Just as it is, unmisted by love or dislike. I am not cruel, only truthful--

In John Keats' "To Autumn," the fall season is personified as "sitting careless on a granary floor" (line 14) and "drowsed with the fume of poppies" (line 17.)
