She might have been an angel arguing a point in the empyrean if she hadn't been, so completely, a woman.

In the poem -- one he had the good sense finally to abandon -- he pictured himself as a blind moth raised among butterflies, which for a brief moment had found itself rising upward into the empyrean to behold "Great horizons and systems and shores all along," only to find its wings crumpling and itself falling -- like Icarus -- back to earth.
-- Paul Mariani, The Broken Tower: A Life of Hart Crane

Empyrean comes from Medieval Latin empyreum, ultimately from Greek empurios, from en-, "in" + pyr, "fire."
