In Homer's Odyssey, "When rosy fingered dawn appeared" is what type of figure of speech?

In general, the line "When rosy fingered dawn appeared..." is
first of all imagery. Imagery is an description that paints a mental image in the reader's
mind.

Specifically, this is also an example of a specific kind of
imagery known as personification. Personification is giving human characteristics to non-human
things. The dawn, actually, is not made of fingers: fingers belong to
people.

This could also be considered a metaphor. A metaphor is a
literary device. Defined, a metaphor is the comparison of two dissimilar things with similar
characteristics, as if they were the same.

In this example, the dawn
is being compared to fingers.

All of these literary elements named
above are known as figurative language. With figurative language, the reader does not take the
description literally, but figuratively.

So the statement is
considered figurative language. Imagery is an example of figurative language, and personification
and the metaphors are examples of imagery (which is a kind of figurative
language).
