Which literary device does Sir Philip Sidney use in these lines from his sonnet sequence Astrophil and Stella?

When Nature made her chief work, Stella's eyes, In colour black why wrapp'd she beams so bright?

parallelism

simile

metaphor

hyperbole

That particular passage has numerous literary devices. Alliteration in the "Beams so Bright" and personification in "when Nature made Her ... ". The entire passage is a rhetorical question and it can be answered in he next passage with simile. Sydney answers the rhetorical question with a simile, saying her she is like a skillful painter and is like the sun. The fact that her black eyes shine bright is an oxymoron because black is dark and has no light with which to shine.
